Sound issues like no sound or interruptions with your Space One headphones can be due to connectivity, device compatibility, or low battery. This guide will help you troubleshoot and fix these common problems for a better listening experience.

1. Avoid playing games while on a call.

2. Some phones may have a high power output, which can cause voice distortion or excessive call noise when the headphone volume is too high. It is recommended to reduce the headphone volume appropriately.

3. If it is a software call, try to shorten the connection distance between the headphones and the device, confirm that the input and output selections of the device or call software are correct, switch the output on the call software to the device's built-in speaker and then switch back to the headphones to restore normal call quality.

4. Rule out the impact of poor network speed or excessive environmental interference. 

You can try switching to a different network connection, and changing the environment where the device and headphones are located to reduce the impact of highpower output interference sources.

5. Rule out the impact of outdated product firmware versions, call software, and device system versions. You can try upgrading the headphones, call software, and device system versions.
