Couldn't load pickup availability
GammaTune V40 brings the 40 Hz rhythm to touch. Eight soft-tipped arms rest gently around your scalp and deliver steady 40 Hz mechanical vibration, designed to help you relax, relieve stress and support better sleep as part of your daily wellness routine.
Choose from five sensations, from a gentle continuous hum to a slowly rising and falling wave. A built-in 30-minute timer ends each session automatically, so you can simply sit back and unwind during a quiet break or your evening wind-down.
Key Features
- 40 Hz you can feel: All modes use 40 Hz mechanical vibration while active; only the intensity or pattern changes.

- Relax & unwind: Designed to help you relax, relieve everyday stress and support better sleep as part of a calming bedtime routine.
- 30-minute auto timer: Each session ends automatically. Start with 5–10 minutes and build up only if comfortable.
- Eight-point scalp contact: Center over the crown and let the pads rest gently around the scalp, with no pressing required.
- USB-C rechargeable: Rechargeable lithium-polymer battery; charge for about 3 hours before first use.
