green/red?
By default, the left and right earbud are peer paired to each other and
connect automatically after power-on. If the LED indicator is alter-
nating green/red, this earbud is not peer paired, i.e. the left and right
earbuds are not connected to each other.
In this case perform the following steps to pair both earbuds:
1. Make sure that the earbuds are not connected to any Bluetooth
device. Deactivate Bluetooth on your Bluetooth device or delete
“CX True Wireless” from the list of paired devices in the Bluetooth
menu of your Bluetooth device.
2. Charge the right and the left earbud.
3. Take one earbud out of the charging case.
The LED of the earbud lights up red.
4. Press and hold the touch control panel for 10 seconds until you
hear the voice prompt “Pairing” and a beep sound.
The LED of the earbud flashes green and red. The earbud is in ear-
bud pairing mode.
5. Now take the second earbud out of the charging case and make
sure that the right and the left earbud are close together (max.
distance 50 cm).
6. Press and hold the touch control panel of the second earbud for
10 seconds until you hear the voice prompt “Pairing” and a beep
sound.
If pairing was successful, you hear the voice prompt “Pairing suc-
cessful” and the LEDs of the earbuds flash blue 3x. The earbuds
are paired with each other and the factory default settings are
restored.
Now pair the earbuds with your Bluetooth device.
Are there reasons why the earbuds may not recharge as usual?
Answer:
Ensure that the charging contacts of the earbuds and the charging
case are clean. If charging is still not possible, perform a reset and a
factory reset of the earbuds.
How can I adjust the earbuds to a comfortable volume or make
them louder?
Answer:
For some Android smartphones there is a separate volume control
for the Bluetooth headset and for the Android smartphone. Ensure
that both volume controls are set to max. To increase volume, tap
and hold the touchpad of the right earbud until you hear the voice
prompt "Volume max". Now increase the smartphone's volume to
maximum volume.
For smartphones that feature "absolute volume control" such as the
Apple iPhone, there is only one volume control available, so you can
either use the volume control of the smartphone or that of the CX
True Wireless. With a few smartphones "absolute volume control" is
not available by default but can be activated within the development
options.
