What is the Unisar DH900 TV Listening System?

The Unisar TV Listening Device is a TV amplifier hearing aid device that amplifies sound via a 2.4 GHz radio frequency. This allows the hearing impaired to better hear their television or music player. This device includes a charging base and a stethoset-style headset that receives crystal-clear sound. It also features volume, sound balance, treble, and tone controls so each user can receive sound catered to their individual needs. In addition, both mono and stereo functions are available. This Assistive Listening Devices conveniently comes with two rechargeable batteries so users can always have a battery on hand.

In addition to these basic features, the Unsisar DH900 TV amplifier is built for user comfortability and convenience. The headset is wireless, so users don't have to remain tethered to one spot while watching television or listening to music. There is also a mute button and an integrated microphone that allows users to hear conversations in the room. When the mute button is pressed, the internal microphone is automatically turned on for external voice amplification. This makes switching between conversation and television watching a much more fluid and simple process. The 2.4GHz wireless Unisar DH900 TV amplifier listening system levels the playing field and allows users to comfortably watch television with loved ones while remaining courteous of other's volume level needs, so it is a perfect Daily Living Aid option for the hearing impaired and elderly users with age-related hearing-loss.
