Yes. The device can be connected to non-Bluetooth enabled devices (such as a MP3 player) using the supplied 3.5mm audio cable.

Insert one end of the cable to the round jack of the device; and the other end of the cable to the headphone jack of the non-Bluetooth enabled device.

Tip:
This connection is especially useful when you are in an airplane where Bluetooth connection might be prohibited.

Tip:
No battery power is required when you use the headset with the audio cable.
