Klipsch has released a stylish new pair of noise-cancelling headphones for those who prefer a little more signal and a lot less noise. The Klipsch Mode Noise Canceling Headphones wrap a pair of leatherbound speakers in a smooth black-and-copper shell. Each speaker includes a 40mm driver for deep bass and smooth mids, plus a 15mm tweeter for clear, crisp highs. The active noise cancelling system runs on a AA battery for up to 45 hours, then reverting to a standard set of stereo phones with classic Klipsch output. They’ll soon be on the market for $349, a price well-suited to the frequent first class traveler.
