I'm just looking for a headphone that gives decent bass and good sound quality for every music genre. I know a coworker who has the Monster headphones (not Dr. Dre) and he said they were pretty good
i listen to hip hop, electro, a little classic rock, and a little dubstep and I can tell you now that you're just going to be complaining about your beats that you're going to buy.
For starters, they get uncomfortable to wear after about 30 minutes. Find something with a little more padding (such as the XB700's i posted earlier, perhaps).
Just by looking at specs, the beats aren't very good. The frequency ratio is pretty narrow in comparison to other headphones at that price, and the bass power isn't actually very well either (the XB700's pack a wider hertz and ohms ratio as well).
Also, you said that "somebody else has Monster headphones": as posted above, Monster doesn't manufacture beats anymore; you won't find their name on the box, or headphones of the new ones. As far as I've heard, they're just as bad as the old ones.
You can go ahead and waste your money any way you please, however I can tell you that you're going to be dissatisfied with Beats in 3 weeks, one week past the return date, and they'll be up on craigslist.
For those wondering, I have tried Beats Solos(on ear feels terrible), Studios (not enough padding, feels like its pressing against your head and gives you a headache), Pros (waaaaaaaay too heavy, and worse than the studios in my opinion), and tours (break in a week. Not worth your money.), so I have quite a bit of experience and knowledge of the brand.
