If a headphone plays music on an airplane and nobody can hear it, does it make a sound? Though it’s not something we often think about, portable headphones have to do more than just put music in your ears — they also have to keep noise out. With the on-ear BT 330 NC ($199), Phiaton promises to actively remove 95 percent of ambient noise from the space between its drivers and your ears. While we think they have done a pretty good job in this respect, we wouldn’t recommend the BT 330NC as your only set of cans. BT 330 NC pairs 40mm drivers with active noise canceling, and the headphone uses Bluetooth 4.0.{/exp:char_limit}
