I don't hear every background sound on my right earbud unless I open my case.

[userfyj69mhWXR]

On a few tracks(like Dj Khaled - For free... 15 seconds in the track), I dont hear certain instruments in the background when I have only my right galaxy bud connected. If I open my buds plus case, my left bud connects and now I can hear everything on my right earbud. But when I close the case, now the instruments quiet down significantly.

Can this be fixed?

Have you tried leaving the room while the right bud is connected to see if you still experience these symptoms?

Have you tried changing the equalizer settings in the Galaxy wearables app?

What type of device are you Galaxy buds paired with?

I would also recommend trying to reset your Galaxy buds. Give this link a try: https://www.samsung.com/us/support/answer/ANS00078085/
