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.

In the next sections, I’ll cover the Niki’s vibration power and rumbliness in-depth.

Here’s the main conclusion:

The Niki is one of the most stimulating panty vibrators and one of the few I can orgasm with hands-free. It’s strong, transfers the vibes where they should go, and is the most rumbly panty vibe I’ve tested. If you value raw power most, go with the stronger Lovense Ferri. If strong, rumbly vibrations matter more, go with the Niki.

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.

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.

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.

The Niki’s clit motor hits a top power of 8.0 out of 10 – great power, but not the strongest panty vibrator out there. Both the Lovense Ferri and NS Novelties Techno Lucy are stronger on high power, though both are also noticeably buzzier than the Niki. Where the Niki stands out isn’t raw power, though – it’s that the broad, flexible, curved design delivers that power to your body unusually well – essential for good stimulation in a hands-free toy. Among panty vibrators, only the Ferri transfers more of its motor’s strength to the clit.

For me, the Niki’s 8.0 top strength is enough power to orgasm hands-free. If top vibration strength is your main priority, go with the Ferri – but the Niki is plenty powerful for most people.

The Niki has six power levels spanning a wide range, from a very gentle 1.0 for warmup up to 8.0 at the top. That low end matters more with a wearable than with a handheld because you can’t just lift a panty vibrator off your body when things start feeling too intense – it’s nice to be able to dial down without reaching to pull the toy out of place.

Vibration transfer is where the Niki really stands out from most panty vibes. With a handheld you can position the vibrator exactly where you want it and just press harder to make the vibes feel more intense; with most wearables, you can’t, so the toy’s shape has to naturally transfer the vibrations where they should go. And the Niki’s shape does that well – its broad, flexible, curved design stays consistently in contact with my body transferring the vibrations right to my clit.

I wear it two different ways: with the top near my clit and the back end toward my vagina, or my preferred “upside-down” way with the top just under my clit and the rest of the toy wrapped up around my pubic bone. The vibrations transfer really well either way, but the toy stays even tighter to my body with the upside-down method.

The Niki’s curve also lets you press harder when you want to for more stimulation – something flat panty vibes can’t do. When you’re sitting, you can shift your weight against the end of the toy that’s opposite your clit. The surface pushes against the base and the curve tilts the clit end to press more firmly into you making the vibes feel stronger. It’s the closest a hands-free wearable gets to the better pressure control of a handheld.

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.

We rate rumbly vibrations higher than buzzy ones because most people prefer rumbly. But it’s a personal preference, and some people like buzzy vibrations more.

The Niki is the most rumbly panty vibrator we’ve tested. Every other panty vibrator I’ve tested – the Lovense Ferri, We-Vibe Moxie+, NS Novelties Techno Lucy, and Romp Party – center around around the moderately or extremely buzzy frequency range. The Niki is the only one with a primarily rumbly clit motor.

The Niki’s lowest settings are extremely rumbly, the middle settings stay moderately rumbly, and only the very top setting feels neutral – never becoming buzzy. All the other panty vibrators we’ve tested become buzzy on their top settings. The Niki’s rumbliness has real power behind it too – the motor is strong as well as deep.

If rumbliness is what you want from a panty vibrator, the Niki is the best choice – no other panty vibrator I’ve tested comes close. If you care more about raw power than rumbliness, the Ferri is excellent – it’s less rumbly, but it’s stronger with excellent vibration transfer, and I can orgasm hands-free from it just as easily as from the Niki.

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.

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:

• best remote and app-controlled vibrators (all types of vibrators)
• best wearable vibrators (wearables only).

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.

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

Here’s the main conclusion:

The Niki has one of the better panty-vibe remotes – reliable connection, quick response, and fast, direct power buttons. Its main limitations are typical of remotes versus apps: less partner feedback and shorter range. Go with the Lovense Ferri for app control, but the Niki has great remote control, which can be nice if you don’t want you or a partner to be tied to a phone.

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.

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.

The Niki’s remote is great with a few minor downsides – most of which are typical of remotes compared to apps.

Power control is fast and direct – you can move forward and backward through the six power levels with dedicated + and – buttons. Pattern navigation uses a single-button cycle loop – clicking forward through the nine patterns one at a time, with no way to go backward to a previous pattern. In practice this doesn’t matter that much, since most people stay on steady vibrations rather than cycling through patterns. You can also adjust the intensity of each pattern.

The remote is comfortable to hold, but the buttons themselves are less tactile than the best panty-vibe remotes – they’re not raised enough to tell which is which by feel, so I have to look at the remote to find the right button – something you get used to as you use the remote more.

Like most remotes, the Niki’s gives your partner just a faint blink when you press a button – no way to tell what setting your toy is on. That’s fine if you’re using the Niki yourself and many partners won’t mind. Others find it less engaging when they can’t tell what your toy is doing and what you’re actually feeling. An app-controlled panty vibe gives your partner real-time visuals of the toy’s vibrations, which makes controlling it feel more engaging. If that’s a priority for you, the Lovense Ferri is the best app-controlled panty vibe, and Lovense has the best app of any brand.

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.

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.

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

Body tissue between a remote and toy is typically the main thing that breaks a remote’s signal during partner control, but the Niki holds up well to this. Our body-interference test simulates this scenario at three progressively challenging angles, and the Niki holds a stable connection through all of them. Our test runs harsher than typical real-world conditions, so partner-controlled play should stay reliable in practice.

Button presses register with barely any delay – the toy reacts the moment my finger leaves the button, keeping the rhythm of play intact. And theres no reconnection routine required when starting to play – the remote is always connected.

The remote reaches about 60 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 this gives you enough flexibility for most activities, and especially any same-room use. If you need an especially long range, many app-controlled toys stay connected farther – for instance, the Lovense Ferri stayed connected until 190 feet in our same test.

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.

Like most wearable vibrators the Niki’s on-toy controls are limited by design, since you’ll typically use the remote to control it. There’s a single button that cycles through a steady vibration and nine patterns – all at one fixed intensity. To use the toy’s full six-level power range, you need the remote.

The button itself has a subtle feel and sits further back on the toy, so it takes some reaching to press if for some reason you want to change settings without the remote. When you do press the button, the toy’s broad, flexible shape keeps the pressure comfortable against your body. The on-toy button works as a backup, but the remote is the main way you’ll use the Niki.

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.

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.

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.

In my experience the Niki stays securely in the ideal place when wearing it in bed and during normal everyday activity like walking or going up and down stairs – but it shifts more during heavy movement like running or jumping.

The Niki’s broad, flexible, curved design contours to your body, so it stays snug and doesn’t shift during light activity the way some slimmer or straight panty vibrators can. It’s also secured to your underwear by a magnet – essential for any panty vibrator to fit securely. The Niki’s magnet is on the weaker side compared to other panty vibrators, but in normal wear that’s not really an issue – the form-fitting shape prevents the kind of shifting, tilting, or movement that would pull the magnet off, and the magnet itself is slim and form-fitted to the toy so it doesn’t get bumped off easily. The magnet can come loose when you actively re-position the toy in your underwear, but otherwise has stayed attached for me.

Heavy activity is not as good. When running, the toy bounces on landings and the stimulation briefly pulls away before gravity returns it. With jumping jacks, it slid further down in my underwear, and I had to adjust the placement afterward. It never fell out, but during vigorous movement the form-fitting shape can’t fully prevent the toy from shifting, and the relatively weak magnet doesn’t pick up the slack the way a stronger one can.

If you specifically want a panty vibrator that holds securely under intense movement, the NS Novelties Techno Lucy holds up better. Otherwise, the Niki’s fit is reliable for the way most people will actually use it.

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.

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.

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 Niki is one of the most comfortable panty vibrators I’ve tested, and the comfort holds up just as well when I’m moving around as it does lying in bed.

That’s less common than you’d expect. Most panty vibrators are noticeably less comfortable during light activity than lying down – mostly because toys can poke or apply uneven pressure when walking – but not for the Niki. The Niki’s broad, flexible, curved shape distributes pressure evenly across my body, so there’s no digging in, no pinching when I close my legs, and no uncomfortable tapping when I move. It blankets the area rather than pressing into a single spot.

One wear note: I find the Niki most comfortable when worn upside-down (so the charging port end is facing upward), with the toy’s curve wrapping up around my pubic bone. The reverse orientation is still great, but “upsidown” is slightly more comfortable and stimulating for me.

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.

The VeDO Niki is a very quiet panty vibrator – one of the areas it outperforms the Lovense Ferri a bit. Decibel readings on both low and high power were too quiet for our Sound Level Meter to pick up on – the ambient room noise was 35 dBA, and the Niki never measured higher than this.

It’s in the most discreet group of wearables I’ve tested 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). My partner couldn’t hear the Niki at any vibration strength under any of our three tested volumes of background noise. It is definitely audible in our room without any background audio playing – but every wearable vibrator I’ve tested is audible in a fully silent room, no matter how gentle and quiet its vibrations are.

For our closed-bedroom-door test, my partner stands directly outside the bedroom 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 the toy or move it around – holding it instead of wearing it gives us the most conservative results. My partner couldn’t hear the Niki on its low or middle power levels. He could just barely hear it on high in our completely silent house – pretty faint, and easily masked by cars passing by outside. When I re-checked while actually wearing the Niki, the sound was significantly dampened and he couldn’t hear it on any setting.

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.

The Niki has a short battery life. It lasted 55 minutes continuously running at its highest power during our test – below the higher-end panty vibrators. Since you’ll use the Niki’s lower power levels too, your real-use runtime will likely be longer.

If long battery life is a priority, go with the Lovense Ferri – it lasted 168 minutes during our test, about three times the Niki’s runtime.

The Romp Party is easy to clean. It’s fully waterproof – rated IPX7, so you can rinse it under a running faucet or fully submerge it without worry.

Cleaning the Niki is straightforward in practice, but our rating is conservative because we couldn’t confirm the toy’s exact waterproof status. VeDO lists it as “splashproof – suitable for shower” on their site, which usually corresponds to an IPX5 or IPX6 rating. Products with those ratings are safe to clean under a running faucet or use in the shower, but IPX4 products (which are also sometimes called “splashproof”) are not. We emailed VeDO to confirm the exact IPX rating and didn’t hear back, so we rated the Niki’s cleaning based on not being able to run it under a faucet.

In practice I do run most of the Niki under a faucet without being especially careful, just keeping water away from the charging port and wiping that area with a cloth. I haven’t encountered any issues.

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.

The Niki feels well-built. It’s coated in smooth silicone with a small plastic section around the charging port, and the toy’s slight flex feels sturdy and adds to its comfort. I’ve had mine since 2021 and it’s continued to operate as expected. The plastic remote is very lightweight and cheap-feeling, but it functions well.
