Pros Great sound, very accurate and natural sound, comfortable
Great noise cancelling capability
Cons Very loud tick when you have the amp turned on
Summary From the first moment I used these I could immediately tell that these headphones were clearly aimed at the upper end of what is quite a competitive market for noise cancelling headphones. You can tell straight away from even the quality of the packaging that this is a premium product. The headphones themselves are attractively styled (to me anyway) and are beautifully put together.
They come with a case and two sets of leads - one for MP3 players, and the other for smartphones. Interestingly, the smartphone cable works perfectly with my Samsung Galaxy Note 2 Android phone even though the included documentation seems to imply that this is intended for use with Apple products.
Basically, all of the advertised functions work perfectly, even down to answering calls. The phones themselves are quite bulky - compact they are not - but they fold up nicely and the enclosed zip-up pouch keeps everything together in your rucksack.
In use, I can't honestly say that I find the headphones heavy at all, even though the Boses are lighter. They fit comfortably over the ear, enclosing it entirely. These are serious headphones that can be worn for hours without discomfort.
There is something about these that distinguish them from the Bose QuietComfort 15s: an absolute clarity and transparency that, to be honest, I've never experienced in headphones before. I've also listened to the Bose QC15s and do like them, but there is an ever so slight veiling in the sound that you just don't experience with these.
There is absolutely no coloration in the sound at all and I am convinced that these headphones are up to studio monitor standards. I found them to be a delight to listen to and, as you would expect, you hear everything on the recording with highs that are sweet and free from harshness, gorgeous textures on mids, and deep bass when it's needed. There's not much to dislike here, if there is anything to dislike at all.
The lack of coloration and tonal bias does mean that, for example, if you listen to dance music, you will need to adjust the tone and equaliser controls in your music player to get the sound you desire - these are no Dr Dre's! That said, if you do boost the bass, these headphones will always step up to the plate, giving a good account of themselves.
For classical lovers, these phones are also just perfect and I have never heard such separation between instruments in heaphones as good as with these before! I am lucky in that I love both genres of music; be it Beethoven or the Prodigy, these headphones do deliver the goods with just about everything you put in them.
The headphones have a three position switch that controls how the headphones behave. In the "off" position, they are just like any other headphones and in this position they sound very good. The next position is the phones' internal amplifiers which does boost the dynamic range somewhat. Quite whether or not this represents an improvement over the passive mode I am unable to determine - the sound is different.
I'll leave it to you to determine what position suits you best. The third position is for noise cancellation. This works well and is generally quite effective, although not as ruthless in smothering out noise as the Bose 'phones. That said, on a flight, it almost eliminates engine noise and is ideal for passengers on other modes of transport too.
I can honestly say that there is nothing I really dislike about these headphones, and I recommend them wholeheartedly to anyone who wants peace and quiet on a plane, or just good music in the home without disturbing those around you. Basically, these phones will appeal to everyone who travels frequently, and who value good audio quality.

I hope my review is helpful, enjoy!
Pros I can't find anything that I like about this product or the company.
Cons heavy, cancels bass sound by adding hiss sound, attachment broke, and the company was not interested in trying to fix the problem. Squeezes the head. Announcements from the cabin crew on airplanes is ear-splittingly loud!
Summary You'd be crazy to buy these without trying them first.
