4 out of 5 eggsMore than decent headphones.

Pros: Slightly comfortable.
Very nice sound quality.
Mike is detachable if you don't want to use it.
Nice design.
Very nice for the price.

Cons: Tends to compress around the head. Just a little tighter than it needs to be.
A little light, would prefer one with a little more weight to it.

5 out of 5 eggsExcellent Product

Pros: -Extremely comfortable
-Removeable microphone
-Line remote controller
-Price for what you get

Cons: Non

Other Thoughts: I juggled between various headsets for a couple months and decided to go with this pair. While Cooler Master is typically known for their PC cooling products the looks of this heatset for the price could not be beat. The headset seems durable and is not made of cheap materials. It's a very comfortable headset and while I haven't worn it for an extended amount of time, I can't see the gamer's headet pain coming into play. Would recommend to any friend.

Manufacturer Response:
