Pros: great perfornmence..low cost

Cons: a bit loud fan in my opinion..

Overall Review: great upgrade...i have dell e521(the old one)..working lika a charm..no problem so far..easy to install..just take ur computer apart nd put it in then install da drivers..(may have to disable ur onboard graphics,thats what i did)..overall performance is good so far..games like css, hitman,flatout 2, batman(the new one) can be played on max settings..try blu-ray pretty soon.

Pros: Long lasting; good cheap quality; when bought was 13 bucks

Cons: not very sturdy, meaning more towards the fragile side. careful where u put it.

Overall Review: cant believe within an year this headphone rose price from $13 to $37. thats more than an 100% rise i product cost. insane i would not even think about buying the headphone at that price. under $20 was most realistic value for this headphone
