To use the EP634 as a pair of wired headphones, use a 3.5mm
audio cable to connect the EP634 to your source device. Once the
audio cable is connected to the EP634, the device automatically
switches to wired mode. The headphones do not need to be
switched on for wired mode and the microphone and control
buttons are disabled.
