If you love the idea of monstrous bass response, but find that the Synchros S400BT is a bit out of your price range, the SOL Republic Tracks Air is a slightly-less expensive option, while the Outdoor Technology DJ Slims is a solid, inexpensive Bluetooth pair.

One of the most influential letters of the alphabet and sound JBL are at it again. As one of the pure quality sounds in headphones, speakers, etc in the game, JBL blesses you with a beautiful option of listening to your favorite music via Bluetooth.
