Experience the power of gamma brainwave entrainment with this innovative 40 Hz light and sound device. Designed to induce the gamma brainwave state, associated with heightened focus, learning, and cognitive abilities, this compact gadget emits a bright white light that flashes at a precise 40 Hz (25 ms) frequency, in accordance with MIT research papers. The synchronous 40 Hz audio output further enhances the entrainment effect, creating an immersive sensory experience. Adjust the brightness to your desired level with the convenient knob, and take this pocket-sized device anywhere you go. Powered by 2 AA batteries, it's easy to use anytime. Unlock your brain's full potential with this cutting-edge 40 Hz LED light and sound entrainment device.

NOTE:
This product produces a 40Hz CLICKING sound that is precisely synchronized with the 40Hz flickering light, and is EXACT/REAL 40Hz audio from the MIT research lab that was used in their test trials in their studys. Most of the other youTube videos claiming a 40Hz binaural sound are not matching the MIT researchers' method.
