Pros: Design, overall looks, long cable
Cons: Low sound quality
These headphones are not for a true audiophile person. If you just want to watch movies on YouTube and talk with your friends on Skype - they will do the job for you. But if you want to enjoy your favorite music don't expect that you can get much out of 30$ peace of plastic. They look good from the distance, but all materials have that cheap feel when you hold them in your hands. Comfort is acceptable though, they fit nicely around the ears, the only think that can cause discomfort is plastic bent that is on top of your head, sometimes it can really hurts and if you use them for more than 10-15min you can feel the pain on your skull! There are no soft materials on top.
I think that most reviews about these pair of headphones are dishonest, they glorify something that is just not true. Firstly, they are not loud enough, you can maximize the volume and still don't hear as loud as it should be. Bass is bad, weak, distorted. Middles are below awerage, highs are the worst of all! Sound is leaking like they are open air headphones, which they are not, and it shouldn't leak as much.
I just can't recommend them because I don't like how do they sound.
If you are a person with a limited budget and just need cheap headphones to play games, watch the movies, talk on Skype and look somewhat ''cool'' while wearing them :) - buy them, they will serve good enough. But if you want to listen to your favourite music look further, these will just distort your favourite songs and make them sound like cr*p.
