All I can say is Wow. I've had headphones from Audio Technica, Shure, Sony, etc., all around $100+. They are almost as good as the aforementioned in terms of tone, separation and clarity. The low-end is where these headphones shine. The bass is nice and tight without having to do without mids. The hard case is comfortable, the extra silicone ear cups ensure a snug fit, and the loose Comply memory foam ear tips are great for boosting bass and helping with noise isolation. The only complaint I have is that they require a lot of power from an external source. My SanDisk MP3 player volume was turned up to maximum at the gym to make sure it was loud enough. At home on my computer they are fine. These headphones are highly recommended. They're a good deal @ $75. I even bought my girlfriend an M50 and she loves it.
