The included WM O8 wireless module receives wireless audio to improve fast and clear audio without any delay. It must be paired to the Equinox 800 before it can operate. It doesn’t have a speaker so headphones must be used with the module, but the connection jack is 1/8”. You’ll need an adapter if you’re using ¼” headphones. The module allows you to use your choice of headphones or ear buds, and since the module can be clipped to your side, wired headphones will not inhibit detection as it’s not physically connected to the detector.
