Connecting the earbuds to a Bluetooth device

To be able to use the Bluetooth wireless connection, you must register both devices (earbuds and e.g. smartphone) via the device settings of your smartphone. This process is called pairing.

If operation differs from the steps mentioned, also refer to the instruction manual of the Bluetooth device you are using.

When you switch on the earbuds for the first time after initial charging, they automatically switch to Bluetooth pairing mode.

Information on the Bluetooth wireless connection

The earbuds are compatible with Bluetooth 5.2.

If your audio source supports one of the following high-resolution audio encoding methods, music is automatically played in high audio quality: aptX®, aptX adaptive® or AAC. Otherwise the headphones will play your music in normal audio quality (SBC). The used audio coding is displayed via the Smart Control app.

Paired devices establish the Bluetooth wireless connection immediately after switch-on and are ready for use.

When you switch on the earbuds, they automatically try to connect to the last connected Bluetooth device. The earbuds can save the connection profiles of up to six Bluetooth devices with which they have been paired. Audio playback is only possible from one device at a time.

If you pair the earbuds with the seventh Bluetooth device, the saved connection profile of the least used Bluetooth device will be overwritten. If you want to re-establish a connection with the overwritten Bluetooth device, you have to pair the earbuds again.

Using the Smart Control app, you can view the list of paired devices and selectively connect and disconnect devices ("Connections").

Paired and connected Bluetooth device
Paired Bluetooth device (currently not connected)

The right and the left earbud also use a Bluetooth wireless connection. Both earbuds are paired with each other upon delivery. If you are using a different earbud (e.g. a spare earbud), the two earbuds must also be paired with each other.

Pairing the earbuds with a Bluetooth device

1. Take both earbuds out of the charging case and insert them into your ears. The distance between the earbuds and the Bluetooth device should not exceed 40"/1 m.
2. Simultaneously touch and hold the right and the left touch control panel for 3 seconds until you hear the voice prompt "Pairing" and a beep. The LEDs of the earbuds flash blue and red. The earbuds are in pairing mode.
3. Activate Bluetooth on your Bluetooth device.

Leaving the Bluetooth transmission range
Wireless calling and streaming are only possible in the Bluetooth transmission range of your smartphone. The transmission range largely depends on environmental conditions such as wall thickness, wall composition etc. With a free line of sight, the transmission range of most smartphones and Bluetooth devices is up to 10 meters.
If you, and therefore the earbuds, leave the Bluetooth transmission range of the smartphone, the sound quality deteriorates increasingly until you hear the voice prompt "No connection" and the connection breaks down completely. If you immediately re-enter the Bluetooth transmission range, the connection is automatically re-established and you hear the voice prompt "Connected". If this is not the case, tap the touch control panel of the earbud 1x.

Resetting the earbuds
If the function of the earbuds is disturbed, perform a reset. Individual settings such as the pairing settings are not deleted.

• Insert the earbuds into the charging case and close the lid. After 10 seconds, the earbuds will restart (reset).
  

Resetting the earbuds to the factory default settings
If the function of the earbuds is disturbed and a reset does not improve, reset the earbuds to the factory default settings. This deletes, among other things, all pairing settings

The easiest way to reset the earbuds to the factory default settings is using the Smart Control app.

Alternatively, you can manually proceed as follows:

1. Deactivate Bluetooth on your smartphone.
   The connection between your smartphone and the "MOMENTUM TW 3" is disconnected.
2. Take one earbud out of the charging case, leave the other earbu din the charging case.
3. Touch and hold the touch control panel of the earbud that is no tin the charging case for 10 seconds.
   The LED on this earbud alternately lights up green and red.
4. Now stop touching the touch control panel.
5. Place the earbud back into the charging case. Be sure to leave th elid of the charging case open when doing so.
   After 20 seconds, the earbuds are reset to the factory default settings and automatically reconnect to each other.

After the earbuds have been successfully reset and paired with each other, the LED of the charging case lights up red and green 3x.

• To reconnect your earbuds to your smartphone, reactivate Bluetooth on your smartphone.

Pairing a spare earbud with another earbud
The right and the left earbud are paired with each other upon delivery. If, however, you are using a different earbud (e.g. a spare earbud), you have to pair the two earbuds with each other once. This pairing process resets the earbuds to the factory default settings.

1. Insert both earbuds into the charging case and leave the lid of th echarging case open.
2. After 20 seconds, the earbuds are paired with each other.
   The LED on the charging case then lights up red and green 3x.
   The earbuds are now paired with each other.

If you have closed the lid of the charging case too early, repeat the above procedure.

After the pairing process with a spare earbud, all settings are reset. Pair the earbuds with your smartphone again
