I got these headphones because the AC in my room was too loud at night. They took a bit to get used to, but I love them. At the price I paid I was very worried I wouldn't like them or they wouldn't work, but they're great.

Comfortable

Poor Value; Too Much Ambient Noise

"Pleasantly surprised! First use yesterday on flight...the sound was excellent while completely cancelling out all backround noise. Earphones make my ears hot and can affect my earrings (depending on style). No problem with the ear bud!

These headphones are great certainly not cheap but you do get what you pay for!! Ordering through Argos fast track was super easy and convenient being able to collect at a time that suited me. Would not hesitate ordering again!

Noise cancelling technology is even better than ever; much better than my previous over-the-ear style and small for traveling. A must have for flights. I hope the cable is robust coming out of the main unit; being repeatedly shoved into the provided pouch that is barely long enough might run it's...

Does exactly what it says noise cancelling is brilliant sound is excellent

Nothing yet only had them since Christmas

I also have a pair of QC 15 headphones which I love but was amazed to find that the QC 20 is even better in comfort, sound and noise cancelling.. these are now my "Go To" headphones.. 5 stars

-In very loud environments the noise canceling will start to make slight popping sounds, but again, only in VERY loud environments. -Overall great product, even at $300 I would recommend these.

-Very comfortable, can wear them for 3+ hours with minimal ear fatigue; Earbuds fit nicely into ear; -The noise canceling is excellent; They are very effective in blocking out constant background noise such as the airplane or office environment.

-The battery being located right next the headphone jack is a little annoying, would have preferred it a little further down the cord; -The included carrying case is a little small

Yes, it's a lot of money for a pair of earbuds, but if you travel a lot especially on airplanes they are great. I can't say the sound quality is in that price range, but it's more than just about the sound. They are lightweight, not bulky like over the ear noise canceling headsets.

Noise-cancelling in-canal earphones have been far less popular and common than the on-ear and over-ear ear noise cancelling full-size headphones, like Bose's QuietComfort 15 . With the QuietComfort 20, Bose aims to change this.

The best noise cancellation circuitry on the market; Rich bass response and crisp highs; Comfortable, secure fit; Works in passive mode

Sound signature is very sculpted, and not for purists; Light on accessories like extra eartips

It is really hard to find any good headphones that offer such high noise cancellation and yet provide rich sound in such a small form factor and for these facts, the price of ￡259 appears to be justified for the Bose QuietComfort 20i.
