LELO Siri 2 Sound-Reactive Clit Vibrator

Music moves it: this clit vibrator reads sound through a built-in pickup, so the vibration follows the beat of whatever is playing, or a partner's voice. That is the difference from a unit running a fixed waveform, and eight modes cover the conventional alternative.

The size is the second hard specification: 64 g at 94 x 44 x 32mm, small enough for a pocket without a case. The motor is rated at 120Hz.

Power comes from a Li-Ion 500mA 3.7V cell: two hours of charging for two hours of use, and 90 days of standby, so it does not need charging before every session. The body is body-safe silicone over an ABS core.

FAQs

How does the sound-reactive function work?
A built-in pickup follows what it hears: music makes the vibration move with the beat, and a partner's voice changes it too. The 8 standard modes are there for when you would rather not have sound drive it.

How long does it take to charge, and how long does it run?
2 hours to a full charge at 5.0V, giving 2 hours of use from a Li-Ion 500mA 3.7V cell. The runtime matches the charge time, which is more generous than most in this range.

What is the 90-day standby figure for?
It means the unit holds charge for up to 90 days between sessions, so it does not need a top-up before every use. That is unusual — several models in this range drain noticeably faster when idle.

How big and how heavy is it?
94 x 44 x 32mm and 64g. That is small enough to travel without a case, and light enough not to be awkward to hold.

What is the 120Hz motor rating?
It is the vibration frequency the manufacturer quotes for the motor. In practice a higher frequency reads as a finer, faster buzz rather than a stronger throb.

How loud is it?
The maximum sound level is stated as below 50dB — quieter than normal conversation and among the more discreet models here.

Who is this best suited to?
Anyone who wants the vibration to change with sound, and travellers who value the small size and the 90-day standby. If you want app or remote control, or internal G-spot stimulation, this model offers neither.
