The American branch of JVC has announced a new pair of high-end headphones, the HA-NC250s. A noise-cancelling set, the 250s continuously monitor cancellation for feedback, and are thus able to kill 85 percent of outside sound. To improve this further, the earpieces have padding and a doubled housing structure to create isolation. For extra comfort the padding is made of a memory foam that conforms itself to the wearer's shape.
Audio is produced by two 1.6-inch drivers, and the set can be used with or without noise cancelling switched on; a single AAA battery will power cancellation for approximately 50 hours. JVC plans to ship the 250s in early August at a cost of $200.
