Buying Guide

    Check your device port. Most use a phone jack. Make sure it fits tight.

  • Wire Strength
    Pick a thick wire. It will not break fast. It lasts a long time.

  • Power Source
    Some use a lighter plug. Others tap into the mirror. Choose the best way for you.

  • Mute Button
    Some cords have a small button. Use it to stop sounds. It is easy to reach.

  • Fuse Safety
    Look for a built-in fuse. It stops big surges. This keeps tools safe.
