Audiophile Needed: I got the Sennheiser MM 400?

[Genxi]

I just bought these off Ebay, and I'd like to know how this pair of headphone fare when compared with the Sennheiser HD headphone line. Also, please tell me how much more better this headphone would be compared to Dr. Dre's Beats!

Thank-You


P.S.: I like to receive confirmation on my buying decisions, haha.

I'm not an expert for sure, but i know for the fact that the beats by dr.dre are overpriced and sennheiser matches the quality no doubt .
