Vibration is sound, so if you want the most powerful vibration, you should expect to hear your vibrator. Of course, a well made vibrator will be quieter at any intensity than a poorly manufactured one. This is an important consideration for many buyers, as a rattling vibrator can be very distracting.
When running at top speed on both motors, FORM 6 is the most powerful cordless vibrator that we've tested, while remaining quieter at any given vibration level than other vibrators available on the market.
LITTLE SOMETHING is the quietest vibrator on the market – it's virtually silent. LITTLE CHROMA is also very quiet. If sound level is important to you, these are two great options.
