As a frequent flier, I depend heavily on noise cancelling headphones to get me through long flights, and I purchased these Bose headphones to replace an older Sennheiser in-ear set. I knew what I was getting, more or less, because I had purchased a pair of QC15s for my husband a few years ago, and I had used those. With my own headphones on a couple of transatlantic flights, however, I fell in love with these. The active noise cancellation cuts out what seems like 95% of engine whine -- the sound inside the airplane seems deafening when I take them off. That said, there's a decided difference between choosing an over-ear set and an in-ear one -- and, as much as I love these, I'm not sure I made the right choice. Scroll down for more on that topic.
If you've never used active noise cancelling headphones, then it helps to understand what you're getting. Active noise cancelling technology uses an electronic hiss, powered by a battery, to cancel out a specific noise frequency, one that is created by engine whine or other mechanical sounds. These are not soundproof headphones or ear protection. You can hear the voices around you, albeit muffled. For instance, when the pilot comes on over the PA system, I can hear it and might even be able to hear exactly what's being said, even if I'm listening to music or a movie. (I don't use a high volume, though.) The kicker, though, is how much engine whine is filtered out. Most people aren't aware of just how loud the inside of a plane cabin is -- and you won't, probably, unless you use noise-cancelling headphones. Bose is unparalleled in noise cancellation technology -- my Sennheisers were good, but not this effective -- and, as a result, I turned these on without sound for a couple of hours just to protect my ears.
Although the audio quality is very good, I prefer other headphones while on the ground, mostly because these aren't as precise as some others that I own. They do reproduce a full range, from bass to treble, though, so if you can only afford one set and need noise cancellation features as well as excellent sound, then don't hesitate with the Bose. You won't find another headphone with this quality of noise cancellation, period, so you'll end up disappointed by compromising. Flicking the noise cancellation on improves the sound, even without engine whine, by giving it more depth, although, again, the sound is fine even in regular mode. Still, at the price, I wouldn't recommend these unless you need the noise cancellation.
The build quality is good, with comfortable padding around the ears. The ear cups float on articulated joints to adjust to a variety of head shapes. That said, these headphones pose certain problems for women in particular. I cannot wear earrings, even studs, without some discomfort, and the articulated part over the ear cups sometimes catches my hair and pulls out a few strands. Those of us with smaller heads don't get the same contact of the headphones against the head. My husband tried on mine, and the cups made full contact around his ears while I had a slight, almost impercepible gap. The headpiece is adjustable for larger heads. I have to use mine on the smallest setting. The inside of the ear cups is blue with huge R and L on the fabric. It looks tacky but it's extremely useful, and I see it only when I first take them out of the case.
For those who are contemplating whether to get over-the-head or in-ear headphones: in-ear models tend to block out more ambient sound. They plug your ears in ways an over-ear one will not. Bose makes an in-ear noise cancelling set (QC20) that I was considering before I bought these, and I now wonder if they would have been better for me since in-ear doesn't bug me the way that it does other people. My Ultimate Ears in-ear set blocks out sound better, although not engine noise. I went for the known quantity, however, since I had tried my husband's. As I said earlier, I'm not sure I made the right choice even though I'm extremely happy with the performance of the QC25.
The case for the QuietComfort 25 is more compact that the one for the QC15, and so takes up less room in my bag, something I was initially worried about since space is always at a premium. It comes with one AAA battery, an airplane adapter, and the detachable cable with in-line mic and music controls.

Comfort, Sound Quality, Noise Cancelation, Noise Leakage, Craftsmanship/Durability, Battery Life, Case, Style, Features, Price
I'll start by stating that I am replacing an older pair of active noise canceling headphones that I used for 5-6 hours/day for the past four years in varying office environments. The old pair had a plastic swivel attaching the ear cup to the head band which finally broke after about a thousand times (literally, do the math) placing them into and taking them out of the case.As I mentioned I use these headphones primarily in an office environment to listen to music (I'm a software developer) and/or to just block out the constant hum of HVAC systems, etc. I've been reading countless of reviews on numerous headphones looking for something that fits my needs and after much consideration I settled on the QC25's.The main things I took into consideration when looking for my replacement headphones were: comfort, sound quality, noise cancelation, noise leakage, craftsmanship/durability, battery life, case, style, features (wireless/playback control/etc), and price. Here's how the QC25 rates:Comfort - 5/5 - These are the most comfortable non-studio headphones I have ever worn. They are fairly light weight and have a large over-ear design. The ear cups are also fairly deep so there's no contact between my ears and the ear pieces at all. The cups rotate to allow you to wear these comfortably on your head however you desire. The material on the ear cups is a soft foam filled leather that doesn't apply too much pressure to the side of the head (I wear glasses so ear comfort is of utmost importance to me). There is also a foam filled suede material on the top of the headband making the headphones rest comfortably on your head.Sound Quality - 5/5 - Excellent and well balanced. If you're looking for headphones that just amplify the lows and the highs, these are not for you. If you want solid lows, crisp highs and a pronounced mid-range then look no further. These headphones play the music as-is and let you control any equalization you feel is necessary for your best listening experience. I suppose if you're just into thumping base and are listening from a mobile device that doesn't support custom equalization you may be better off with a different brand.Noise Cancelation - 5/5 - The first thing I did when I got these is pop in the included battery and walk into my furnace room (the furnace was running) to see the impact and it was profound. These far outperformed my previous noise canceling headphones (which weren't too shabby). At work I sit near a call center where there are typically 4-6 people on the phone during busier times. There are also heat pump units in the ceiling which hum and buzz throughout the day (especially since the temperatures have been in the single digits the past several weeks). The second I flip the switch on all of the humming and buzzing is gone without a trace. The call center noise is also greatly reduced (I'd say about 70% quieter than without the headphones on) to the point that I have a hard time focusing on any one conversation. This is of course remedied when I turn on some music and the awesome sound quality completely drowns out any remaining distractions. I frequently have colleagues walk up and do jumping jacks to get my attention as I don't even hear them knocking on my desk when I'm "in the zone".Noise Leakage - 4/5 - One of my slight disappointments with the QC25 is the level of noise leakage (the amount of sound that can be heard by people nearby). At a comfortable listening level the noise leakage can be heard from 4-5 feet away. If you like to listen to your music loud, expect people up to 10 feet away (in quiet environments) to sing along with your tunes. I'm currently in a cubicle environment so the closest person to me is about 5 feet away, however at my previous office I sat 3 feet from another guy with no divider so it definitely would have been an issue there (except he wore headphones all day as well ;).Craftsmanship/Durability - 5/5 - I only have a couple pairs of headphones to compare these to but they look like they are made well. The joints and swivels are made with metal parts and are fastened with screws. The headband is made from a metal ribbon surrounded by plastic. The cup internals are covered with a rugged cloth (as opposed to the foam covering which often disintegrates after extended use). The ear cups are a foam filled leather material that seems durable (same style on my old headphones and those lasted 4+ years). Even the cord is made with sturdy gold-plated ends. They flex well and seem like they would last a long time even on larger heads. (I had a friend who ate through headphones due to his large head).Battery Life - 4/5 - So far the battery life on these is acceptable. The noise canceling feature is typically on for 6-8 hours a day and I find that so far I've gone 2-3 days before swapping batteries. I am also using some older rechargeable batteries which probably don't have the same life that they once did. I have not completely drained a standard AAA battery to see how much life you get out of those. The battery life is comparable to my old headphones (which is where the batteries came from) and is sufficient for my needs.Case - 4/5 - The carrying case included with the headphones is sturdy and has a nice look/feel to it. The headphones fold up rather small and fit neatly into the case leaving just enough room for the included headphone cable and maybe an adapter or two. There is an elastic pouch on the back side of the case but it is designed more for storing your instruction manual or thin items (perhaps an extra cable?). Because of my obsessive use of the headphones I own a small USB powered AAA batter charger which fit perfectly into my old case...when my batteries were low I could pull out the charger and charge a battery while my backup was in the headphones...not so with this new case. Fortunately I almost always use the headphones with my macbook pro so I can keep the battery charger in my laptop bag when I need it. Aside from that, the case is very compact and does include a little slot for a spare battery (one AAA is included) as well as an airplane adapter.Style - 5/5 - I own the black design and I like them. I'm not a style buff when it comes to headphones but I certainly don't want some big ugly things on my head. These are sleek with an undertone of teal on the cups and on the in-line playback controller. The plastic is a brushed style and I am overall very pleased with how these look.Features - 4/5 - The only feature I was passively looking for in headphones that these don't have is wireless capabilities. This isn't a show stopper for me, of course, since I came from wired headphones and I am typically always at my desk when using them. Again, I do not use these while walking about listening to music from my phone or music player so I can't speak to that experience. There are inline playback controls which consists of a small (1.25" long) control with three buttons. There is a volume up button, a volume down button and a center button to control playback. A single press of the center button will play/pause your music, a double-tap of the button will skip to the next track and a triple-tap will skip to the previous track. I already have keyboard controls for this functionality but I imagine if listening to a music device (that supports inline playback controls) this would be convenient.Price - 4/5 - Who doesn't want more for less? For the quality and package you get the price is fair. If you're looking for an exceptional pair of headphones with great noise canceling, great sound and decent features this is a great option to consider.Overall - 4.5/5 - I would recommend these to anyone that doesn't mind being wired to their audio source and who doesn't mind anyone within their reach being able to hear what they're listening to. I'm extremely satisfied with my purchase and would buy them again.

Design
While the incredibly comfortable QC 25 retains the overall look and feel of it predecessors, there are design updates that seem to acknowledge that a simple black-and-metallic design no longer cuts it in the current headphone market. There's now a white-and-tan color option in addition to the more standard black-and-gray model. If that's not enough for you, you can customize your headphones for a little extra and give them a variety of wild color combinations. It's a decidedly un-Bose move, and speaks to the influence Beats has had on headphone design.Bose QuietComfort 25 inline
The headband is covered by canvas-like cloth on the top, with ample padding on the underside. The circumaural (over-ear) earcups are, as always, exceedingly plush. Aqua blue grilles line the insides of the earcups, with large L and R letters identifying each cup's respective ear.
A detachable cable connects to the left earcup, and the Power switch (which light ups green and activates the noise cancellation circuitry) is located on the right ear. Bose has made a significant design improvement in the QC 25 and given it an ability previous QuietComfort models lacked: It can be used as passive headphones without power. In other words, you can still listen to audio when the battery is dead, or simply when you don't really need the noise cancellation feature running. There's no auto-off function, so it's pretty easy to mistakenly leave the Power on and kill your battery quickly, leaving you with no noise cancellation feature (but at least with a pair of still-functional headphones).
The included cable features an inline remote control and microphone. Many headphone pairs these days ship with a second replacement cable, and it would have been a nice inclusion with the QC 25 for this price.
Bose occasionally takes something as mundane as the zip-up protective case and makes it worth talking about, and that's the deal with the QC 25's included case. There's an etched diagram inside displaying how the headphones fold down to perfectly fit the case's slim contours, something other headphone companies would benefit from copying. A small compartment houses an extra AAA battery and the airplane jack adapter, handy things to keep on-hand. It isn't fancy, but it makes more efficient use of a small amount of space than most headphone cases do, allowing the QC 25 to be a better travel companion.
Performance
Bose's noise cancellation circuitry continues to be the best in the business. Although the in-ear QuietComfort 20 blocks out more ambient noise, the new QC 25 does an amazing job of shutting down the drones, whirs, and hums of modern life. You can still hear someone talking to you fairly easily when the QC25 is engaged; with the in-ear pair, someone could be trying to talk to you and you might not even notice. However, the entire QC lineup including this pair manages to simply be the best at reducing the constant clamor of work environments, planes, trains, and machines.
In passive mode, the treble and bass are both dialed back dramatically, along with the overall volume level. Switch to active mode to enable the noise-canceling feature and things get brighter, deeper, and louder. If there was ever a knock on the QC series, it was that the headphones didn't sound particularly amazing. Over time, however, the line has introduced more balanced sound signatures.
On tracks like The Knife's "Silent Shout," which has a tremendous level of sub-bass content, the QC 25 delivers quite a bit of low-end. The QC 25 doesn't distort even at top, unsafe listening levels, and the bass is intense. More moderate listening levels still feature plenty of bass response, but it's not quite as boosted as a Beats headphone pair.
Bill Callahan's baritone vocals have a richness to them that needs little help in "Drover," but the QC 25 boosts the lows and low-mids a bit, anyway. The drums get heavier than they need to, but again the bass boosting doesn't approach ridiculous levels.
On Jay-Z and Kanye West's "No Church in the Wild," the kick drum loop's attack gets enough high-mid presence to retain its sharpness and slice through this dense mix. The sub-bass synth hits that punctuate the beat don't get nearly as much low-frequency boost as they would on a heavier-bass set, but they still sound quite powerful.
Classical tracks get a nice low and low-mid boost that allows the lower register strings to stand out a bit more than they normally would. The high-mids and highs, meanwhile, stand out enough to allow the vocal parts and the higher-register strings to retain the spotlight. This is a crisp, clear response, with some flashes of added richness in the bass realm. It's the Bose sound: Brightness with bass, but not too much bass.
If the mega-bass experience is what you're looking for, the Beats Studio is a powerful option with decent noise cancellation, and the AKG K 490 NC is one of the best-sounding pairs with noise cancellation (but not the best noise cancellation itself) we've tested. If you're looking for the best noise cancellation available, that honor still belongs to the Bose QC 20 earphones. And if you're on a budget, but still want some decent noise cancellation, the in-ear Phiaton PS 20 NC offers a reasonably effective experience.
At £170, the Bose QuietComfort 25 is still a noise-canceling headphone pair first and a music lover's headphone pair second. But Bose introduces new improvements (like passive listening mode) with every model that keep QuietComfort on top of the noise cancellation market.
