This is the device that makes cell phone conversations easier to hear by amplifying a call's sound up to 30 decibels. A cell phone connects to the device via Bluetooth, sending calls to the device, where the sound is amplified through an included pair of in-ear headphones. The amplifier's headphones slip around both ears unobtrusively, providing a comfortable fit for the in-ear buds. Worn around the neck using its built-in lanyard, the amplifier has a built-in microphone that picks up the speaker's voice clearly, convenient buttons for one-touch call answering and volume, and a quick-disconnect cable that sends calls back to the phone when desired. The amplifier also communicates with Bluetooth-enabled audio devices for listening to music. Compatible for those using T-coil hearing aids. Its rechargeable battery provides 13 hours of operation from a three-hour charge using either the included USB, AC, or car adapters. 3" L x 1 1/2" W x 3/4" D. (3 oz.)
