Uhh.. Which Beats?
And what exactly do you mean by "good or bad?"
If Beats (even if they are the Tours), were priced 60%-75% less of their current market prices, I'd definitely get a Tour and a SoloHD. Studios, maybe, but probably still no since it's only a fashion statement for me (don't like its "functions").
Oh and I'm assuming that you're only referring to the Beats line, which DOES NOT include the Turbines.
