Review: Colis arrivé ouvert. plus de casque. retourné au fournisseur. dommage. déçue. Etiquette sur le colis mentionnant qu'une batterie est à l'intérieur : ça attire les voleurs. Review: Sleek, compact and easy-to-use digital playback device. Comes with pocket-size hardshell carrying case. Hit the play button and you'll hear a brief voice announcement followed by one hour of the tone. Then it stops. There are also buttons for "back to the beginning" and "jump to the end". Holding the play button down shuts off the unit. 40Hz buzz tone sounds the same a the one posted on Youtube as "Exact 40 Hz Gamma Brainwave audio used by MIT" study. Recharging off a laptop USB port (cable included) is easy and just takes a few minutes to charge. Charging cable plugs into the earphone jack on the unit, keeping it small and simple. Ear buds are good quality, but don't come with alternate size ear pieces, and may be too large for some people. Note that, contrary to the instructions, ear buds are interchangeable--there is no Left ear or Right ear shape. All in all, a very nice design, well-made. ## Features - 40Hz Gamma Waves for Memory - Emits precisely tuned 40Hz gamma frequency tones.

Is it more of a hum or a buzz, or a clicking noise. Does the device have volume control?** A: Thanks for your questions. Our device makes a "clicking" or "fast ticking" sound. The device does have volume control for your desired comfort level. **Q: can device be used while other sound is running ?** A: Yes, I have done that with a secondary source, but not by routing the sound through the Gamma Clarity. I re-read the instructions and while they don't specifically say it's not possible, they also don't explain how it could be done. Visually inspecting the device, it doesn't seem possible to route external sound through the Gamma Clarity. There is one opening and it's used for the headphones. That same opening is used, at other times, to recharge the battery. **Q: Seller... my device turns off after a few seconds and flashes red six times I can restart it but issue repeats how do I fix it?** A: There is something you can do to try to “wake it up”. Press and hold the play/pause button for 90 seconds and see if the light comes on. If the light comes on, you can let go of the button, then push it again for 3 seconds to turn it off. Then turn back on and use as normal. Sometimes when connecting to a charger if you are pushing multiple buttons it can get stuck in a programming mode and this is the only way to get it back out. If that doesn't work, there's one additional thing you can try. There is a hidden reset button on the device. You'll need a small paperclip or sim card pin to press the button. You'll push/hold the button for 30 seconds. Don't do anything else then take it straight to the charger for 24 hours. **Q: Do you use this in conjuction with the lights or separately? Also, can this be plugged in and used instead of relying on the rechargeable battery?** A: Use with light 15 minutes to an hour a day.. great results. Have to recharge with computer. ## Customer Reviews ### ⭐⭐ Review *by G***L on 30 June 2023* Colis arrivé ouvert. plus de casque. retourné au fournisseur. dommage. déçue.
