Audio-Technica's QuietPoint Noise-Canceling Headphones
Audio-Technica is known for its microphones, examples of which have brought you the clearest sounds from the Olympics, World Cup, Grammys, and Justin Timberlake and Metallica for starters. A company that good at reproducing should should know a thing or two about keeping sound out, which is the purpose of its QuietPoint active noise-canceling headphones.
As is the case in these kinds of units a miniature microphone in each ear cup detects environmental noise, and a corresponding sound-canceling signal is applied. They come in one over-the-ear and two on-ear flavors that range from 80% cancellation to 90% cancellation, and the two higher end versions fold flat into hard-shell carrying cases, while the entry-level model folds into its own travel pouch.
The rabbit in the hat, though, is that all of them have detachable wires – you can run them wirelessly on a triple-A battery. If your juice run out, you can plug the wire in so your music doesn't need to run out, too. Each model comes with an airline adapter, 1/4-inch or 1/8-inch adapters and an AAA battery, and they range from $99.99 to $219.99.
