Google introduced Google Pixel Buds 2 in April. As usual, some users suffer from audio problems that are likely related to faulty software. There is a lot of discussion on the Google support website, which indicates a specific problem with the Pixel Buds 2 that is triggered when the user moves.
Apparently the Pixel Buds 2 very often lose audio when users perform activities like a simple walk or jog. According to reports, in the list of users who suffer from this problem, we have many owners of Pixel 3 and Pixel 4 series phones. However, this problem does not seem to have to do with smartphones, but with the earphones.
Google is aware of the problem and is likely working on a software fix that will reach the earphones in the next few weeks. However, users affected by this issue are not very happy with the waiting time. Apparently there is a workaround that could potentially fix the audio problem. To activate it, users need to disconnect the headphones and reset their Pixel phones. Then you have to place and hold the button on the Pixel Buds 2 for about 15 seconds. If the light flashes white, the Buds 2 will be connected to the phone and the problem may be resolved.
This workaround seems to work fine with Google Pixel phones. However, you still have to check and test whether it works with your non-Google handset.
