Acoustic Noise Canceling Headphone
Technology: Through a combination of proprietary electro-acoustic and
ergonomic technologies, the QuietComfort 2 headphones provide full-spectrum
noise reduction, dramatically reducing unwanted noise while remaining
lightweight and easy to wear, even during long airplane flights. The
QuietComfort 2 headset works as an integrated system. The ergonomically designed
earcups feature soft, supple ear cushions that gently snuggle your ear. In
addition, revolutionary TriPort headset technology reduces the size, weight and
clamping force of the earcups. When combined with advanced electronic circuitry,
this proprietary technology results in superb noise reduction performance over
the full spectrum of human hearing.
Active Equalization: The Quiet
Comfort 2's active equalization electronically tunes the frequency response to
provide superb audio performance.
Detachable Cord: If you plan to
use the Quiet Comfort 2 headphones for noise reduction only, you can simply put
the headset on and switch on the noise reduction circuitry. There is no need to
connect the audio cord. When you're ready to listen to audio, just plug the cord
into the left earcup and into your audio source. The headphones use a single
earcup audio cable, which gives you far fewer problems with tangling than
Audio Attenuator: On one end of
the audio cord, the Audio Attenuator has a High/Low switch to adjust the output
volume of different audio sources. The Low setting is typically used for airline
audio or audio devices that use AC power. The High setting is typically used for
battery-powered audio devices.
Headband: The headband is
padded for comfort, especially for long-time use. You can gain up to 3 inches in
headband length, allowing comfortable settings for a wide variety of head sizes.
Supplied Accessories: The
headphones come with a 62" headphone extension cord, a 1/8" to
1/4" headphone plug adapter, and an airline stereo audio dual-plug adapter.
Battery: The Quiet Comfort 2
headphones are powered by a single "AAA" battery (supplied), which
loads into the right earcup. The supplied battery should provide approximately
35 hours of use. The low-battery indicator lets you know when you're within 5
hours of battery life remaining. Rechargeable Nickel-Metal Hydride (Ni-MH)
batteries can be used, however, the low-battery indicator may not provide an
accurate indication of the remaining battery life.
Carry Case: You can store the
headphones and accessories in the supplied carry case. The earcups rotate so
they can be stored flat in the crushproof case. The length of the supplied strap can be
adjusted for ease of use. Inside the case, there's a handy zippered
pouch for storing the cords and accessory plugs, and a 3" x 4-1/2" ID
card or business card holder with a see-through window. Both the zippered pouch
and business card holder have Velcro on the back and are removable.
Courtesy Cards: The
manufacturer has provided 10 courtesy cards to pass along to persons inquiring
about the Quiet Comfort 2 headphones. The cards contain information about the
headphones, including how to purchase a pair.
