The dark grey LA-401 Universal Ear Speaker from Listen Technologies is designed to provide maximum audio quality and freedom of movement without cable snags. The universal style easily fits over your ear and offers a comfortable, secure fit on either your left or right side. The open design allows you to hear direct sounds, as well as enabling you to use the speaker along with hearing aids. It is constructed of hard plastic which can be easily and hygienically cleaned and reused. The speaker can be used with the short-integrated neck loop/lanyard for minimizing cable tangles, or with the included extension cord for concealing your wires in your pocket.
