Q: Why aren’t my ULTIMATE EARS BOOM controls working correctly when I use a 3.5mm auxiliary cable?

A: The ULTIMATE EARS BOOM was designed to be used with a 3-pole (non-microphone or inline remote cable) auxiliary connector.

You may experience unexpected behavior with controls if you use a 4-pole (with inline microphone and/or inline remote) auxiliary cable. Only use a 3-pole cable with your ULTIMATE EARS BOOM.
