I don't really wanna bash on the beats,and I admit they look fantastic IMO,still yet to find headphones that look more stylish.
I would say the headphones are decent at best.They're good,but not for the price you pay for em.Maybe if they cost below $100 then they'd be worth it for the sound quality(the studios).
And when you said you're getting these from your collegue,what do you mean? Is he buying you a new pair or is he giving you an old pair of his? or selling? If he's buying you a new pair then go looking around for a better pair of headphones from other brands(namely Sony,Audio Technica,Grados or whatever headphones you see people talk about on these forums.)
If he's giving them to you free then go for em,they look sexy as hell.
And as for detox pro,not worth paying and extra $100 or so for an all black color scheme.
