Brand new with all the accessories in retail packaging. The rechargeable Bluetooth Cell Phone Amplifier makes it easy to hear incoming cell phone calls, with or without your hearing aid. Simply pair it with your smartphone and use it as a handset. There’s no more straining to hear, thanks to adjustable tone control plus amplification that’s up to 100 times louder (40dB) than your phone. A built-in "T-coil mode" allows t-coil users to hear the call in their hearing aid without sound from the speaker. Works with all iPhones, Galaxies and other Android phones.
