Frankly superior.
Excellent isolation. The sound quality is wonderful, clean, clear, crisp, mids are wonderful, not overly bright, with variable bass which you can adjust from very neutral and thin to monstrous levels, and it does the monstrous levels of bass on it's setting quite nicely without distorting of flubbing, it actually sounds nice, a little loose, but very meaty and visceral. Sound stage is excellent, better than the Vmoda & M50. Comfort is better too, bigger, deeper cups, and the faux leather material is swappable, big, thick and very comfortable (and can be changed to velour or microfiber at your leisure). Headband is swappable. Cable is detachable. It doesn't need an amplifier at all, it's 16ohm and can run from a potato and sounds wonderful without an extra expense tagged on, from your phone, from your desktop, doesn't matter. The switchable venting system that controls bass response is excellent, it works well, it's not just a gimmick, it's just a vented port that you can open at various radius and close, it's very durable and clicks nicely, feels stable and not like junk plastic. Cable is short, not 10 feet long, so great for portable and home use (and again, detaches and is replaceable if you want). Plus you can swap decals, the plates come off, and you can put different aluminum inserts (I got the carbon fiber looking one it's sweet) to make it as stylish as you want.
The COP is generally $150 and frankly, is something I recommend over the typical stuff at this price point because it just has features that other headphones lack while still having excellent quality and so much customization that really works and isn't just gimmick. Beyer really did a great job with this portable/studio/home use headphone and it's fantastic for production and casual music alike the way it's ports adjust. Great for a basshead, and great for someone who wants a neutral headphone, it's actually able to do both just fine and does it well.
Very best,
