Left earbud not working properly only when connected to Z Flip phone

[userUtpT3nbdk0]

Hello. Bought Z flip, connected to my samsung earbuds, problem is, there'a no audio coming out of left earbud. Everything except audio works fine, calls, system sound, etc...but not audio, like music or youtube etc.... 

Connected these same earbuds to samsung s8 note, and it works fine. Tried to reset eaebuds from samsung gear, tried to reconnect bluetooth, but nothing seems to work.

Check for wax build up
often people with filthy :ear: ears fill the buds ports with wax and crud.
