If a problem occurs…
How can I reset/restart the earbuds?
Answer:
If the functions of the earbuds are disturbed, you will need to perform
a soft reset. A soft reset will be done each time you insert the ear-
buds into the charging case and wait for at least 10 seconds.
How can I perform a factory reset?
Answer:
If the functions of the earbuds are disturbed and a soft reset does not
fix the issue, reset the earbuds to the factory default settings. This
deletes, among other settings, all pairing settings.
You can reset the earbuds to the factory default settings using the
Smart Control app in the settings menu.
To perform a factory reset without the Smart Control app, peer-pair
the 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.
What should I check if my earbuds are Bluetooth connected but
music is not streamed to the earbuds?
Answer:
The CX True Wireless supports two different Bluetooth connections:
Bluetooth audio for all audio connections and Bluetooth Low Energy
for Sennheiser Smart Control app connection.
If your smartphone's Bluetooth menu shows an active connection to
"CX True Wireless" and audio can't be heard with the earbuds, but
still played on the smartphone, you may have only established the
Smart Control app connection.
