These are the world’s first Bluetooth earbuds that use hearing aid technology to clarify voices and dialog. They use proprietary technology that isolates voice frequencies, lifting dialog audio without increasing background noise or music. The earbuds also apply active noise cancelling technology that senses disruptive low-frequency noise and generates a countering sound pattern to reduce ambient noise by 23 decibels. They have a Bluetooth range of 33' and a built-in microphone that enables the earbuds to be used for handsfree calls. Includes three sets of ear domes that accommodate different ear sizes. A full charge via the case provides up to 4 hours of power (case charges earbuds four times before needing a recharge itself). Case charges via USB. Case 2 1/2" W x 1" H x 2 1/2" D. (2 oz.)
