• If the headphones are in Standby mode but not connected to any A2DP devices, briefly press the
Next button (C) once to connect to the last connected A2DP device.
Near Field Communication (NFC) Operation
Make sure that your mobile phone has the NFC function and the headphones aren't low on power.
Specific NFC procedures can vary among phones: Refer to your phone manual as needed for details.

within a centimeter of the inductive area (K) of the headphones for 3 seconds.
•
To automatically enable the headphones' Bluetooth function, hold the phone (with the NFC
function activated) within a centimeter of the inductive area (K) of the headset for 5 seconds.

About the Battery

•
A new battery attains its optimal level of performance (its ability to fully power the headphones)
only after two or three complete charge and discharge cycles. The battery can be charged and
discharged hundreds of times, but it will eventually wear out.
•
When not charging the battery, disconnect the headphones from any power source. Do not leave a
fully charged battery connected to a charging circuit since overcharging may shorten battery life.
• If a fully charged battery is left unused, it will fully discharge over a period of time. These
headphones will automatically turn off if no devices are connected during wireless operation.
• Leaving the headphones exposed to extremes in temperature for any length of time, such as in a
parked car during summer or winter, will reduce the battery life and capacity. Ideally, the battery
temperature should be maintained at 15-25˚C (59-77˚F).
• As with any batteries, do not dispose of the headphones in a fire or anywhere it could be expected
to catch fire, as the built-in battery could explode.

Operating Tips

If you're unable to connect the headphones to a device:
• Make sure that the headphones are fully charged, switched on, paired with the device and
indicating a successful connection.
• Make sure the device's Bluetooth function is activated.
• Check that the distance between the headphones and the device is no more than 10 m / 33 ft., and
that there are no obstructions such as walls or other active wireless items between two devices that
could interfere with the signal.
•
Bluetooth music devices or Bluetooth / Bluetooth stereo transmitter music devices must support
Bluetooth A2DP and Bluetooth AVRCP.
• If the headphones are paired to more than one device at the same time, they will only connect to
the device with the strongest signal.
• Not all phones feature the function that allows the headphones to be switched from music to
phone calls.
