Very happy with these headphones as they sound wonderful and have just the right amount of noise cancellation for me.
However if you wish to use a mic such as modmic or vmoda (as I do) you have to open the headphones and slightly modify them (which is pretty straightforward and there are many tutorials on youtube)

As someone who works in a studio very frequently, the Sennheiser HD 598 are a very good pair of headphones. The 598 are cheap and are better than 95% of the other headphones on the market. Their quality is far greater in terms of sound quality and they are quite sturdy too. The only reason these may be less attractive to buyer is because of their looks.
Great product.
