The Able Planet NC300 active noise-canceling headphones are the best I've ever used. Their noise-canceling feature can be activated on the side of headset and produces white noise to reduce undesirable sounds. They also have in-line volume control, which comes in handy when adjusting the volume. The sound quality is exceptional, thanks to the Linx Audio technology, which provides clear speech and full, rich sound for listening to music so quality isn't compromised even at low volumes.
Though the NC300 headphones are great, they aren't perfect. Because they're designed to fit snugly, they can become somewhat uncomfortable when worn for an extended period. Adjusting them will help, though. Although the ear cups mostly fit comfortably, when I wore certain shaped earrings, they felt awkward, but despite the discomfort, the sound and noise-canceling feature weren't affected.
Despite those two minor complaints, the headphones performed fantastically. Music or voice came through very clearly, and I could drown out distracting voices or sounds that would otherwise hinder my productivity.
If you need to focus on a project at the airport or in the office, these headphones are the perfect solution. They can be used with iPhones, iPods and MP3 players, and according to the maker, are ideal for hearing aids, and audio and communication devices. The headphones come in a black carrying case.
They say good things come in small packages, and this certainly is true for the NC300.
