These are the rechargeable in-ear hearing aids with simple buttons for easy adjustments. Unlike similar models that cost three or four times as much, these units have active noise reduction to minimize non-voice sounds such as air conditioners, fans, and traffic and four different environment settings (standard, restaurant, outdoor, music). The hearing aids also have a discreet in-canal design that allows them to be discretely worn. With six volume settings. Includes two hearing aids and three pairs of different sized tips. A full charge using the included case provides up to 12 hours of power. Case plugs into USB.
