Query: Good Buy

Great headphone. Big bang for the bucks. I'm try this head phone at CES and totally sold the second I heard it. Very good sound. Don't waste your money on other type of headphone. I'm try alot of headphone and this is the best value for under $200 headphone. My friend regret buying a $150 Bose headphone after hear this Koss. My though is if you not a pro DJ or artist, there no reason to spend too much on headphone. This head phone very good for everyday use. I'm personally recommend Koss and Sennheiser headphone, great price and good sound.Pro: good sound, reasonable price ( I think it a bargain). Life time warranty.Con:Your hair will stuck in the head mount if you not careful.Open air head phone, sound will leak to surround. Not recommend for library using
