How do I check for, receive and install firmware updates? 

Answer: 

When using the Sennheiser Smart Control app, you will receive a notification once a new 
firmware release is available. The app will guide you through the update process. The firmware 
update will be installed over-the-air via the Bluetooth wireless connection.  

Additionally, you can check for the current firmware release status in the Smart Control app’s 
settings.  

  

How can I control the sidetone during calls? 

Answer: 

For comfortable calls the MOMENTUM True Wireless 2 has an integrated sidetone feature. 
"Sidetone" is the term given to the sound that is generated when a user hears their own voice in 
their own ear piece. The sidetone feature enables a natural experience of hearing one’s own voice 
when speaking during a call (own voice reception).  

You can enable or disable the sidetone in the Smart Control app’s device settings.  

  

Do the earbuds switch off automatically when not in use? 

Answer: 

The MOMENTUM True Wireless 2 has integrated power-saving features. When the earbuds are 
disconnected from a Bluetooth source and not in use, they will switch off automatically after 15 
minutes.  

To turn the earphones on again, press each touch pad for more than 2 seconds. 

  

How can I activate aptX on my Mac to receive the highest possible audio quality?

codec is active, connect your MOMENTUM True Wireless 2 to your Mac and start music 
playback. Press and hold the option key and click the Bluetooth menu bar icon and navigate to
