Bose quietcomfort 3 are Acoustic noise cancelling headphones manufactured by Bose, Inc of Framington, Massachusetts. The headphones retail for $349 and were released on July 13, 2006.

The headphones come accompanied with a rechargeable battery, wall charger and a carrying case with detachable strap.

Features and functions of the Bose quietcomfort 3 are:

1. Rechargeable battery
2. Wall charger
3. Carrying case with an optional strap
4. Two plug adapters
5. Two cable lengths
6. Noise reducing technology

Putting £275 of your cash into headphones may seem like an extravagance but the pouch and its contents show you that you are getting everything that makes international travel more comfortable. Apart from the QC3's themselves, there is a jack adaptor which will convert to all varieties of aircraft entertainment systems and the battery charger, all built well and with a sense of quality.

Arriving at the salubrious London Stansted we felt much more refreshed than on previous flights, we can't entirely attribute this to the QC3's (as opposed the 60" seat pitch!) but they did help us get some good hours sleep and made the journey more relaxed. As to if they are worth £275 we'd say a cautious yes, just make sure you are going to be exercising your carbon footprint a few times a year or at least a few Tube journeys a week. http://www.lordpercy.com/bose_quiet_comfort_3_review.htm - Review by the Lord Percy Website

In the end, if you're trying to decide between these headphones and the QuietComfort 2s, we can only say the choice isn't easy. The smaller form factor and rechargeable battery are definite pluses in favor of the Bose QuietComfort 3s, but the more refined sound and the over-the-ear design of the QuietComfort 2s have their appeal. If money is no object, you can't go wrong with either model, but ideally, we'd like to see the company drop the price on the QuietComfort 3s and QuietComfort 2s to $299 and $249, respectively. We think $350 is a lot to pay for headphones, even those with a rechargeable battery.http://reviews.cnet.com/headphones/bose-quietcomfort-3/4505-7877_7-31929466-2.html?tag=txt;page - Review by CNet

Frankly, the only reason to prefer a pair of noise canceling headphones to other alternatives is its ability to filter out various sorts of outside noises, so in the absence of strong performance of this feature, it’s hard for us to recommend the QuietComfort 3s to most iLounge readers. Though they sound good - again, not great - when you’re in quiet environments, they’re not standouts in noisier ones, and you can do substantially better on both sound quality and passive isolation for the $350 asking price. Even though you’ll need to compromise an inch or two on size and an ounce or two on weight, we’d sooner recommend the cheaper QC2s instead, or the much cheaper Logitech Noise Canceling Headphones if you’re willing to accept fewer frills and some compromises on sound quality. At this price, if you’re willing to consider in-canal alternatives, you should also consider some of the stronger passive isolating earbuds from companies such as Etymotic (ER-4P) and Ultimate Ears (super.fi 5 Pro), which deliver similar ambient noise reduction and superior audio quality through tiny, earplug-like designs.http://www.ilounge.com/index.php/reviews/entry/bose-quietcomfort-3-qc3-acoustic-noise-cancelling-headphones/ - Review from ilounge.com
