Ratings and reviews

It doesn't work. It can see the earphones, I try to update, it is showing "0%" for a few seconds and then says "we lost connection to your headphones". However, the connection is not lost. I even tried listening to music at the same time.

ALERT! Could be destructive. Had 0.0.1187.0 version on my Tune125BT, updated to 0.0.1188.0 (although it required several dozens of tries, often with 0.0.0.0 version). SOUND SEEMS WORSENED: everything became hollow/booming, violins and flutes destroyed.

Doesn't work. App correctly detects battery level, but says current firmware is 0.0.0.0 (!), and that an update to 0.0.1183.0 is available - but it always fails. (Tune215BT)
