I'm always on the go with my headphones and this pair is still going strong. It has never tangled up and not deteriorated one bit. The price is excellent for the sound quality. No overabundance of bass and an excellent all-around headphone for different music types.

The only thing I do wish was that the although there are 3 different sized rubber caps for the ears, I do wish there were other sizes as well.

PROS:
These are really nice-looking headphones.
Perfect For TRON fans, which are also music enthusiasts.
Sound is really good once you manage to fit and isolate the headphones. Great bass.

CONS:
I don't feel they fit for daily use needs.
These come in relatively big design size, and this design makes it hard for you to fit them comfortably in your ear. The plastic excess that rests on your ear comes to be just too much after 30 minutes of use.
I usually wear headphones for 2-3 hours long a day, and these definitely wear me out very fast.
If you don't fit them well to your ear; and isolate them well, sound becomes poor.
The three sizes for ear plugs are quite generic, and I came into the problem that, if I use the smallest one, It won't be well isolated, and If I used the medium one, it would be too much in 30 minutes.
The large ones, are definitely unusable.

OTHER THOUGHTS:
Sound is definitely a blast, but sadly, in my experience, not very comfortable for heavy use.
