Can I change the touch control assignments?

Answer: 

Operation is brilliantly intuitive thanks to customizable touch con-
trols that let the user define their preferred way of controlling audio, 
calls or activating the voice assistant like Google Assistant or Apple 
Siri. 

Left and right earbuds may have different control assignments and 
can be changed easily by the Sennheiser Smart Control app.

Although customization is made easy, the default touch control 
assignments have been created to be a great option for users that 
want to control music, phones calls and voice assistance. 

Can I use one single earbud as a stand-alone device?

Answer: 

CX True Wireless earphones deliver stereo audio via their left and 
right earbuds. It provides intuitive controls and is very easy to han-
dle. To make it even more convenient to use, we introduced a "Role 
Switching" feature.  In a nutshell, role switching is about possibility 
to use earbuds individually. It can be used in different situations - for 
example when you need to stay aware while still listening to the 
important call. You can dynamically decide whether you want to use 
both earbuds or only one. 

Here we have two cases - when listening to the music or consuming 
content and while being on the call. In the first case, when putting 
one of the earbuds back into the charging case you might experience 
a small interruption in music reproduction due to the fact that ear-
buds will change their "roles" - from the primary to the secondary or 
back. In the second case, you will not experience any interruptions 
and will be able to stay 100% focused on the call. 

How do I access the voice assistant?

Answer:

Users can activate a preferred voice assistant such as Google Assis-
tant or Siri by a convenient touch gesture on the earbud. The voice 
assistant selection depends on the specific smartphone configura-
tion. Via the Sennheiser Smart Control app, the user can customize 
this control to use another touch gesture for voice assistant selec-
tion or, if preferred can disable voice assistant access.

Are the CX True Wireless waterproof?

Answer:

CX True Wireless earbuds has a splash resistant design for all 
weather conditions. They have been successfully tested to meet 
IPX4* standards, which means they are splash resistant and can be 
used in the rain. However, they are not meant to be submerged under 
water, worn in the shower or rinsed under running water. Wetted ear-
buds should be dried up with cloth before docking back to charging 
case.

* Rating according to International Protection Marking standard IEC 60529. The earbuds were 
tested under controlled laboratory conditions. The earbuds are splash resistant for non-water 
sports and exercise. Splash resistance might decrease as a result of normal use. Do not charge 
wet earbuds. The charging case is not splash resistant.
