Pros: Clear bass, excellent build. Lively presentation.
Cons: Overly bright. Synthetic sound.
Very good headphones if you want something fun, lively and bassy. I was really impressed at first but with time I started to notice the short comings. Although relatively open sounding the sound is quite synthetic, almost forced. They do not give an accurate representation of the material listened to but that is not to say they do not give an enjoyable performance. Bass is well defined and lively, maybe too lively.
If you are after some 'truth' in your closed back headphones then I would steer clear of these. If you are looking for something fun then I would recommend giving these a try!
