Connected Dual-Motor Sonic Wave Masturbator — F1S V3 Teal

Lelo's third-generation F1S retains what the model is known for: SENSONIC technology, which sends low-frequency sound waves into the sleeve in addition to classic vibrations. Cylindrical black casing with a transparent window on the teal sleeve, Bluetooth app to customize all modes.

SENSONIC: Sound waves that penetrate matter

This is what sets the F1S apart from classic vibrating masturbators. A second motor sends sound waves (audible to the body, not the ear) into the silicone sleeve. These low frequencies penetrate tissues more deeply than mechanical vibrations alone — you feel the stimulation inside the glans and all around, not just on the surface. The result is similar to an internal massage that other masturbators do not produce.

Ten internal sensors to measure your use

The sleeve contains ten SDK sensors that measure the pressure, speed, and frequency of your movements in real-time. The Lelo app displays the data during the session, allowing you to adjust the mode to match your rhythm. Cruise Control mode maintains stable intensity even when you clench — useful for edging phases where you want to maintain consistent stimulation.

Bluetooth app to create your own profiles

Via the Lelo app (iOS/Android), you can control the two motors independently — vibration only, waves only, or both in parallel at different intensities. You can also save your favorite settings, which prevents you from always falling back on the same factory mode. Manual mode is accessible without the app via the physical buttons on the casing if you prefer to disconnect from screens.

Removable medical-grade silicone sleeve for cleaning

The teal sleeve detaches from the casing for thorough rinsing with lukewarm water — non-porous medical-grade silicone material, easily sterilizable, resists aging without becoming sticky. The casing itself recharges via a magnetic connector (cable included), with approximately two hours of battery life in normal use. Soft-touch matte finish that holds well in hand even when lubricated.
