Right headphone a lot quieter than the left one
Hi everyone,
I've bought a new MacBook Pro (Retina, 13-inch, early 2015) four days ago and the first time I plugged in my headphones I had this problem - the left headphone is working fine and the right one is a lot quieter. At first I thought it wasn't working but then I turned the volume up to find out it is working (but quite bad). Yes, I did check the sound settings and the balance was centered. I also checked the Audio MIDI Setup and the channels were set on the same value. I've tried three different pairs of headphones so obviously the headphones are not the problem. Could somebody please help me?
Thanks.
MacBook Pro with Retina display, OS X Yosemite (10.10.2)
