Happened to me too and fixed it. Make sure the volume on the phine is all the way up. Then, change the settings on the buds to volume up control when you touch the right one. It'll bring up the volume to normal.
I am having the same problem too.
I had this issue with the old Iconx that I exchanged them twice until I threw them out. then thought maybe they figured things with Galaxy Buds, but the same problem happened and always the right one.
I did the troubleshooting Galaxy Note 10 + there is no Volume limiter in the setting and that's the only left thing in the troubleshooting I did not do.
Samsung if it's happening frequently to many users then it's not setting issue its firmware get it together and send us a fix and stop giving us useless troubleshooting steps.
thanks, loyal and angry customer.
this Fixed the problem for me... what i did was... remove the silicone plug and then took a
plier and pressed very gently over the silver grill part until i could see a little space removed it and then on the backside of that little grill was some black stuff i removed that and now it sound good again.
