Summary: I'm not an audiophile, but I do recognize and appreciate good sound. These headphones have surprisingly good sound for the price. I mostly use them to listen to music on my computer at night via iTunes - I adjusted the iTunes equalizer to get the sound where I want it and get crisp, clear highs, good mids, and strong but tight bass. They aren't noise canceling, but they do muffle outside sound pretty well.
Summary: These headphones are a good deal for the money. I have only 2 minor complaints. They are a tight fit and I have a small head. A person with a large head may not like them. The other thing is the cable on them is thin, and you need to be carefull not to crimp or bend it too much.
Summary: Overall good headphones for the price. The over the ear design is decent for those with ears that aren't large. Isolates sound pretty darn well but I have to see what the comfort level is when wearing these for long durations. So far 3 hours is good. The construction could be a lot better but again for the price ($25), you can't really complain. The ear cups can come out so for trips, it is possible to safely pack them away.
Pros: Great deal for the price, the sound is awesome, nice bass overall it is a great headphone compared to the price.
Cons: After a year of using it the wire that connects to the plastic on the right earpiece snapped. It could be due to normal wear and tear but I do feel that the insulation of the wire is a little bit thin. After 2~3 hours of wearing it it causes some discomfort on the ears.
