Hey, I just bought these ear buds and wanted to test them with my phone, which is the OnePlus 3t.
Bluetooth is fully backwards compatible so it should even work with my phone which has bluetooth 4.3.

So no sound is playing, tested with Spotify and Youtube. Also for some reason the playback on Youtube is really laggy (doesnt matter on which resolution of the video) when the ear buds are connected.

I already updated the firmware through the EarFun Audio app and reset the Air Pro 3 properly like it's suggested here in the forums (deleted them as a bluetooth device, pressed the botton on the case until they blink with purple colors etc.).

Which did not help at all, still no sound and laggy Youtube playback.

They work without any issues on my Windows 10 PC with a Bluetooth 5.0 stick.

Would be nice if someone could help me with this since the ear buds sound great on my PC.
