Audio Boot

An audio boot or audio shoe is an electronic device used by the hard of hearing with hearing aids; hearing aids often come with a special set of metal contacts for audio input. Typically the audio boot will fit around the end of the hearing aid (a behind-the-ear model, as in-the-ear do not afford any purchase for the connection) link these with another device, like an FM system or a cellphone or even a digital audio player.

Famous quotes containing the word boot:

    The best quality tea must have creases like the leathern boot of Tartar horsemen, curl like the dewlap of a mighty bullock, unfold like a mist rising out of a ravine, gleam like a lake touched by a zephyr, and be wet and soft like a fine earth newly swept by rain.
    Lu Yu (d. 804)
