These headphones sound very precise and balanced. You will hear your music as it was recorded, mixed, and mastered which is the approach I prefer to trying to find headphones that try to EQ things for you. I listen mostly to metal, jazz, synthpop, and instrumental music and the On1s have impressed me in everything I've tried. They can get very loud when powered from a PC and sound great straight from my Nexus 5. The wood used to make the cups is very beautiful and pleasant to the touch. They change color slightly depending on viewing angle and lighting which is cool; much more classy than red and white plastic. The headband is comfortable and quite durable; you can find a youtube video of it being stretched and twisted to no ill effect. The included cables are also pretty. The one with the inline pause/play and microphone works well for phone calls/skype when used with a smartphone. They also did a decent job of muffling noise while I listened to podcasts on a flight recently. Strictly passive noise cancelling obviously, which may vary in effectiveness depending on the size and shape of your ears.
Some things to note: they are quite comfortable but can cause some irritation if you wear glasses with them for long periods of time. I've found that moving my glasses up a bit sidesteps that issue. This issue is inherent to on-ear headphones, so nothing against this model in particular. While the braided cables are pretty they can cause some noise when rubbed against other fabric surfaces, such as my shirt collar when I'm sitting at my desk at work. This can be avoided by using a different non-braided cable or by not wearing shirts with collars I suppose.
Ultimately I think these headphones are worth the money as they sound, look, and feel great. Those who appreciate quality, unbiased sound across wide varieties of music and portability will find their money well spent on the On1s.
