6  |  MOMENTUM True Wireless

If you see SBC rather than aptX, then MacOS does let you change the 
codec via the “Terminal” app. Open Terminal and copy in this instruc-
tion:

sudo defaults write bluetoothaudiod "Enable AptX codec" -bool 
true

Should you prefer to use the AAC codec, just replace “aptx” with 
“aac” in the above instruction.

Please note that you will need to enter your admin login data to 
change these settings. 

If a problem occurs…

How can I reset the earbuds?

Answer:

If the functions of the earbuds are disturbed, you will need to perform 
a manual reset:

Use the USB cable to connect the charging case to a power 
source.

Insert the earbuds into the charging case and, within 60 seconds, 
touch and hold the right and the left touch control panel for 6 sec-
onds simultaneously.

This will restart your earbuds.

How can I perform a factory reset?

Answer:

If the functions of the earbuds are disturbed and a manual reset does 
not fix the issue, reset the earbuds to the factory default settings. 
This deletes, among other things, all pairing settings.

Use the USB cable to connect the charging case to a power source.

Insert the earbuds into the charging case and, within 60 seconds, 
touch and hold the right and the left touch control panel for at least 
30 seconds.

The earbuds are reset to the factory default settings.

Alternatively, you can also reset the earbuds to the factory default 
settings using the Smart Control app.

What should I check if I can’t hear anything when using the ear-
buds?

Answer: 

Make sure that the earbuds are charged and connected to your Blue-
tooth device. The left earbud can only be used when the right earbud 
is also used as the right earbud controls the Bluetooth transmission. 
Please do keep in mind that the signal transmission range between 
the left earbud and the right earbud is approximately 30 cm. Addi-
tionally, make sure the earbuds are inserted into your ears correctly. 
Increase the volume on your Bluetooth device and on the earbuds by 
pressing on the right earbud’s touch pad until you hear the voice 
prompt “Volume max”.

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. Perform a reset of the earbuds.
