NOTE: See the second post in the comments section for my updates to this review.

I don't use the word "revolutionary" casually. Truth is, a product rarely qualifies for that accolade. But knowing as much as I do about noise-cancelling technology, I would not have believed that what Bose has accomplished with the QC20 series was even possible. In fact, I'd say they've created the best all-around earphone or headphone on the market today for everyday use with portable music players. Note that I said "best all-around" which is not to say it's "best" in every category. If audiophile sound quality is your top priority, then look elsewhere, as both my Etymotic 4PT and Shure 530 series earphones sound better than the QC20s. However, those better-sounding 'phones have other drawbacks in actual use (more on that later), and they now sit in a drawer while the QC20s go with me everywhere. Bottom line: if you're looking for the best noise-cancelling on the market today, bar none, combined with very good sound, the ultimate in comfort and convenience, all in a very small, lightweight package, the QC20 is for you. This review will focus on a comparison of the QC20 with the QC15, as well as with the Etymotic 4PT and the Shure ES530, all of which I currently own and have used for some time. And please be sure to check out the "Design Flaw" section at the end of this review before deciding if the QC20 is for you.

Noise-cancelling: The QC20 is signifcantly better than my QC15. Look, I've used Bose QC headphones for years, but the QC20 actually made me gasp the first time I turned on its noise-cancelling circuit.

These headphones are pricey, so you expect them to be amazing. And they are. The effect of cancelling out the drone of an airplane engine or central air unit is, to me, well worth the price.

As for sound quality, there are two caveats. I'm not an audiophile in the strict sense, but the reproduction of the highs and lows is superb while the mids may be just the tiniest bit overshadowed. I love the sound... when they noise cancellation is ON, or when it is in AWARE mode (more on that later). However, when the noise cancellation is OFF, or the unit is unpowered, the lows tend to be muddy and exaggerated. Quality definitely suffers when they noise cancellation is turned off. They're still fairly good, just not the crisp sound you get when they're on.

The other caveat is that, when noise cancellation is on, there is an audible hiss. That's the white noise that blocks out the ambient sound of the world. You'll love going from a noisy plane or train to just this quiet hiss, but sometimes the hiss the actually louder than my environment. In that case, I'd choose to turn noise cancellation off but that leaves the muddy, overpowered lows. So that's the dilemma: when it's quiet you have to choose between a white hiss and muddy lows. When it's loud, these are amazing headphones. When it's quiet... they're just really good.

As for "Aware" mode, it's kind of odd. I found that the full noise cancellation was actually more capable at drowning out voices than I was expecting (namely my two-year-old daughter whose voice is fairly sing-song and high-pitched). Aware mode allowed me to hear her, but her voice was mechanical and artificial sounding.

Taking the Bose MIE2i, the most comfortable and best sounding earbuds for extended use (8+ hours daily in my experience), and adapting noise cancellation to them has left me so impressed with the QC20i earbuds that the high price tag actually seems pretty fair IF having noise cancellation built into an earbud is an absolute necessity for you. However, there are some drawbacks to the QC20i earbuds, which, after several months of ownership, have left me reaching for my MIE2i earbuds more often than the QC20i set, with the rare exception being when the environment absolutely REQUIRES noise cancellation (skip to the end and read my 09/06/2013 edit for a summary of the QC20i vs MIE2i earbuds, or skip ahead to paragraph 7 for details regarding sound isolation and comfort of the newly redesigned tips on the QC20 earbuds).

I do have some insight in regard to the characteristics of the QC20i earbuds that hasn't been mentioned in other reviews yet, but first I'll touch on what everybody keeps bringing up. When comparing the sound output with the battery (i.e., noise cancelling) on and off, there is initially a difference in the color/tone that your ears will pick up. In short, these QC20i earbuds sound brighter (more high-end frequencies) with noise cancelling enabled and perhaps less bright, or for lack of a better term, "muddier" (more low/mid frequencies) with noise cancelling completely disabled (not talking about AWARE mode here at all). HOWEVER, it should be noted that your ears adapt extraordinarily fast to noise cancelling being enabled/disabled, and the intricate nuances of any genre of music are highlighted by the outstanding technology built into these Bose earbuds.
