Sony has some of the most comfortable headphones around. Not only are they comfortable, though, they also give you some of the best sounding audio of any other pair of headphones as well. The Sony MDR-XB950BT/B are a pair that we would definitely recommend, these are their "Extra Bass" Bluetooth headphones and are pretty amazing. Amazon has them right now for just $99.99. Now these are certified refurbished, so they aren't brand new, but they are refurbished by Sony, so they are still in tip top shape. Sony also offers a 90-day warranty on the hardware here. It also includes all of the original accessories.
Bluetooth audio streaming is here with AAC and apt-X support, there is also electronic bass boost circuitry for added bass emphasis, always an important feature for bass heavy music. We're also looking at passive mode for normal, and cord operation without battery and a comfortable around-the-ear design here on the Sony Extra Bass Bluetooth headphones. Typically a brand new pair of these would run you around $198, and certified refurbished would be around $129. So getting them at $99 is definitely a pretty decent deal, and one that you shouldn't pass up if you've been looking for a decent pair of Bluetooth headphones.
