We Tested 5 Suction Toys with a Real dB Meter. Here's What We Found.
You've seen the listings. Every product claims to be "whisper-quiet." But what does that actually mean when you're sharing walls in a Singaporean HDB flat, and it's midnight?
We decided to stop guessing. We bought four of the most popular suction-style personal massagers available in Singapore -- the ROMP Shine X, ROMP Kiss, LELO Sona 2, and Womanizer Premium 2 -- placed a sound level meter right next to each one, and recorded the real decibel readings. Watch the test below, then read the full breakdown.
The Experiment
The Real Numbers: How Loud Are They?
Each toy was tested at its highest setting, held next to a sound level meter app at a standardised distance. Here's what the meter actually read -- no estimates, no marketing copy.
ROMP
Shine X
Audible through a closed door. The Shine X is powerful but noticeably louder than the others -- closer to a loud conversation than a quiet hum.
ROMP
Kiss
Better than the Shine X but still in "clearly audible" territory. The egg-shaped Kiss is quieter by a few dB -- meaningful, but still not HDB-discreet.
LELO
Sona 2
Despite LELO's premium positioning and "sonic" marketing, the Sona 2 measured nearly the same as the ROMP Kiss. Sonic waves aren't automatically quieter.
Womanizer
Next Liberty
Experience pleasure in silence with the Womanizer Next Liberty, perfect for those who appreciate luxury and discretion. Its whisper-quiet technology offers deep, satisfying sensations without drawing attention. Equipped with a hygienic magnetic cap and USB-C charging, it’s lightweight and easy to store in a handbag or drawer. Embrace the discreet sophistication of the Next Liberty and elevate your intimate moments anytime, anywhere.
Womanizer
Premium 2
The clear winner. Nearly 10 dB quieter than the ROMP Shine X -- and since dB is a logarithmic scale, that's perceived as roughly half as loud. Genuinely discreet for shared living.
Why dB(A) matters: The A-weighting (dB(A)) measures noise the way human ears actually perceive it -- giving more weight to mid frequencies that we're most sensitive to. It's the most relevant measurement for "will my neighbour hear this through the wall."
Context
What Do These Numbers Actually Mean?
Decibels are logarithmic -- a 10 dB increase is perceived as roughly twice as loud, not a little louder. Here's how our tested products map against everyday sounds:
dB Reference Scale
At 53 dB, the Womanizer Premium 2 sits between a quiet room and a normal conversation -- audible up close, but not through a closed bedroom door in a typical HDB flat. The other three, at 60-63 dB, are in the range of a normal conversation and will likely be heard in adjacent rooms.

Beyond the noise test -- here's how each toy actually performs for everyday use in Singapore.
2nd Quietest
Womanizer Next Liberty
Living in an HDB flat or condo means thin walls and close neighbours — privacy matters. That's why the Womanizer Next Liberty is the second quietest pleasure device in our collection, tested on camera at just 56 decibels. That's quieter than a normal conversation, and with a fan or air-con running, it disappears completely. The secret? Contactless 3D Pleasure Air technology — gentle air pulses instead of a buzzing motor. No rattle, no hum through the wall. Just uninterrupted, worry-free me-time. Don't just take our word for it — watch the 56dB reading in our video.
★ Quietest Pick
Womanizer Premium 2
The undisputed winner of our noise test, and it's not particularly close. The Premium 2 uses Womanizer's Pleasure Air technology -- air-pressure waves rather than direct vibration -- which is fundamentally quieter by design. But the feature that puts it in its own category is Smart Silence: a proximity sensor that switches the motor off the instant the toy isn't in contact with skin. Zero noise when you're not using it. The device only activates on touch, so there's no motor running while you're adjusting position, fumbling for a remote, or setting it down.
It also has 12 intensity levels, meaning you can start very gentle and build up -- you're unlikely to ever need max power, where the noise is slightly higher. At mid-range settings the real-world noise is even lower than our 53 dB max test.
3rd
ROMP Kiss
The ROMP Kiss is the most affordable suction toy in our test, and its egg-shaped body is one of the most ergonomic to hold. At 60 dB it was the second quietest -- a couple of decibels below the LELO Sona 2, which surprised us. For couples who are budget-conscious and sharing a space, this is the better-value choice between the two ROMP models. That said, 60 dB is still clearly audible in a quiet room, and in an HDB setting it would carry to adjacent areas.
4th
LELO Sona 2
This is perhaps the most interesting result of the whole test. The LELO Sona 2 is marketed heavily around its "sonic waves" -- a technology that LELO positions as more advanced and more discreet than conventional vibration. Our meter said otherwise: 61 dB, essentially the same as the ROMP Kiss and noisier than its premium price tag would lead you to expect. The Sona 2 is genuinely good at what it does -- the sensations are distinctive and many users prefer them -- but if you're buying it specifically for quiet operation, the data says you'd be better served by the Womanizer.
Loudest Tested
ROMP Shine X
The ROMP Shine X is the loudest of the four at 63 dB -- the same range as a normal face-to-face conversation. That doesn't make it a bad toy (the sensations are intense and the build quality is solid), but if noise is a priority in your purchasing decision, this is the one to deprioritise. On its lower settings the noise is more manageable, which is worth noting if you tend to use toys at mid-range intensity.

Bottom Line
Our Verdict
We tested four of the most popular suction toys available in Singapore with a real sound level meter. The results were clearer than expected: the Womanizer Premium 2 is in a different noise category from the rest, and Smart Silence makes its real-world discretion even better than the dB number alone suggests.
If quiet operation is your top priority -- and in Singapore's high-density housing it often should be -- the Womanizer Premium 2 is the only suction toy in this comparison we'd call genuinely HDB-safe.
