If you're commuting, you want a pair of headphones without a cord that's going to get tangled in your bag and in your clothes. If you're commuting, you also want a pair of headphones that blocks out the rattle of the train or bus and the chattering of the people next to you. It's usually a little hard to find a pair of headphones with both of these features packed into one, but Sony's new h.ear on Wireless NC combines both Bluetooth and active noise cancelling in an over-the-head, over-the-ear design finished in five different striking colours.
