#2 Why is there no audio output on one earpiece?
We fixed this behaviour in the latest software version.
Please update the TAT8505 device with the OTA FW
upgrade (v2.1.4.8). To recover an affected unit from this
issue, it is necessary to execute the pairing procedure to
ensure that both earbuds are linked together correctly.
How to execute pairing correctly:
1. Open the charging case.
2. Place both earbuds into the charging case.
3. Press and hold the function button on the backside of
the charging case for a few seconds.
4. The blue LED indicator will light up continuously
5. Wait until the blue LED indicator is off - this indicates
that the pairing procedure has been successfully
completed
6. If this still doesn’t work, double-click the function button
on the back of the charging case to trigger the factory
reset. This will be indicated by all three LED indicators
being lit up
