Innovative Noise Cancelling Headphones — The PSB M4U2

The first thing you're bound to notice while holding the PSB M4 U2 headphones is the fact that they are not that big for a full-size, over-ear design. It comes in a handsome, zippered semi-hard case, which carries two 59-inch detachable headphone cords: one cord comes with an in-line remote/microphone and monitor control, the other with just a monitor control. There's also an extra set of ear pads, a 1/4-inch adapter, a cleaning cloth, and an airline adapter.

The substantially sized earphones conveniently fold up when packed in the case. You can plug the cable into either earcup, so when travelling you can place the cord in the best place for staying out of the way.

The bass is simply awesome making it great for listening to music. Active noise cancelling works very well in almost all conditions, with no room for complaints. Treble is a little weak, but sound is clear throughout the high notes. It is also very
good at high and low volumes, with no scratching of sound or any sign of over-bearing on your ears. PSB Speakers' M4U 2 Active Noise Cancelling Headphones may still be one of the most expensive pairs of noise-cancelling headphones on the market, but they're also one of the few that can still play after
the batteries are close to drained. If you're an audiophile in the market for noise-cancelling headphones that don't sacrifice on sound quality, the M4U 2s is the pair to buy.
