Featuring a comfortable, over-the-ear design, the LA-401 Universal Ear Speaker offers high-quality audio performance and freedom of movement. The speaker’s open design allows the wearer to hear outside sounds as well as the transmitted audio, and the unit can be used with hearing aids for a truly universal solution.

The LA-401 can also be used with the integrated neck loop/lanyard, and can be worn around the neck, on a belt clip, or concealed in a pocket and connected with the included 3.5mm extension cable.

Each unit has a hard plastic construction that makes it durable and easy to clean using a Listen Technologies disinfecting wipe (LA-901 or LA-902).
