I recently bought Sony MDRXB650BT/B Extra Bass Bluetooth Headphones and overall they are great. However, the main reason I bought them was for work calls, but when I pair them with my MacBook Pro Retina (Early 2013), the sound only plays out of one ear or is extremely low quality (but out of both ears). The sound is perfect when I connect to any other device (iPhone, TV, etc) - so there is no damage to the product. Sometimes it'll switch back and forth between one ear or low quality out of both while paired with my MacBook. It's extremely annoying and frustrating, and I can't find a fix or explanation. I've tried several "solutions" to no avail. Any help would be very much appreciated!
