Ehh 3.5 stars with 37 reviews. I own Monster Beats Solo headphobes personally and they're ok but nothing overly impressive.
Why would you compare Solo's to anything but necklaces.. cause that's all they're good for. Hanging around your neck.
Personally, I think I MIGHT shoot for these Turbines, cause Head-fi will not give praise to Monster/Beats unless it's deserved.
