Sennheiser MM 550-X Wireless Headphones

No one has ever called this venerable German headphone maker a fashion leader, but when it comes to acoustic engineering, Sennheiser is among the elite. Its new MM 550-X wireless model ($500), in the company’s Travel Series line, may be the perfect headphones for airplane travel. Wireless Bluetooth technology takes care of the cords that tangle up in your fork during dinner, and the active noise suppression reduces airplane-engine din. A Talk Through feature lets you easily communicate with the flight attendant for a refill without having to take off the headphones, and a wide frequency response of between 15 and 22,000 hertz makes for superb sound quality.
