With or Without Hearing Aid

The Domino Classic Personal Listening System is designed both for non-hearing instrument users and hearing instrument users (with "T" position) and delivers crystal-clear stereo sound, free from background noise and feedback. Range: 75 feet line of sight (indoors).

Easy to Use

Domino Classic's unique design makes use very intuitive. All common features can be accessed with a single push of a button, eliminating complicated menus.

How Domino Works

The Domino Classic system consists of a transmitter and receiver equipped with state-of-the-art microphones. Sound is picked up both by the remote transmitter and receiver microphones and converted into digital data.

Speech is clarified and annoying background noise is eliminated. The transmitter sound is streamed over an encrypted wireless link to the receiver for listening with earphones, headphones or neckloop. The transmitter also incorporates a stereo input for streaming high quality audio from your TV, MP3 player or stereo system. From the receiver, you can easily control the functions of the two units. This eliminates the need for a distant transmitter when you want to change a listening function.

For various users and user situations:

Domino Classic is designed to help people with both mild and severe hearing loss overcome difficult listening situations: school classrooms, at home, watching TV, meetings/seminars.

Hearing instrument users with a built-in telecoil ("T" position) may use Domino Classic as a remote and amplified microphone. The amplified sound in Domino Classic is discreetly transferred to the hearing instrument via the neckloop.

Users without hearing aids can choose to listen with headphones, stetoclips or earbuds.
