These headphones suck. I really wanted to like these, achieving a perfect seal with comply foam to get the maximum experience. Plugged into an iPhone 4s, the bass isnt nowhere near as good as the monster turbine. In terms of overall sound, these are not bass oriented earphones. Selling them right away. Don't believe the youtube reviews that the MG7 drivers deliver thumping sub bass. They have zero bass whatsoever. I'd give them a 0/10 max.
I'll buy them from you. $50 bucks. Or you have my Turbines in exchange, since it seems you enjoy them.
