      Widex TV-Dex Wireless TV Streamer

      One year manufacturer warranty. Online ordering availabler. Enjoy distortion-free wireless transmission of TV-sound directly to your hearing aids.


      The Widex TV-DEX is your user-friendly wireless assistive listening device specifically designed for enjoying TV and audio. The main advantage of the TV-DEX is its real-time high-quality stereo sound. Experience TV or audio sound exactly as it was intended – without annoying distortion or more importantly – echoes.


      Another unique feature of the Widex TV-DEX is the ‘Room Off’ function. It allows you to temporarily switch off  the hearing aid’s microphone and hear the TV sound only. This way you can enjoy your favorite TV programs without unnecessary background noise. Naturally, Room off can easily be switched on and off.

      The Widex TV-Dex is designed to resemble a remote control, owing to a lightweight and small design. Easy to carry and use. The TV-Dex is capable of streaming audio files across different electronic devices up to 10 (30 feet) meters away. 

      Room Off Mode

      The Widex TV-Dex “Room Off” option allows you to temporarily turn your hearing aid microphones off, threby eliminating background noise. All you’ll hear is crystall clear television sound corrected for your hearing loss through your hearing aids.

      The Widex TV-Dex MUST be professionally paired by an authorized Widex dealer to a specific set of Widex hearing aids. 

      TV-DEX transmits audio from the TV (and other audio devices such as a stereo player, MP3, etc) to Widex Hearing Aids in stereo.

      The system includes a base station that accepts direct line input from the TV and one additional audio player, such as a stereo. It wirelessly transmits that input to the controller, which is placed within 1 meter (3 feet) from the wearer’s hearing aids when in use. When not in use, the controller can be inserted back into the base station to be recharged.

      TV signals from the controller are transmitted to the hearing aids through near-field inductive transmission (NFIT). The maximum distance between the TV-DEX controller and its base station is 10 m (about 32 feet), and the maximum transmission distance between the TV-DEX controller and the CLEAR hearing aids is 1 m (about 3 feet).

      An important distinction of the Widex TV-DEX (from many commercial TV viewing devices) is that Bluetooth is not used. Instead, a high-frequency carrier (2.4 GHz) is used to carry the TV signal in a stereo format at 212 kbit/s. This has the advantage of a lower current drain and a much smaller delay. The Widex TV-DEX has the broadest transmission bandwidth on the market from 100 Hz to 11.2 kHz. It allows reproduction of the richest and the clearest sound quality possible. From a speech intelligibility perspective, it facilitates a better transmission of high frequency speech sounds (eg, fricatives) than a transmission system that has a narrower bandwidth.

      To ensure excellent sound quality of the TV signals and perfect synchrony between the visual and auditory signals, “Echo-Free” technology is utilized to achieve a delay of less than 5 ms. To extend the battery life of the TV-DEX, Eco-Tech III technology is used, so one charge lasts for approximately 10 hours of continuous use. This is significantly longer than many other commercial TV viewing devices, which typically last only 5 to 6 hours. The current drain on the hearing aids when receiving TV signals is approximately 1.5 mA.

      The Widex TV-DEX also allows the wearers to control the volume of the TV and the hearing aid microphone separately. In a Room “On” condition, the TV-DEX and the hearing aid microphone are both active to allow hearing of the TV signals as well as any environmental sounds. This will be ideal for TV viewing in quiet. In the Room “Off” condition, the hearing aid microphone is deactivated so only the TV signals are received. This has the advantage of eliminating any influence of reverberation and noise on the enjoyment of the TV signals.

      The Widex TV-DEX yields a significantly better sound quality than many other forms of transmission technologies. It also shows that it improves speech understanding during TV viewing in a noisy environment.
