Troubleshooting
Problem
Solution
Power is not supplied.
• Charge the product.
Unable to pair.
• Confirm that the Bluetooth device communicates using Ver. 2.1+EDR or higher.
• Place the product and the Bluetooth device within 1 m (3.3') of each other.
• Set the profiles for the Bluetooth device. For procedures on how to set profiles,
refer to the Bluetooth device’s user manual.
• Remove the pairing information for the Bluetooth device then pair the product
with this device again.
• Place the headphones in the charging case and close the cover. Then, take the
headphones out again.
• When switching to a new Bluetooth device, you may not be able to pair because
the previously connected Bluetooth device cannot be disconnected. In such
cases, place the headphones into the charging case (with battery level remaining
for the case) and long touch (about 4 seconds) the touch sensor area on the R
(right) side. The indicator lamp flashes in white. After it flashes in white, long
touch (about 2 seconds) the touch sensor area on the R (right) side. After the L
(left)/R (right) indicator lamps light in red, they turn off and then light in white. If
you remove the headphones from the charging case in that state, the product will
switch to the “searching for devices” state and you will be able to pair with your
desired Bluetooth device. Perform these operations within 30 seconds of placing
the headphones into the charging case.
No sound is heard / Sound is faint. • Turn on the power of the product and the Bluetooth device.
• Turn up the volume.
• Make sure that this product and Bluetooth device are connected by the A2DP (or
audio connection).
• Disable pairing for this product and the Bluetooth device, then pair the product
with this device again.
• Move away from obstacles between the product and the Bluetooth device, such
as people, metal or walls, and place the product and device closer together.
• Switch the sound output of the Bluetooth device to this product.
L (left) and R (right) are not
connected (sound does not come
out from the L (left) side).
• Check if there is no battery level remaining.
• Place the headphones in the charging case and close the cover. Then, take the
headphones out again.
• If they are not connecting even after trying the above, the L (left) and R (right) may
be disconnected. Use the following procedure to connect them manually (this
procedure can be performed only when the L (left) and R (right) are disconnected).
– With the headphones and Bluetooth device disconnected, touch the touch
sensor areas on both the L and R (left and right) sides twice. The indicator
lamps on both the L and R (left and right) sides will change to quickly flashing
in pink, and after a while the indicator lamps on both the L and R (left and
right) sides will slowly flash in white to indicate that the L (left) and R (right)
are connected.
