Only left Powerbeats Pro doesn't work on my MacBook, but everywhere else works fine

Basically today my right Powerbeat Pro decided to work with my MacBook. My left one only does the connected little sound when paired with my computer and that's it, doesn't reproduce audio.

Already reseted my MacBook, and my Powerbeats. The weird issue is that they are both well charged, and both work fine on my iPhone. I can control the volume from my left one and pause the music if i use the buttons, so it basically works but doesn't reproduce the audio from my computer.

Also forgot to say that when my right Powerbeat is in the cage and I'm using my left one the audio works fine, but when i put the other one in my ear it switches automatically to that one. And in case of putting both at the same time, it chooses the right one over the left one.
