Bullet & Mini Vibrator Tests
Vibration Frequency Rumbly or Buzzy

What is it:

How “rumbly” (low frequency) or “buzzy” (high frequency) the vibrator feels. And whether it delivers strong vibrations while remaining reasonably rumbly. Higher scores indicate a “more rumbly” (lower-frequency) bullet or mini vibrator, since the majority of people prefer rumbliness. But ultimately vibration frequency is a personal preference.

When does it matter:

If you prefer vibrations in a specific area along the rumbly-to-buzzy spectrum. Rumbly vibrations spread out more and you feel them deeper. Whereas you feel buzzy vibrations nearer to the surface and more concentrated around the point of contact. Both can feel good, and which you enjoy more is a personal preference.

A bullet vibrator’s frequency affects how its vibrations feel. 

You feel slow, low-frequency, “rumbly” vibrations deeper in your body, reaching more of the internal clitoral network. In contrast, you feel fast, high-frequency, “buzzy” vibrations closer to the surface, concentrated near the point of contact.

Hear the difference in pitch between the rumbly We-Vibe Tango X and the buzzy Satisfyer Ultra Power Bullet 8. These vibrations don’t just sound different – they feel different. 

Both can feel good and which you enjoy more is a personal preference! We measure each bullet and mini vibrator’s frequency at all power levels to help you find a bullet in your favorite range – whether buzzy, rumbly, or somewhere in between! If you don’t know what you like yet, we’ll provide suggestions to help you learn your preferences.

Note, we also test the rumbliness of wand vibrators here.

Test Results Table


  • If you prefer rumbly vibrations, simply choose a bullet or mini vibrator from the table with a high “Rumbliness” and “Overall” score, which indicates good performance in other areas too.
  • If you prefer neutral or buzzy vibrations, look for a bullet or mini vibrator that performs well Overall and has a “Frequency on Median Power” or “Frequency on High Power” that matches your preferred feeling (moderately rumbly, neutral, moderately buzzy, etc.)

You can see all product ratings and filter this table by performance and price using our comparison table tool here.

When It Matters


Vibration frequency always affects your experience with your bullet vibrator. Our bodies’ cells detect and respond to vibrations differently at different frequencies.

We-Vibe Touch X vs Tango X Vibration Power vs Frequency Graph Demonstrating How to Read Rumbliness
Despite being equally powerful, the We-Vibe Touch X and Tango X feel very different because they vibrate at different frequencies. 

You will simply perceive two equally powerful bullet vibrators differently if they vibrate at separate frequencies. 

“Just as the human ear perceives certain frequency sounds to be louder than others, vibrations are perceived slightly differently depending on their frequency. Different mechanoreceptors detect vibration at different frequencies.”

“If we take two motors with the same vibration amplitude but different vibration frequencies the slower motor will produce more displacement. This can have a considerable effect on vibration perception.”

Some people, like me, enjoy a bit of everything. With small vibrators, I often enjoy neutral and even buzzy vibrations most, like the upper levels of the We-Vibe Touch X or Lovense Ambi! But with extremely powerful large toys, like wand vibrators, I often enjoy the more rumbly middle settings of toys like the BMS PalmPower Extreme or Magic Wand Rechargeable.

Others only want vibrations on one side of the spectrum, usually the rumbly side. 

If you have a strong preference, our test results will help you find a good fit. If you know what you enjoy, see the instructions at the top of our Test Results table to help you choose a bullet vibrator that meets your needs.

If you don’t know what you like, I suggest choosing a moderately rumbly bullet or mini vibrator (since more people prefer rumbliness) with some rumbly settings and some neutral or buzzy ones to help you learn your preferences.

The Fun Factory Laya III, We-Vibe Touch X, and Lovense Ambi are a few of my favorite mini vibrators with these versatile frequency ranges. For a more budget-friendly option, the Pillow Talk Racy is also a great choice. 

What We Mean By Rumbly and Buzzy Vibrations


It’s important to understand how we define the terms “rumbly” and “buzzy” and how we measure vibration frequency so you can understand our results.

The term “rumbly” does not have a precise, agreed-upon definition in the sex toy industry. But people typically use the term to describe lower-frequency vibrations that travel deeper into your body. Whereas people use “buzzy” to describe higher-frequency vibrations that remain near the surface. 

But lower or higher than what? 

A bullet vibrator that one person considers “extremely rumbly,” someone else might say is only “moderately rumbly.” This happens for two reasons:

First, everyone has their own frame of reference based on the sex toys they’ve tried. For instance, maybe you’ve only tried buzzy bullet vibrators, so one with neutral vibrations will feel rumbly to you. And second, different people simply perceive vibrations differently!

Our bullet vibrator testing system is designed to solve the first issue by measuring the vibration frequencies of every mini vibrator we test using the same test method. That way, you can always tell whether the bullet vibrator you’re considering is more or less rumbly than another one we’ve tested.

So that our results and language have a consistent, precise meaning, we define the frequency ranges like this: 

  • Extremely Rumbly: Vibration frequency less than or equal to 60 Hz
  • Moderately Rumbly: Vibration frequency greater than 60 Hz and less than or equal to 75 Hz
  • Neutral: Vibration frequency greater than 75 Hz and less than or equal to 90 Hz
  • Moderately Buzzy: Vibration frequency greater than 90 Hz and less than or equal to 105 Hz
  • Extremely Buzzy: Vibration frequency greater than or equal to 105 Hz
Vibration frequency ranges demonstrated with the We-Vibe Touch X’s Power vs Frequency Graph. The Touch X begins extremely rumbly on its lowest levels, then climbs through moderately rumbly middle levels up to its neutral top settings.

These ranges are based on my interpretation of how each frequency range feels. Since people perceive vibrations differently, you may think vibrations at 65 Hz feel extremely rumbly, even though I think they feel moderately rumbly. The purpose of these ranges is to establish consistency – so you can always tell whether the bullet vibrator you’re considering is more or less rumbly than another, regardless of differences in our personal perception.

We provide you with a graph of each bullet vibrator’s frequency range, so you can tell how it feels on every power level. Often a bullet vibrator is rumbly on its gentle settings but neutral or buzzy on the strongest settings. 

We also provide the Median Frequency —this is the part of the rumbly-to-buzzy spectrum that the bullet’s vibrations are centered around, and it gives a quick way to tell how rumbly or buzzy the vibrations generally feel.

Although the Femme Funn Ultra Bullet’s lowest setting feels rumbly, its Median Frequency is 99 Hz (moderately buzzy), so you can expect most of your experience to feel buzzy.

Lastly, we provide a Power and Frequency Balance measure, so you can quickly tell whether a bullet vibrator is both rumbly and strong.

How We Measure Vibration Frequency


When we test a bullet vibrator, we measure the vibration frequency of each power level.

I press the bullet or mini vibrator to my body with the pressure I’d normally apply, record the audio with a mic, and use Adobe Audition to perform an FFT frequency analysis to determine the vibrator’s primary frequency.

Using Adobe Audition’s FFT Frequency Analysis, we determind the frequency with the most energy. This is the bullet’s vibrating frequency. The above screenshot is from the We-Vibe Touch X vibrating on its highest setting. You can see a clear spike at 84 Hz.

Although the mic picks up infinitely many frequencies on any power level, there is a clear spike at the motor’s vibrating frequency. See the image above, which shows the We-Vibe Touch X’s frequency spectrum at its highest power level. There is a distinct energy spike at its vibrating frequency of 84 Hz (5,040 revolutions per minute).

This frequency with the maximum amount of energy is the bullet’s vibration frequency at that power level. We use this frequency as a measure to describe how rumbly or buzzy the bullet vibrator feels at that power level using the frequency ranges we defined above.

Our Test Results & How To Use Them


Power vs Frequency Graphs


What is it:

A graph of each bullet and mini vibrator’s power vs frequency across all of its power levels. 

When does it matter:

If you want a detailed look at the vibrator’s full power and frequency characteristics. This tells you how strong and how rumbly each setting feels. You can also compare two vibrators on the same graph using our graph comparison tool here.

The best way to compare how two bullet or mini vibrators feel is to look at their Vibration Power vs Frequency charts using our graph comparison tool

This example graph shows the Dame Zee and Maude Vibe. Use the full graph tool here to compare any two bullet or mini vibrators.

We use the results of our frequency testing to provide you with this graph of each bullet vibrator’s Power vs Frequency, so you can tell how it feels on every setting. Often a bullet vibrator is rumbly on its gentle settings but neutral or buzzy on the strongest settings.

This graph provides all the essential information about the vibrations: how gently they begin, how powerful they finish, and how each setting feels from rumbly to buzzy.

When using our graph tool to compare bullet vibrators, the product with a vibration profile farther to the left is the more rumbly vibrator. Notice in the graph below that the We-Vibe Tango X and We-Vibe Touch X both reach a vibration power of 7.75. But the Tango X reaches this strength while vibrating at just 58 Hz, which feels extremely rumbly. In contrast, the Touch X (to the right) reaches the same intensity by vibrating at a faster 84 Hz, which feels neutral – neither rumbly nor buzzy.

Some mini vibrators also span a similar frequency range but at different intensities. In this case, both mini vibrators are similarly rumbly or buzzy. But the one with the vibration profile shifted up on the graph is the more powerful vibrator.

In the graph below, see how the Pillow Talk Racy’s and Dame Pom’s frequencies both span from around 48 Hz to 83 Hz. So these mini vibrators feel similarly rumbly. However, you’ll notice the Pillow Talk Racy’s vibration profile is higher on the graph than the Dame Pom’s. So it packs more intensity while remaining just as rumbly as the Dame Pom!

Use these graphs to pick a bullet vibrator in your preferred intensity and rumbliness ranges. Each bullet vibrator’s graph is published in its full review, and you can compare products using our graph comparison tool here.


Median Frequency


What is it:

What part of the frequency spectrum the vibrator’s power levels are centered around. It’s the vibration frequency of the middle power level (the average of the two middle levels if there is an even number of settings).

When does it matter:

If you prefer vibrations in a particular part of the rumbly-to-buzzy spectrum. This provides a quick way to see whether one vibrator’s settings are generally more rumbly or buzzy than another vibrator’s. Since most people prefer rumbly toys, we give higher scores to lower-frequency (more rumbly) vibrators. But ultimately, it’s a personal preference.

The Median Frequency is one of the two measurements we use to rate a bullet vibrator’s rumbliness.

The vibrator’s Median Frequency is the part of the rumbly-to-buzzy spectrum around which the bullet’s vibrations are centered. This gives a quick way to tell how the bullet’s vibrations will typically feel without analyzing its full graph.

For instance, a bullet vibrator with a Median Frequency of 99 Hz, like the FemmeFunn Ultra Bullet (below), is centered around the moderately buzzy part of the frequency spectrum. Although it does have a single rumbly setting (its lowest level), most of your experience using it will feel buzzy. Whether that’s what you want is your individual preference – I love this bullet vibrator personally!

The Median Frequency is also helpful for quickly comparing two bullet vibrators. A bullet vibrator with a high Median Frequency, like the FemmeFunn Booster Bullet (102 Hz – moderately buzzy), generally feels buzzier than one with a low Median Frequency, like the We-Vibe Tango X (50 Hz – extremely rumbly).

Graph Comparison of the Median Frequencies for the We-Vibe Tango X and Femme Funn Booster Bullet

The Median Frequency does not take vibration intensity into account, so it’s also a useful metric to look at if you want a rumbly or buzzy bullet vibrator that provides softer stimulation. Our overall Rumbliness rating rewards mini vibrators that remain rumbly while packing good power. So, looking at the Median Frequency is helpful if you want to separate power from our rumbliness rating.

After you find a few bullet or mini vibrators in the frequency range you like, next check out their vibration power and choose the one with your preferred intensity.


Power and Frequency Balance


What is it:

A measure that rewards bullet and mini vibrators that remain rumbly (low-frequency) while packing good vibration strength. In other words, a bullet vibrator that is strong, but buzzy will perform poorly in this metric. Likewise, a bullet vibrator that is rumbly, but weak will also perform poorly. Only bullet and mini vibrators with strong, rumbly vibrations will have a high rating here. Calculated using the average normalized power / normalized frequency of the vibrator’s settings, with a derating factor applied to buzzy settings. 

When does it matter:

If you want a bullet or mini vibrator with a good balance of power and rumbliness.

This metric tells us which bullet and mini vibrators have both strong power and rumbly vibrations. It’s the second metric we use to rate a bullet vibrator’s overall Rumbliness.

Because the term “rumbly” does not have a universally accepted definition, some people use the term to describe vibrations that are both low-frequency and powerful. People who define rumbliness this way would not consider a gentle 60 Hz bullet vibrator as rumbly as an intense 60 Hz vibrator.

However, we describe both these bullet vibrators as “extremely rumbly” because they both vibrate at 60 Hz (see how we define each frequency range above). We say that one is gentle and rumbly, and the other is intense and rumbly.

But we use our Power and Frequency Balance metric to help you quickly identify the bullet vibrators with good power and rumbliness.

Dame Zee and Magic Wand Micro Vibration Power vs Frequency Graph

For instance, look at the graph of the Dame Zee’s and Magic Wand Micro’s vibrations above. Both mini vibrators’ settings span nearly identical frequency ranges, and their Median Frequency is within 1 Hz of each other. So they both score just as well in the Median Frequency component of our Rumbliness rating.

However, the Magic Wand Micro scores higher in the Power and Frequency Balance component of our rating because it packs much more power while remaining just as rumbly as the Dame Zee! So if you want a powerful, rumbly vibrator, the Magic Wand Micro is the better choice.

We-Vibe Tango X and Femme Funn Booster Bullet Vibration Power vs Frequency Graph

This metric also punishes bullet vibrators that are powerful but extremely buzzy. For instance, see the graph above. Even though the FemmeFunn Booster Bullet is more powerful than the We-Vibe Tango X, it scores lower in the Power and Frequency Balance metric. This is because its strongest settings are buzzy. Whereas the We-Vibe Tango X still packs great power while remaining extremely rumbly.

Remember that this metric is meant to help the people looking for a strong, rumbly bullet vibrator. But if you prefer buzzy vibrations, the FemmeFunn Booster Bullet is the better choice for you, even though it has a lower Power and Frequency Balance rating.

Limitations and Testing Decisions


There are some limitations to using our test results and potential sources of error in our testing process.

The biggest limitation with simply using our Rumbliness ratings to choose a rumbly bullet vibrator is that “rumbly” and “buzzy” are not well-defined, precise terms that everyone agrees on.  

So we may consider some bullet vibrators rumbly that others don’t. When some people say “rumbly,” they only mean that a vibrator is “low-frequency.” Others use “rumbly” to mean that a vibrator is both “low-frequency” and “powerful.” 

We define exactly what we mean by “rumbly” and “buzzy” here, so the terms always have a consistent, precise meaning within our bullet vibrator reviews

We also provide two separate metrics to help both groups easily find a bullet vibrator that fits their needs. We provide the Median Frequency metric (based only on frequency without regard to power) and the Power and Frequency Balance metric (that rewards powerful, rumbly bullet vibrators).

The biggest source of error in the results of our rumbliness testing is that our Power vs Frequency Graphs and our Power and Frequency Balance metric both use vibration power. And while we objectively measure each bullet vibrator’s frequency (how rumbly or buzzy the vibrations feel), we subjectively rate their vibration power (how intense the vibrations feel).

Marked up bullet vibrator graph illustrating which axes are subjectively rated vs objectively measured

How intense a bullet vibrator feels to a person is far more complex than measuring its amplitude and frequency. All of the below (and other factors) affect a person’s perception of how the bullet’s vibrations feel:

  • Vibration amplitude
  • Rigidity or flexibility of the device
  • Motor orientation
  • Weight of the device
  • User age
  • Position of the device on the body
  • Vibration frequency
  • Environmental factors

Essentially, there’s no formula that says, “Because of measurements x, y, and z, this bullet vibrator feels more powerful to everyone than that bullet vibrator.” As a result, we subjectively rate the vibration power, so our power ratings rely on how each mini vibrator feels to me. You can read more about how we test and rate vibration power and its limitations here.

Another testing decision we made that introduces some error is that we press each bullet vibrator to my body when measuring the vibration frequency. 

When the mini vibrator is pressed against you, it transfers its energy to your body. Since it’s losing energy to you by vibrating your body, the vibration frequency is lower than when held in the open air. But we chose this method because the measurements we obtain are more realistic to how the bullet vibrator actually feels. When you’re using the vibrator, you’re pressing it to your body! The vibrating system includes both the vibrator and you

Video demonstrating that when pressing a bullet vibrator to your body, the frequency is lower than when it’s vibrating in the air.

However, the measurements are sensitive to how much pressure I apply when pressing the bullet against my body (though typically only by a couple of Hz). To minimize this sensitivity, I try to keep the pressure applied between different mini vibrators as consistent as possible, and press how I would during normal use. But surely there are some slight variations in the results from this testing choice.

Final Thoughts


There are several great bullet and mini vibrators with deep, rumbly vibrations. But ultimately, the choice between a rumbly or buzzy vibrator is a personal preference. Here are some great options depending on your taste:

Excellent rumbly bullet vibrators:

Excellent buzzy bullet vibrators:

If you’re unsure which you like, choose a mini vibrator with a versatile frequency range not too far to either side of the spectrum, like the Fun Factory Laya III, the We-Vibe Touch X, and the Lovense Ambi.
