Wireless headphone interference investigation from muRata. Link here
Recently, the popularity of wireless headsets has been growing as the number of situations where people “play sports while listening to music” increases.
Bluetooth is frequently used for communication between smartphones and headsets. However, audio can skip due to communication errors, so countermeasures are required.
This is an extremely important point of user evaluation and a difficult issue to resolve.
Here we depict an actual case to explain the interference mechanism in the device which causes the audio to skip, and key points for improvement to introduce useful countermeasures for solving the problem.
We hope that you will use it as a guide to help your design work proceed more smoothly.
