Bose QuietComfort 15 Acoustic Noise Cancelling Headphones (2009)

The Quietest, Best-performing Bose Headphones Ever

The new QuietComfort 15 headphones, introduced today, are the result of more than 30 years of continuous Bose research in noise reduction technology — research that pioneered the category and has since led to breakthroughs for military applications, pilots and consumers.

Through significant engineering advancements in active and passive noise reduction technologies, the QC 15 headphones offer more attenuation in louder environments and across a wider range of frequencies — without compromising the audio quality and comfortable fit of the acclaimed QuietComfort headphone line.

“We believe the QuietComfort 15 headphones offer a combination of benefits unmatched in the industry,” said Sean Garrett, general manager of the Bose Noise Reduction Technology Group. “We’ve applied our research in noise reduction using an integrated systems approach — an approach as proprietary as our technologies. It requires meticulous engineering to ensure all elements of the headphone work together to achieve our very ambitious performance requirements.”

New Noise Reduction Technology: Only From Bose
The QuietComfort 15 headphones debut a more sophisticated, proprietary electronics approach to active noise reduction, placing microphones both inside and outside the earcup. This electronics system better senses the sound in almost any environment and then more effectively measures, compares and reacts to the noise — instant by instant — to produce an opposing cancellation signal.

New proprietary ear cushion technology provides additional passive attenuation. It features a new mechanical design and uses materials selected for specific acoustic properties to block more noise from entering the earcup.

Through research in user testing, the QC15 headphones overcome the inherent challenge of all headphones — the performance variation from user to user, caused by the difference in head shape and size. Bose engineers used a proprietary acoustic design to deliver a consistent experience for all owners.

The resulting performance is demonstrable. The engine roar fades further away, there is less distraction at work or at home, and when music is preferred, it is heard more clearly: within a quieter environment, more definition and detail are revealed.

The QC15 headphones benefit from decades of research in on-head audio. Proprietary active equalization technology electronically tunes the frequency response of the headphones, ensuring the accurate reproduction of instruments and vocals. Bose TriPort acoustic headphone structure is incorporated, a technology featuring small ports in the earcups that dramatically increase the low-frequency output of the system. Deep low notes are delivered naturally, without a manufactured “boost” and without increasing headphone size or weight.

The QuietComfort 15 headphones feature an around-ear design that maintains the renowned comfort of its predecessors. A single earcup cable 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.

A single AAA battery powers the QC15 headphones for approximately 35 hours of use. The green on/off indicator light flashes when there is approximately five hours of battery life remaining. For compact storage, the earcups rotate to a flat resting position and fit easily into the provided newly designed carrying case.

The new QuietComfort 15 Acoustic Noise Cancelling headphones replace the QuietComfort 2 Acoustic Noise Cancelling headphones. They are available in silver, beginning August 20, 2009 from Bose for the same price as their predecessor: $299.95. The QuietComfort 3 Acoustic Noise Cancelling headphones (featuring an on-ear design) are available for $349.95. Bose QuietComfort headphones are sold at select authorized Bose dealers, Bose retail stores, or toll free at 1-800-444-BOSE (2673).
