In the next sections, I’ll cover the Ida Wave’s clit vibration power and rumbliness.

Here’s the main conclusion:

The Ida Wave has one of the best clit motors of any dual-stim wearable. It’s got the most rumbly clit motor of the dual-stim wearables I’ve tested, and has great power. It’s strong enough for me to orgasm hands-free, and while some others have even more strength, the broad external arm helps the vibrations reach my clit more effectively than many stronger toys.

In the next sections, I’ll cover the Romp Party’s clit-motor power and rumbliness in-depth.

Here’s the main conclusion:

The Romp Party falls in the middle of the panty-vibe pack on clit stimulation. Its motor is technically strong, but the straight design doesn’t transfer enough of that strength to my clit, and the vibrations are buzzy on the settings I actually use. In this price range, for a more stimulating panty vibe, go with the VeDO Niki if you want a physical remote, or the NS Novelties Techno Lucy if you want an app.

Power vs Frequency Graph
How Strong Is Each Power? 

The Ida Wave has strong clit vibrations – strong enough for me to orgasm hands-free. Its ten power levels span from a very gentle 1.0 up to 8.5 out of 10, with gradual steps for a comfortable, slow build.

The vibrations transfer really well to my clit too. With hands-free vibrators, the toy’s shape and fit have to naturally carry the motor’s strength to your body. The Ida Wave’s design does this very well: the tight angle of the internal arm pushes the clit arm firmly against my body, and the broad shape distributes this pressure evenly and consistently (and very comfortably).

Ida Wave Internal and External Arm
The tight angle between the internal arm (left) and external arm (right) presses the external arm’s motor tightly, but comfortably against the clit.

Of the dual-stim wearables I’ve tested, the Lovense Dolce and Lovense Flexer reach higher raw top powers, but neither delivers their power to the clit as effectively as the Ida Wave.

The Romp Party has one of the strongest top settings of any panty vibrator I’ve tested, though its design doesn’t transfer all of that power to your clit. The motor reaches a 9 out of 10 in vibration strength at its highest setting. Of my panty vibrators, only the Lovense Ferri reaches a higher top power. The Romp Party is just behind it. Spread across 7 distinct power levels from a gentle 1 out of 10 warmup up to that 9 at the top, it has one of the widest power ranges of any panty vibrator in this price range.

But with a wearable, you can’t press harder for more intensity the way you can with a handheld – the toy’s shape and fit has to naturally deliver the motor’s strength to your body. This is where the Romp Party’s design works against it. Its strongest vibrations are at the middle of the toy rather than at the clit where most panty vibrators concentrate them, so I had to situate it up higher in my underwear to feel more of the vibrations. This felt a bit unnatural, and my underwear kept trying to push it out of that placement.

Romp Party Center Vibrations
The Party’s vibrations are strongest right here at the middle of the toy, which does not naturally sit at the clit when worn.

The Romp Party is also straight rather than contoured, so it doesn’t sit snugly against my clit the way better-fitting panty vibes with a curve do, like the Lovense Ferri and VeDO Niki. When I get the placement right, it’s reasonably stimulating, but getting it right takes more effort than I want from a hands-free toy and requires frequent readjustments.

Romp Party Straight Design vs Lovense Ferri Curved Design
The Romp Party (left) is straight, and gets easily tilted out of place. While the Lovense Ferri (right) is curved, and stays close against the body.

So the Party feels less stimulating than the raw 9 out of 10 strength suggests. If you want a panty vibe in this price range that delivers more of its motor’s strength to your clit, the VeDO Niki is a better option – its top setting is a notch lower at 8 out of 10, but its body-contoured shape gets more of that power where you actually feel it, so I can orgasm with it hands-free. For the strongest motor and best vibration transfer of any panty vibrator I’ve tested, try the Ferri for about $40 more.

We rate wearables with rumbly vibrations higher than buzzy ones because rumbly is what most people prefer. But it’s definitely a personal preference, so consider what you like.

The Ida Wave’s clit motor is one of the most rumbly of my dual-stimulation wearables. Its lowest power setting is extremely rumbly at 46 Hz, the middle of its range is moderately rumbly at 68 Hz, and its top setting reaches neutral at 84 Hz – it never crosses into buzzy territory. My other dual-stim wearables are buzzier: the Lovense Dolce starts rumbly on low (49 Hz) but climbs into extremely buzzy at its top, and the Lovense Flexer is extremely buzzy at every power level.

The Ida Wave has a more rumbly clit motor than the Dolce (click on the Dolce’s G-spot motor under the graph to remove it from the graph and show only the clit motors).

Rumbly vibrations travel deeper into your body and tend to feel less ticklish than buzzy ones, which is part of why many people prefer them. While I can orgasm just as well from buzzy wearables as rumbly ones, the Ida Wave will be best for those who prioritize rumbliness.

We rate panty vibrators with rumbly vibrations higher than buzzy ones because most people prefer them, but it’s genuinely a personal preference.

The Romp Party is not very rumbly.

Its lowest power level is technically extremely rumbly at 59 Hz, but that’s the warmup setting – too gentle for the rumbliness to feel very stimulating. From there, frequency climbs as power does: the toy is moderately buzzy by its mid-range at around 100 Hz (about average for a panty vibe), and extremely buzzy at 127 Hz at the top. Since the vibrations don’t transfer well, I need to crank the power to feel anything, so most of my use with this toy is in the buzzy range.

If you care about rumbly vibrations, the VeDO Niki is one of the only truly rumbly panty vibrators and it’s an excellent choice in the same price range.


G-spot Stimulation: Main Takeaways


G-spot Stimulation 7.5 N/A
Stimulation from Motion 7.5 N/A

Like all panty vibrators, the Romp Party only stimulates your clit – not your G-spot. Since most women need clit stimulation to orgasm, a panty vibrator is often the right type of wearable. But if you’re interested in G-spot stimulation instead, see all our recommendations for the best egg vibrators here.

I really enjoy the Ida Wave’s G-spot motion and it hits my G-spot well, but it’s somewhat subtle – like gentle fingering. It adds depth to my orgasms driven by the clit motor, but isn’t the main event on its own.

This rotational motion is one of my favorites, because this angle can direct pressure against the front wall where my G-spot is. Of the motion-based wearables I’ve tested, the Ida Wave hits the G-spot best: the “fingering” motion of the Lovense Flexer actually creates more clit movement than internal movement. And in-and-out thrusting toys like the Lovense Vulse feel good but don’t press on my G-spot specifically. The Ida Wave’s motion is also more stimulating than the Lelo Hula Beads which have too little range of motion to reach my G-spot reliably.

The different motion types of the Lelo Ida Wave, Lovense Flexer, Lovense Vulse and Lelo Hula Beads.

The stimulation is on the gentle side because the internal arm is flexible, so the pressure is light. If you like substantial force on your G-spot, handheld G-spot toys like the We-Vibe Nova 2 or Lovense Nora allow for much more leveraging pressure. But what I enjoy about the Ida Wave is that it’s effortless.

I can let the clit vibrations bring me to orgasm hands-free while the G-spot motion makes the orgasm stronger and more full.


App Control: Main Takeaways

Close-Range Features Rating 6.2 N/A
Long-Distance Features Rating 2.6 N/A
Close-Range Connectivity Rating 7.8 N/A
Long-Distance Connectivity Rating 7.4 N/A

In the next sections, I’ll cover the Lelo app’s close-range features, long-distance features, and connectivity in detail.

Here’s the main conclusion: Lelo’s app is clean, easy to use, and reliable, but it’s basic compared with the best vibrator apps.

Lelo Ida Wave Close Range Play Options in App
The control options available in the Lelo app during Close Range play.

Close-range and long-distance controls works well for adjusting intensity, choosing preset patterns, or controlling power through your phone’s movement. But there’s no custom pattern creation, sound sync, multi-toy control, or independent control over each motor. Long-distance connections are reliable, but the experience is bare-bones with no video calling or photo sharing. Bluetooth connectivity is solid during normal use, though heavy body interference can cause dropouts.

If basic, reliable control is enough and you primarily want the Ida Wave for its comfortable motion and rumbly clit vibrations, the app works well. If a feature-rich app and engaging long-distance experience are priorities, go with a Lovense dual-stimulation wearable like the Lovense Dolce or the Lovense Flexer if you still want motion.

The Romp Party isn’t controlled through an app. App control lets you create custom patterns, control multiple motors or toys, play long-distance, and lets a controlling partner see exactly what your toy is doing. If that matters to you, see our app-controlled recommendations in these guides:

The Lelo app’s close-range features are clean, easy to use, and work well – but they’re very basic. It’s essentially a glorified remote control which can be good if you like simplicity.

You can adjust intensity, choose preset patterns, and use Lelo’s unique motion-control feature like their physical remotes provide. But it lacks the advanced features better apps offer, like custom pattern creation, music/sound sync, separate control over each motor, and the ability to control multiple toys at once.

Lelo Ida Wave Manual Mode in App
Manual Mode in the Lelo app.

Manual mode is just a picture of Lelo’s remote and + / − buttons to raise or lower intensity. It works well, but with 10 power levels, it takes lots of repeated taps to reach high power. Better apps like Lovense’s feel smoother because you can tap or drag directly to the intensity you want instead of clicking a button several times.

Lelo Ida Wave Screwing Mode in App
Screwing mode adjusts intensity based on how far you twist/tilt your phone.

For faster intensity changes, use the Screwing mode. This adjusts the toy’s power based on your phone’s tilt – level for gentle vibrations, closer to 90 degrees for stronger. This is also a great way to control your toy without staring at a screen.

Lelo Ida Wave Shaking Mode in App
Shaking mode adjusts intensity based on how fast you shake your phone.

Shaking changes intensity based on how hard you shake the phone, but I think it takes too much energy, so it’s not very useful.

Lelo Two Motor Patterns in App
Patterns available in the Lelo app.

On all 3 screens, you can select a pattern and control its intensity. The pattern names are vague like “Delighted” or “Overjoyed” instead of descriptive like “Waves” or “Pulses”. And the app shows small waveform icons for each motor, but you don’t see them until you’ve selected the pattern. So you have to select and try each pattern to know what it feels like.

It’s missing more advanced functionality other apps provide. There’s no custom pattern creation, no music or sound-reactive control, no multi-toy control, and no individual control over each motor. Each pattern in the Ida Wave’s app assigns a preset waveform to both motors, and some Modes give the clit and G-spot motors different patterns. But any intensity adjustment applies to both motors together, so you can’t turn up the clit vibrations while keeping the G-spot motion slow for example. Better apps like Lovense allow individual control of each motor.

One small annoyance: the app requires an account even for close-range solo use. It usually stays logged in, but it sometimes signs me out, which is frustrating when I’m ready to use the toy.

For simple, reliable close-range control, the Ida Wave’s app is good. But if you want more advanced app features, the Lovense Dolce is a good dual-stimulation wearable with a better app.

Lelo’s long-distance experience is very basic.

It works for offering a partner simple, reliable control of your toy from anywhere in the world, but it doesn’t have the communication features that make long-distance feel more like sharing an experience together: no video or voice calls, no saved partners, no photo or voice messaging, no custom pattern creation, and you can only send text messages when you’re both in an active session.

Lelo App Create or Join a Room
You have to create a new room each time you want to share control.

To start, you create a new Room and send your partner the code outside the app. That’s fine for one-off sessions, but you have to create a new room every time. There are no saved partner profiles, online status, auto-accept settings, or permissions. So with a regular partner, you have to start from scratch each time.

Lelo Ida Wave App Long Distance Call Controls
Your partner’s control options and view during a “call” – there is no video call option.

Once connected, the controlling partner gets a version of the same Play screen used for close-range control: they will use the Manual mode, and the Screwing/Shaking motion modes to contol your toy. Lelo does add two useful long-distance controls: a drag-to-position dot for setting intensity quickly, and a voice-control mode that changes power based on sound picked up by the phone’s mic. Both make it quicker to set a specific intensity than tapping + / − repeatedly.

Lelo App Text Messaging During Long Distance Call
You can send text messages back and forth during a call, but the message history is not saved, so you can’t see it anymore after the call is over.

But it lacks lots of communication features that make most long-distance toys feel fun and connecting. There’s only text messaging, with no message history once the room ends, so you can’t go back and reread fun messages. Video or voice calls have to happen in another app, like FaceTime or Zoom. But if you each have a Lelo toy, you can each control the other’s toy.

If long-distance play is a priority, the Lovense Dolce or Lovense Flexer is the better dual-stim wearable. Lovense has in-app video, messaging, saved partners, permission settings, and detailed controls so your partner can make custom patterns. Lelo is fine for basic control-sharing, but Lovense is much stronger for ongoing partner play.

The Ida Wave’s close-range Bluetooth is good for solo use: pairing is reliable, commands consistently go through, and the range is strong – 215 feet in our test without any blockage. It can be sensitive to too much body tissue coming between the phone and toy, but this doesn’t happen much in normal use.

The first time you connect, you’ll add the toy to your list which takes a few clicks. After that first one-time pairing, I just tap the toy from the My Toy list, tap Play, and it connects within a few seconds.

The Ida Wave stays connected well when the phone and toy have a clear path, but Bluetooth struggles when a lot of body tissue sits between them. In our body-interference test, it handled light body interference but dropped at the two harder angles with more material blocking the signal.

For most people this won’t really be an issue with the Ida Wave. Our test runs harsher than real wear. The Ida Wave’s receiver is in the external arm and often will have a relatively clear shot – especially since this toy is best in bed rather than wearing around where your partner might be at an odd angle like controlling your toy from behind you.

Lelo Ida Wave On-Toy Controls Photo
To re-pair, you often have to press the on-toy button.

If the connection drops between your phone and the toy, the app won’t automatically reconnect when the signal returns. You have to go back to the toy’s connection page, and press the physical button on the Ida Wave itself to re-pair. Since the button’s on the external arm, it’s not much trouble, but still takes effort.

Connecting in long-distance mode through a “room” is reliable because your partner’s phone isn’t talking directly to the toy. Your phone controls the Ida Wave over Bluetooth, and your partner’s phone connects to yours over Wi-Fi or cell data. As long as your phone stays near the toy and both internet connections are decent, the long-distance connection works well.

One small long-distance quirk: if the controlling partner locks their phone or leaves the app for more than about 30 seconds, they drop out of the Room and have to re-enter the code. The wearer’s connection doesn’t drop – control just pauses until they rejoin.

For most typical uses, the Ida Wave’s connection is solid. But if the best connectivity is important to you, the Lovense Dolce or Flexer is a better pick. They handle tougher body-blocking angles better, and are stronger overall for app-controlled play.


Remote Control: Main Takeaways


Remote Control N/A 9.3
Features Rating N/A 9.0
Connectivity Rating N/A 9.5

The Lelo Ida Wave doesn’t include a physical remote control. A remote lets you adjust the toy by feel – without pulling out your phone. Though there’s other downsides like less depth and no visual feedback to help your partner know what your toy’s doing. If you want to consider options with physical remotes, see our recommendations in these guides:

In the next sections, I’ll cover the Romp Party’s remote features and connectivity.

Here’s the main conclusion:

The Romp Party has a basic, reliable remote – stable connection, instant response, and separate + and – buttons to adjust the power. Remotes can be useful if you don’t want to use a phone to control your toy.

Its main limitations are typical of remotes versus apps: less partner feedback and shorter range. If you want this more-detailed control, go with the Lovense Ferri for the best app control, or the NS Novelties Techno Lucy for a budget-friendly app experience.

The Romp Party’s remote is simple, but works well – the two-button design gives all the control you’d need for power adjustment. Its few minor downsides are typical of remotes in general compared to apps.

Power control is fast and direct – the dedicated + and − buttons let you move forward and backward through seven power levels, and there are no vibration patterns to cycle through at all, which keeps the remote uncluttered. And you won’t accidentally switch from a constant setting to a pulse or wave.

Wearables Remotes Size Comparison
The Romp Party’s remote (farthest left) compared in size to other wearables’ remotes.

The remote is comfortable to hold – a good size, fits easily in my hand, and the buttons are easy to tell apart by feel so I don’t have to look at the remote. This is a big upside compared to an app-controlled toy if you don’t want you or a partner to have to be tied to a phone. With the Party, you can make adjustments from your pocket without looking.

Like most panty-vibe remotes, the Romp Party’s partner feedback is just a faint blink when you press a button – there’s no way to tell what setting the toy is on. That’s fine if you’re using the toy yourself, and many partners won’t mind. But others find it less engaging when they can’t tell what the toy is doing or what you’re feeling.

An app-controlled panty vibe gives your partner real-time visuals of the toy’s vibrations, which can make controlling it feel more engaging. If that’s a priority for you, the Lovense Ferri is the best app-controlled panty vibe.

Max Remote Range N/A 55 ft

The Romp Party’s remote connectivity is excellent, though its maximum range lands in the middle of the pack.

The remote maintains a reliable connection through typical interference. Body tissue between a remote and toy is the main thing that typically breaks a remote’s signal during partnered control. Remote’s signals are weakened by water-rich materials like your body sitting between the remote and your toy.

Our body-interference test simulates this scenario at three progressively challenging angles, and the Romp Party holds a stable connection through all of them. Our test also runs harsher than typical real-world conditions, so partner-controlled play should stay reliable in practice.

Button presses register instantly – the toy reacts before my finger even lifts off the button. And the remote is always connected, so there’s no reconnection routine when starting to play.

One quirk: occasionally a click sounds as if it went through but the click was too light or off-center to make it actually take affect. You do have to give a deliberate, full press of the button.

Romp Party with Remote and Lovense Ferri with App
App controlled vibrators like the Ferri (right) typically stay connected over a greater distance.

The remote reaches about 55 feet in our open-air range test – measured with clear line-of-sight and no body interference. This is middle-of-the-road for the wearable vibrators’ remotes we tested, and real-world range will likely be shorter once objects and body interference come in. But the Romp Party has comfortable headroom for most activities, and especially any same-room use. If you need an especially long range, many app-controlled toys stay connected much farther – for instance, the Lovense Ferri stayed connected until 190 feet in our same test.

On-Toy Control Comfort 10.0 7.5

Like most wearables, the Ida Wave’s on-toy controls are limited by design – you’ll mostly control it through the app. The button is a single-button cycle for 7 vibration patterns, with only one vibration power level accessible on-toy. The rotating internal arm spins at one fixed speed regardless of which setting you select.

For the full 10 power settings and control over the arm’s speed, you have to use the app.

If you do have to use the on-toy button, the button placement is good. On most wearables, pressing the button often means pushing the toy uncomfortably against you or removing it completely first. But the Ida Wave’s button is on the side of the external arm.

Lovense Dolce On-Toy Controls Photo
Most toys’ buttons are on the top of the external arm, as shown here with the Lovense Dolce. Pressing the button(s) pushes the toy against your body, which can be annoying. I prefer the Ida Wave’s side-button placement.

It’s comfortable and easy to press, and doesn’t push the toy uncomfortably against your body, making it decent as a backup if you don’t feel like using the app.

Like most panty vibrators, the Romp Party’s on-toy controls are limited by design – the toy is inside your underwear during use, so you’ll typically rely on the remote.

There’s a single button on the toy that cycles forward through the seven power levels, with no patterns mixed into the loop. Unlike the remote, there’s no minus button – dropping back to a gentler setting means clicking forward until you start over in the cycle. Since there’s not many settings it doesn’t take too long to cycle, so the controls work fine if you also want to occasionally use it like a handheld vibe.

The button is well-placed: easy to feel and press without looking, and centered in the middle of the toy rather than tucked at the top the way most panty-vibe buttons sit. Pressing it does push the toy against you, which some people may find slightly uncomfortable, but the mid-toy placement distributes the pressure more evenly across your body than a button near your clit would.

The on-toy button works fine as a backup, but the remote is the main way you’ll use the Romp Party.

Shape Degrees of Freedom 0 0

The Ida Wave is the least secure-fitting dual-stim wearable I’ve tested. I still really enjoy this toy, but you can’t wear it around. And even in bed, I have to make occasional adjustments.

The rotating internal arm is small and flexible while the external arm is broad and heavy, so the toy’s own weight slowly works the internal arm out. It’s flexible, but not adjustable, so there are no hinges to actually re-shape the toy to make it more secure.

In bed, the Ida Wave stays workable but never feels fully reliably anchored. I can roll, shift positions, even kneel, but I find myself adjusting it or pushing the internal arm back in a few times per session. The clit vibrations are stimulating, but for the best experience, plan to use your hand every so often to re-position it. If you’ll find that annoying, dual-stimulation toys without motion like the Lovense Dolce are much more secure.

Lelo Ida Wave and Lovense Dolce Internal Arm Comparison
The Ida Wave’s (left) slim internal arm and heavy external arm makes it easy for the toy to slip out. Thicker internal arms, like the Dolce’s (right) take more effort to get in, but also take a firm tug to pull back out.

The Ida Wave is not designed to be worn around. When I walked around with it in, I had to keep pushing it back into position; only my underwear stopped it from falling all the way out. It also bumps against the inside of my legs, making walking awkward. With any sort of heavier activity like running or jumping the Ida Wave pulls most of the way out.

Lelo Ida Wave with Lovense Ferri and Lovense Lush 4
Panty vibrators and egg vibrators like the Lovense Ferri (left) and Lovense Lush 4 (right) are better designed to wear while walking around.

If walking around or moving with the toy in is part of what you want from a wearable, the Ida Wave isn’t built for it – and really none of my strong dual-stimulation wearables are easy to wear around. A panty vibrator like the Lovense Ferri or egg vibrator like the Lovense Lush 4 are much more secure. You can even wear both of these at the same time and control them through the Lovense app.

The Romp Party’s secure fit is great in bed but gets worse with activity. It’s much more secure than panty vibrators without a magnet that just sit loosely in your underwear. But its long, straight body doesn’t curve along your vulva, so it shifts off my clit more easily during walking and moves around during heavier activity than curved toys – even though the magnet keeps the toy itself anchored to my underwear.

Straight toys only maintain a small contact area, and the protruding ends of the toy can easily tilt pressure away from the clit. While curved toys stay snug against the body to maintain consistent contact.

In bed, the magnet locks the toy to my underwear and doesn’t slip from where I position it. The toy moves a bit with my body when I shift around, but it stays anchored and keeps a good position for stimulation fairly easily – you’re generally not moving around a ton here so the toy doesn’t shift off your clit that much. Form-fitting underwear helps; loose underwear lets the toy bounce against me more.

Walking is where the design starts working against the toy. The toy stays anchored to the underwear, but it doesn’t press as firmly against my body as panty vibes that curve with your vulva and it wiggles around more easily – so contact between the toy and my clit goes from solid in bed to only decent during light activity like walking around. When wearing a thong, the toy is long enough that the back end can poke out of the underwear as the toy starts to shift; full-backed underwear keeps that from happening.

Heavier activity is the hardest test. Running and jumping jacks bounce the toy around enough that stimulation drops off even more. It doesn’t fall out, but it’s not a good experience.

Magnet Size Comparison of Romp Party vs NS Novelties Techno Lucy
The smaller magnet size on the Party (left) is not as secure as larger magnets like the NS Novelties Techno Lucy (right).

The magnet design is part of why this toy shifts more. It’s a small disc with decent strength, but it’s not big enough to anchor the long body of the toy completely and prevent the end from swinging around as I move. Still, the magnet is a clear improvement over panty vibes that just tuck into your underwear.

If you want a panty vibe that stays put while you move, the VeDO Niki is a better option in this price range – its body curves, so it stays firmly against your clit during walking instead of shifting off the way the Romp Party does.


Comfort


Comfort Rating 6.0 7.5
In Bed 7.4 8.0
Light Activity 4.5 7.0

The Ida Wave is much more comfortable in bed than it is for walking around. Lying down, the slim internal arm is pretty comfortable, and the broad external arm distributes pressure evenly. But once I’m standing or walking, the toy starts to pull out, which can make it pinch uncomfortably.

Lelo Ida Wave showing how broad the clit arm is

In bed, the internal arm is slim enough that it doesn’t limit my movement as much as more bulbous internal arms. The external arm is broad enough that I can’t fully close my legs around it, but my legs help to keep it in place. And this breadth helps spread the pressure out instead of pinching, like the narrower Lovense Flexer can.

The Ida Wave’s broad external arm anchors the toy against the internal arm’s rotation motion. This gentle rocking and broad pressure is very comfortable.
The Flexer’s slimmer external arm moves much more, which can be distracting or overstimulating to some.

Walking around is the weak point. As the internal arm slowly works its way out, it can press uncomfortably against my pubic bone. So if mobile comfort is your priority, try a panty vibrator like the Lovense Ferri or egg vibrator like the Lovense Lush Mini instead. Or try wearing them both at the same time for dual-stimulation that’s more comfy to wear around.

The Ida Wave is best treated as an in-bed wearable.

The Romp Party is comfortable in bed if you like focused, slim contact against your clit, but it shifts around enough when walking to cause some slight discomfort.

Romp Party Precise Contact Area vs NS Novelties Techno Lucy Broad Surface
The Romp Party (left) is much slimmer for more precise contact compared to the broader Techno Lucy (right).

In bed, I’m not moving a ton, so the toy sits consistently against my body. The silicone is soft and smooth with no poke-y spots. While the contact is more focused than what I get from broader, contoured panty vibes, the pressure stays light enough to feel comfortable.

When walking, the slim, straight shape moves around more than a broader or contoured toy would. The materials are still smooth and there’s no pinching, but the toy taps against my clit a little more than I’d like. If wearing it with a thong, the back end sometimes sticks out of your underwear which is a distracting feeling.

Romp Party with VeDO Niki and NS Novelties Techno Lucy
I find the VeDO Niki (middle) and Techno Lucy (right) more comfortable because of their curved design.

For comfort, both the VeDO Niki and the NS Novelties Techno Lucy are better picks in this price range – each is more form-fitting to keep the toy from shifting uncomfortably.

The Lelo Ida Wave is very discreet – especially surprising since toys with motion are typically loud.

When held in the open air, the decibel readings are somewhat loud on paper – about 45 dBA on low and 56 dBA on high. But once you’re actually wearing the toy, the body dampens both the vibration and the motion noise substantially.

Motion-based wearables are typically louder – the Lovense Flexer here is a prime example.

The Ida Wave was fully masked at every power level in our Background Noise Masking subtest. In this part of the test, I wear the toy while my partner listens from three feet away and we play pink noise through a speaker at quiet, moderate, and loud volumes (56, 62, and 68 dBA). He couldn’t hear the Ida Wave at any strength under any of our three tested background volumes – and even when he stepped right next to me to check the sound, he could only pick up the vibrations, not the rotating motion at all.

Behind a closed bedroom door, the Ida Wave was also inaudible. For this part of the test, my partner listens directly outside our bedroom door while I use the toy in bed. I use it like a handheld toy since wearing dampens sound, and some people want the flexibility to safely re-position wearables or use some of them handheld. Holding the toy instead of wearing it gives us the most conservative results. He couldn’t hear the Ida Wave at any setting from behind the door.

The Ida Wave is the quietest of my strong dual-stimulation wearables.

The Romp Party is in the most discreet group of wearable vibrators I’ve tested. However, more stimulating panty vibrators like the VeDO Niki and NS Novelties Techno Lucy are similarly quiet, so they’re better options for most people.

The Romp Party’s decibel readings on low and high power were extremely quiet, too quiet for our Sound Level Meter to pick up on. The ambient room noise was 35 dBA, and the Romp Party never measured higher than this.

For our Background Noise Masking subtest, I wear the toy while my partner listens from three feet away and we play pink noise through a speaker at quiet, moderate, and loud volumes (56, 62, and 68 dBA). He couldn’t hear the Romp Party at any vibration strength under any of the three tested volumes of background noise. It’s audible in our room without any pink noise playing – but every wearable I’ve tested is, no matter how gentle and quiet its vibrations are.

For the closed-door part of the test, my partner listens directly outside our bedroom door while I use the toy in bed. I use it like a handheld toy here, since wearing dampens sound and some people want the flexibility to safely re-position the toy or move it around. Holding the toy instead of wearing it gives us the most conservative results. He couldn’t hear the Romp Party from behind the door on any setting.


Battery Life

Battery Life on High Power 135 minutes 115 minutes

The Lelo Ida Wave lasted 135 minutes at top power in our testing – the longest battery life of any dual-stimulation wearable I’ve tested. And since you’ll spend plenty of time on lower and middle settings too, real-world runtime is typically longer. That’s plenty of time, even if you sometimes forget to charge between uses.

The Romp Party has long battery life – much longer than typical for a panty vibrator in this price range. It lasted 115 minutes at its highest power during our test, more than twice as long as the comparably-priced VeDO Niki and NS Novelties Techno Lucy (both 55 minutes).

If you want even longer, the Lovense Ferri runs about 2.8 hours at top power. It’s pricier than the Romp Party but is a much better panty vibrator overall.

Romp Party Build Quality

The Ida Wave’s build quality is excellent. I’ve owned my Ida Wave since 2022, and it’s continued to operate as expected. The silicone is smooth, the shiny plastic top has stayed scratch-free with normal use, and the seams between materials are tight. The flex point between the internal and external arms feels solidly built, with no loosening or signs of strain.

The Romp Party’s build quality is decent for the price, but a step behind most panty vibrators I’ve tested. It’s coated in a nice silicone with a slight flex to the core, and the on-toy and remote-control buttons each have a satisfying click feel. The plastic remote feels fairly sturdy too even though it’s quite lightweight.

The weak spot is the magnet that holds the toy to your underwear. It has decent grip when seated, but it protrudes far enough from the toy that it’s easy to knock off by accident – and the same small magnet is what struggles to anchor the long, stick-straight body during heavier movement.
