This is the only in-ear Bluetooth device that uses bone conduction and sound recognition technology to detect snoring and alert the wearer to change positions. The device is made with soft silicone, comfortably fits over an ear, and can be set to employ beeps or one of 54 vibration levels that gently stimulate the body to shift position, disrupting snoring. It also pairs with an Android/iOS device via Bluetooth and records sleep data on a free app. A two-hour charge using the included USB cable provides power for up to two nights. Includes one earpiece.
