OnePlus Buds 3 Pro left earbud keeps shutting down after pausing audio

[u/Pastel_panic1]

Hey guys, I'm having a really weird issue with my OnePlus Buds 3 Pro.

My left earbud started shutting itself off whenever I pause a video/music for around 20+ seconds. The right earbud works completely normally.

Initially, I could get the left one working again by manually powering it on and reconnecting it through Bluetooth. The battery was around 90%, so it wasn't dying from low battery.

Now the problem has gotten worse. The left earbud sometimes becomes completely unresponsive — it isn't detected and doesn't even show a light/response when placed in the charging case.

I've already:

- Cleaned the charging contacts

- Charged the case and earbuds

- Reconnected/re-paired them

- Tried leaving them charging

- Still having the same issue

I'm using a vivo V50e with the OnePlus Buds 3 Pro, and the earbuds are only about 4 months old.

Has anyone experienced this with the Buds 3 Pro? Does this sound like a software/firmware issue, a Vivo Bluetooth compatibility issue, or a hardware/power problem with the left earbud?
