Pros: Highly Modifiable, low price, smooth sounding
Cons: Lacks sparkle in treble, ugly
These headphones are great in the sense that they are the ultimate modding headphones. You can adjust the sound to almost anything you want with a few relatively simple mods.
Before modification, the resonance is horrible, the headphones are all mids, and nothing else, but the sounds is smooth.
After modification, the sound remains smooth, but there is an obvious increase in treble and bass to balance out the sounds. The treble does not have the necessary sparkle that I would want from it, but it is a matter of skills, I am sure someone out there has the ability to mod these things to provide smoother and better sounds.
The headphones are relatively ugly (nothing you can do about this), and is quite uncomfortable unmodded, but you can increase the mods (change the ear pads, add comfort strap) to significantly increase the comfort.
Overall, a bargain of a buy, and it forced me to learn more about how sound works in headphones and in the orthodynamic technology.
