Bose QuietComfort 15QuietComfort

The Bose QuietComfort 15 is an acoustic noise-cancelling headphone that comes from over 30 years of continuous Bose research in noise reduction technology. The QC®15 headphones is aimed to provide more attenuation in louder environments and across a wider range of frequencies without compromising the audio quality and comfortable fit for use. The QuietComfort 15 headphone places microphones both inside and outside the earcup. This electronics system senses the sound in the majority of environments, then measures, compares and reacts to the noise to produce an opposing cancellation signal. The unit also features proprietary ear cushion technology which provides additional passive attenuation and a mechanical design and materials selected for specific acoustic properties to block more noise from entering the earcup. The QC15 headphone is designed to overcome the inherent challenge of all headphones as well as the performance variation from user to user, caused by the difference in head shape and size. It features proprietary acoustic design to deliver a consistent experience for all owners, active equalization technology which electronically tunes the frequency response of the headphones, providing users with optimal reproduction of instruments and vocals. It also supports Bose TriPort® acoustic headphone structure, a technology featuring small ports in the earcups that increase the low-frequency output of the system. This allows the headphone to deliver deep low notes naturally, without a manufactured “boost” and without increasing headphone size or weight. Other features on the QuietComfort 15 headphones include an around-ear design that maintains comfort during usage, a single earcup cable which can be detached for untethered noise reduction (once the cable is removed, listeners need only flip a switch on the right earcup to activate the proprietary technology); single AAA battery which powers the QC15 headphones for approximately 35 hours of use (there is a green on/off indicator light which flashes when there is approximately five hours of battery life remaining); and earcups that rotates to a flat resting position that fits in storage in a provided designed carrying case. The QuietComfort 15 Acoustic Noise Cancelling headphones are available in silver, beginning August 20, 2009 at the price of $299.95.

Specifications
Dimensions
The Bose QuietComfort 15’s overall headphone dimensions are 7.5″H x 6.5″W ( 19 cm x 16.5 cm ) from the ear cushion outside dimensions to 3.75″H x 3″W ( 9.5 cm x 7.6 cm ). It weighs (with cables) 7.3 oz (207.5 g).

Headphones
The QuietComfort 15 area headphones that are designed with over-the-ear form factors and supports connectivity wirelessly. Its sound output is stereo, and the unit features Noise cancelling circuit, Foam ear cushions and Active equalization.

Miscellaneous
The headphone comes with a cable, carrying case, AAA battery and an Airline adapter. The unit features proprietary Bose innovations that use microphones both inside and outside each earcup to sense and reduce more of the sounds around the listener and is redesigned with ear cushions that use new materials to establish acoustical seal that helps further reduce noise while providing a comfortable fit. It also supports Bose’s TriPort® acoustic headphone structure, that features tiny vents in the earcups to enable a tonally-balanced audio performance—including reproduction of deep, low notes—from relatively small and lightweight headphones. Other features include Active EQ which electronically fine-tunes the headphones’ frequency response to deliver optimal sound; single, detachable audio cable and fold-flat earcups that rotate 90 degrees for storage and portability in the included case.

Power
It is powered by one AAA type battery that provides up to 35 hours of usage time.

Reviews:

“While they’re no bargain, the Bose QuietComfort 15s currently offer the best sound and silencing capabilities in a pair of noise-canceling headphones.” – (CNET, 2009)

“Bose takes noise cancellation to the next level with the QuietComfort 15 headphones, and while the audio performance isn’t perfect, it’s an improvement over previous iterations.” – (PC Mag, 2009)
