I often just use one of the in-ears of my Jabra 75T. Recently I figured out that when I use both in-ears headphones, the right one was significantly louder than the left one. After a quick hearing test, I was convinced that it is not a problem with my hearing but with one of the headphones.
After some back and forth, the easiest solution was:
Simply hard reset the headphones in 2 simple steps.
- take the headphones out of the case and ensure they are turned on (green LED)
- Press and hold the buttons on the headphones for ~10s until the right one flashes blue and then both LEDs flash purple
- reconnect to your phone
