**Q: If you only use one earbud dows the other one work if u have the main one on**
A: Thanks for your question. CX 400BT True Wireless earphones deliver stereo audio via their left and right earbuds. However, the user can use the right earbud, which serves as the ‘master’ earbud to establish the connection to the paired Bluetooth device, as a stand-alone unit for phone calls and voice assistant access.
