    Good sound and Noise-Cancelling.

    Could Be Five Stars Easily

    • Written by from APO

    First... Awesome. They work! Nine and half hour flight to Germany and back and I could not be happier. Battery lasted the entire flight. The headset was comfortable except for the cord length. I also use the 20i's at the gym. They stay put. Again very comfortable. Almost too comfortable. They sit very "light" in my ears. However, the cord length from the "Y" is too short and can't be adjusted. The audio jack end also has the small flat and thin NC electronics module with not much cord. Because the cord is so short the module dangles in my hand as I am trying to text or take notes on my iPhone. Just a few more inches of cord on both ends would have helped the 20i's garner a solid five stars. While running and working-out the short cord length twists and tightens pulling on each ear piece. Even with the cord clamp fixed to your shirt. While stationary you don't really notice the short cord length, however, with each cord coming from the earbuds tend to ride on the side of your face. Not really noticeable accept in prolonged use (like a mentioned in the opening). The audio performance was great using both my iPhone and the Delta 767 audio port.

    4.5 stars... So good I can't hear s***!

    • Written by from LONDON

    I have owned a pair of MIE2i for a few years and they were very good, I loved the StayHear ear-tips and good quality sound (although they didn't quite go loud enough for me). Therefore, I didn't have reservations upgrading, was it worth the money? YES!

    Sound quality: Not amazing but very good! Unless you are a complete audio snob then they are fine. You will hear a faint electronic hiss of the noise-cancelling if you have them 'on' without playing music but don't notice it once playing music. The aware-mode is good for crossing traffic or wanting to talk to someone, it basically cuts off all noise-cancelling.

    The noise-cancelling itself is awesome! Fantastic reduction in background noise, great for riding the tube/metro/train/bus/plane! Walking along the street, buses quietly whoosh by and most cars now seem like silent electric ones and the person at the bus stop asking you a question seems like they are just miming song lyrics... until you embarrassingly realise they are talking to you! These make walking around feel like you are on your own Planet... population one...
    Use an adaptor and these are brilliant on a plane too.

    Design flaws / things to get used to (why I didn't rate 5 stars):

    You have a short cable that goes from the battery pack to your iPhone, then the long cable going from the opposite end to the ear plugs. You get used to holding your phone with the battery pack behind it so it is not dangling around if they had 'mounted' it halfway along the main cable. I am concerned about how long the cable ends will last, I eventually damaged one cable on my MIE2i going into an ear-piece. Problem is, you have to take the battery pack out of your pocket along with your phone every time, therefore increasing wear and tear on the cables.

    Don't forget to turn it off when you pack it away or it will continue to work away.

    The remote is positioned at the Y-junction of the main cable where it splits to the separate ear-pieces. I always run my cables under my shirts/jumper so it is not dangling around, now the remote is buried under my shirt so not as quickly accessible as the MIE2i remote (functions still the same) which dangled down from one ear but was accessible. Obviously this won't be an issue if you wear your cable outside your clothing (where it catches on things and you're advertising to would-be thieves).

    Conclusion, just buy them, enjoy walking around in your own quiet little world and just put up with the minor functionality issues, they are actually well designed as you would expect of Bose.

    Whats with all the Hype?

    • Written by from Manchester

    I love Bose, Bose create some of the best sounds from all types of media, but for me the In-ears have always ben trouble, i've had almost 4 replacement sets on Bose In-ears and opted out on the last pair...

    however after much thought making i decided to return to the sound i love and make the big purchase of the Quietcomforts... basically the sound is there.... but just so low... if you are expecting these to be loud, even with Noise cancelling activated then you will be disappointed.

    they seem to compensate the lack of loudness by the noise cancellation, but the noise cancellation only works on simple static sounds, IE the sound of an engine, humming etc... so they are perfect for travellers etc... but because they feel so plasticky they do let a lot of sound in

    the other issue is the huge Battery flat pack that you have dangling from your iPhone, the size is the exact length of an iPhone 5 screen, and if you don't have it charged then the noise cancellation wont work and you are stuck with a really awful tinny sound from the headphones... certainly not worth the £259 you just spent!

    If your going to spend this sort of cash, you will want a wow factor, and I will just say that you wont get it there is a lot better in the market and for a lot less the price...

    Amazing Headphones

    • Written by from Oxford

    I bought these headphones when they first came out, and I am in love with them. Great Bose quality, shows the 25 years of experience. Only complaint that I did go through 5 pairs in a few months because of the cord coming out of the battery pack. Bose was great about it though they have a great warranty and sent me new ones when mine would break no questions asked. I say that but they are durable headphones they only break when the cord would get caught on something when I was walking a door handle for example. Overall great headphones!

    Amazing PEACE of Mind

    • Written by from San Jose

    I live in a noisy apartment. Since Bose is known for acoustic excellence, I decided to try out the QC-20i. The price is high though worth every cent. After purchasing these, the moment I flipped the ANC switch, my noisy neighbors vanished. This alone is worth substantially more than what I spent on these. Music sounds excellent as you'd expect with Bose; ANC is a bit flaky in that it impacts sound quality slightly though Bose has done better than anyone else is minimizing this impact. The PEACE of mind the QC-20i's provide me with from the urban sprawl I live in makes these one of the best investments since I moved here 5 years ago. Finally PEACE and QUIET when I want it!

    Excellent noise cancellation

    • Written by from Bournemouth

    These headphones are expensive, but the sound is great. I tested these walking down a busy London street and could not hear the traffic. They also feature an "aware mode" that allows you to hear some background noise. The only downside is that the noise cancellation module has to be kept next to the phone and you can't turn of the NC feature from the remote. There is an extension cable available which I've yet to test. I used my own Belkin high quality extension and there was noticeable sound distortion, so I guess there's a reason why Bose charge £10 for the extension. I listen to an eclectic range of music and don't like to have too much bass, so these are perfect. The sound may not be the best available, but the noise cancellation more than makes up for that. I'm now looking forward to using these on my next flight.

    These are fantastic noise canceling in ear headphones. I fly a lot for work and it drowns out the drone noise of the jet engines. Keep up the quality product producing, Bose.

    First ear phone and so pleased

    • Written by from Hackney

    Like others I was concerned over cost and to a point which I valued more music quality or noise cancellation . As this was my first dip into earphones and because I was on holiday and had time on my hand I did some research and shopped around in Florida to see which suited me more. My final decision was the qc 20i. After purchasing and charging I did a 8 hour drive from Daytona to Tampa and back . I had the windows down and the 20i connected to my IPhone where I had downloaded some music to.
    The drive was a dream , earphones had cancelled out all road noise you could however still hear if someone blew their car horn so safety was not affected. If you received a call while playing music the volume would reduce automatically so that you would only hear the ringing of your phone .if you decide to accept the call just press the button on the lead. Once the call has ended the music will automatically come back on.
    I then had an 8 hour flight and again the background noise was canceled but to a lesser degree. Battery life was more then adequate.
    Overall I prefer to use mine on motorways . On long drives through country roads. Excellent and very happy with my purchase.

    Awesome sound but some functionality and compatibility issues

    • Written by from Heanor

    While Bose is at the top of the chart for noise cancelling technology, I couldn't give these headphones 5 stars for the following reasons.

    1. When the battery runs out, the sound keeps going (Bonus over QC15) however sound quality is seriously degraded. Not so bad considering the battery life but if you are on a long or double flight, you better hope for USB on the plane or bring a usb battery.
    2. The short 90 degree jack is a bit difficult to unplug to the point of needing to dig fingernails into the rubber to pry it off
    3. Not compatible with smart case (at least not with iPad mini smart case) - the hole is just a bit too small for the jack. Apple doesn't appear to offer any official extension that supports the microphone / volume function either making it tough to combine the iPad with excellent protection from the smart case AND these amazing earphones
    4. The battery pack can be a in the way, especially if you want to tuck your device into a pocket or even walk with it as it tends to dangle and since the jack is at a 90 degree angle, it will pull on it slightly - recommend folding it up against the back of the device perhaps but then you'll find it tricky to take it out say if you had it in your pocket.

    So sound quality and noise cancelling - top notch. Execution / functionality unfortunately needs some work. The fact that it is not compatible with the smart case is simply silly especially in an airplane when you want the stand functionality as well as the noise cancelling.

    It will surprise you. Stunning!

    • Written by from Edensor Park

    I own a QC15 which I found to be most comfortable after trying many noise cancelling alternatives (including the QC3). I bought an Mie2 to replace my previous in-ear earphones for wearing on short trips such as the train etc. When I saw the QC20i, I knew I had to try it and I expected it to be as comfortable as the tips of the Mie2.

    The QC20i tips have a snugger fit than those of the Mie2. Having used them for extended periods now I can say they remain comfortable because they don't push into the ear canal. Only catch is I still find myself pushing the extended bits into the grooves of my ears when I put them on.

    The thing that amazed me most was the noise cancelling. I found it superior to the QC15 which I thought was already pretty good. The snug fit of the tips probably helped block out some of the noise.

    The best part for me is the QC20i have replaced both my QC15 and Mie2. The size of the QC15 and its reliance on battery makes it inconvenient for short trips. The QC20i will pass through music without having to be turned on which means I can use them all the time and only turn on noise cancelling when needed.

    I have been recommending these to anyone who asks and work with many colleagues who are also happy owners. It's well worth buying, even with the considerably high price tag.

    Had these for six weeks now, they are comfortable over long periods (like 14-hour flights), they stay in place in the gym and the noise cancellation and sound quality are superb. Battery pack is a little strange but easily managed. I'm very happy with them.

    If you are realistic about what you want then these are the best headphones

    • Written by from Dublin

    I spent about 2 months researching tens of different headphones and after I decided that the noise cancellation is the most important for me I decided to go with bose 20i. Mainly to silence noise in the office, library and the metro.

    I have to tell you, I did not know what to expect exactly, but I assure you, if you never tried any noise cancellation headphones before you will be blown away the moment you turn these ones on. I just cant believe how good the noise cancellation is, especially when the music is off!!! I can only hear something if someone talks really close to me. The sound quality is top class, obviously the noise cancellation affects the sound quality slightly but if someone is looking for headphones purely to get the best sound quality then any noise cancellation headphones are a bad choice.

    Bose QuietComfort 20i cost me 299 but they are worth it, the build quality is top class.

    I bought these after reading all the positive reviews. However, after trying them for several hours, I took them back to the store. I really don't like that ear plug feeling, and the noise quality is not what you would expect for this price.

    Ever So GOOD!!

    • Written by from Faversham

    Its difficult to believe just looking at them but "my lord" these things are good, sound is excellent, the noise reduction is something you will have to try to believe reviews cannot do them justice all this without the bulk of Over/On the ear headphones. What i will write is, they turned a noisy and crowded London Tube journey into something pleasurable, and as anyone who takes the London tube will know thats virtually impossible. I recommend these highly, expecially if you commute or travel in noisy environments.

    Great sound, comfortable

    • Written by from Esperance

    Love the sound from these and the noise cancellation works very well. Also the fact you can use the aware mode so you can hear some outside noise when you need it and the fact that they work great even with a dead battery is good too. My only complaint is the short length of cable between the battery/signal processor and the device you have it connected too. Otherwise would have been 5 stars from me.

    Not good for sports

    • Written by from Inglewood

    These are no good for sports or outside use with wind. I brought them as I assumed they would be great for riding my bike to isolate out the noise of the traffic and so forth. Unfortunately they do not hand wind noise at all, in fact they take the wind noise and amplify it through the speakers making it impossible to listen to the music. These are great however in the house but I have a pair of QC15 for that. Going to see about a refund.

    A little disappointed

    • Written by from calgary

    I got this because there were many positive reviews for this headphone.
    Especially regarding noise cancellation.
    I tried it at the store and it felt good for those couple of seconds.
    When I actually got my pair, I really feel that it's overrated.
    It's not that comfortable because my ear can feel the pressure, it's the feeling of an ear plug.
    I really don't like that ear plug feeling.
    In a quiet room with air ventilation, it is possible to hear this dull weird hiss.
    You can still hear yourself typing, other music playing as well as other voices.
    I found review saying that this earphone does not work with wind, I haven't tried it personally.
    I will test this for a couple more days, may end up returning this.
