Telecoil technology is a widely used standard in hearing aids that enables users to collect sounds from special sources and fields, canceling environmental background noise. NoiZfree-Telecoil is a lightweight series of hands free and audio-phones for telecoil compatible hearing aids, placed behind the ear. Simply switch the hearing aid to T-function (or MT in some devices) and place the ear-hook on the ear. Four different types provide different options to users to enjoy noise-free use of mobile phones, intercoms, dect phones and audio sources (HiFi, portable walkman, cd players, mp3 players, etc.)
Measures 34, unstretched. Includes color or shirt clip and on/off button on the cord.
