About this deal

The sound reduction seems to be about the same as wearing a pair of good quality, correctly inserted, disposable foam ear plugs. My point is only that a perfect motorcycle earphone could possibly be made, but I wouldn’t hold my breath waiting for it. The button or buttons (for the 20i version) on the mic allows you to answer and hang up on a cell phone call if the headphones are attached to it.

Bose QuietComfort® Earbuds should be cleaned after every use by gently wiping the buds dry. Be careful not to allow any moisture to enter the earbuds through the ports. In addition, be certain not to force any dirt or debris into the ports. Do not blow air into or vacuum the ports or nozzle.High frequencies are much faster, with much less time to process and align the various peaks and valleys of these short-period, fast waves. There’s comfort in quiet. You can feel it the minute you put them on. The soft, plush cushions seal you in. You press the button and whoosh — the world fades, the music starts, and it’s love at first listen. That’s the power of our QuietComfort 45 Headphones with signature active noise cancelling technology and premium comfort. Bose QuietComfort 45 Headphones also deliver proprietary acoustic technology for deep, clear audio with adjustable EQ so you can tune your music to your liking. They're wireless headphones with a perfect balance of quiet, comfort, and sound you’ll enjoy all day long. Producing “unanswered” noise-cancelling waves in this manner would be unfavorable because it would be using battery power to just produce more distracting noise in your ear canal.

Editors' Note: This review is based on tests performed on the Bose QuietComfort 20i, the iOS-compatible version of the headphones. The QuietComfort 20i and the QuietComfort 20 are identical in price and design with one distinction: the QuietComfort 20i has a three-button iOS-compatible in-line remote, and the QuietComfort 20 has a one-button Android-compatible in-line remote. A better, more sound isolating interface between the earphone and the human ear canal would help a lot. I’m assuming that the Bose noise cancelling headphones of both the over-the-ear and in-ear type will be used mostly by airplane passengers. I see Bose headphones quite often on flights. The general idea is to get the sound out of your head so it feels less like you’re listening to headphones and more like you’re listening to an image served up by a traditional pair of stereo speakers.That could result in an earphone that protects the motorcyclist from more riding noise than the best foam plugs can. The microphone for cell phone calls is located on a small plastic “Control Module” assembly at the base of the “Y” formed by the wires coming down from the two headphones. Just by coincidence, the neighbor happened to be mowing his lawn on a riding garden tractor — a perfect test! The problem is volume — on bike, in-helmet noise can approach 120dB. Very, very few full size headphones are capable of this volume and we won’t even discuss earbuds (peruse a few specs sheets).

I think the QC20 really needs to have a detachable wire on the device connection side that’s maybe 40 cm long or so. Perhaps they are “tuned” to reduce certain sound frequencies but the noise inside a motorcycle helmet and an exhaust are beyond the scope of intended use. I’m not even sure most tiny earphone drivers can handle the power necessary to produce noise-cancelling sound waves of sufficient amplitude to effectively cancel the loud road noise motorcyclists are exposed to at highway speeds.

By the way, the Bose QuietComfort 20 Acoustic Noise Cancelling Headphones kit is available as either the QC 20 or the QC 20i.
