Features

Overview: The Harman Kardon NC over-ear noise-canceling headphones let you enjoy music from your smartphone, home stereo, or other devices, in peace and quiet. The NCs are made of high-quality materials to provide an exceptional acoustic performance. The headphones have 40mm drivers and a unique baffle design for clear highs and extended bass response. The NCs have interchangeable parts that let you custom fit the headphones to your head. The ear cups swivel to lay flat for easy storage in the supplied leather case.

Noise Canceling Technology: The H/K NC headphones feature Harman's closed-loop, active digital noise-canceling technology, the same technology that was developed for acoustic installations in luxury cars. The noise-canceling circuit operates on a built-in rechargeable battery that lasts up to 40 hours. The battery charges in about 2 hours via the supplied USB cable. (Charging from a laptop computer may take longer.) When the battery is exhausted, you can continue to listen to your music by switching off the noise canceling feature, bypassing the circuit.

Audio Cable with In-line Remote/Microphone: The supplied 58" audio cable plugs into the left ear cup via a 2.5mm sub-miniplug, and is terminated with a durable straight 3.5mm plug. The cable has an in-line 3-button remote control and microphone, approximately 6" from the connection to the left ear cup. This places the microphone in close proximity to your mouth so your voice can be heard clearly during phone conversations. The controls allow you to raise and lower the volume with the outer buttons, while the center button can control your phone calls or music. The remote control is "Made for iPod, iPhone, and iPad", which means that it is certified to meet Apple performance standards. During music playback and phone calls, the control function is determined by the number of center button presses:

• One Press: Pause/Play; Answer/Hang Up
• Two Presses: Skip to next track
• Three Presses: Skip to previous track
• Press and Hold: "Voice Over" feature (such as the iPhone's Siri), if available

Design: The headphones have a closed back design and slow-retention premium foam ear pads to keep outside noise out and keep your music and phone conversations from leaking out. The ear cups swivel in two directions to maintain the acoustic seal around your ear.

Interchangeable Bows: The H/K NC headphones come assembled on a "small" metal headband bow. If you need or desire a larger fit, you can remove the ear cups and padded from the original bow and attach them onto the supplied "large" spare metal bow.
