Used these for half a year and thought these were absolutely fantastic until once tried the much cheaper Sennheiser HD 200
Pro. In contrast with the Sennheisers the sound of SRH940 is very unbalanced, with over-the-top highs and rather bleak lows. Such a distortion may be good for casual listening but not for mixing and mastering. To much of my surprise, with the Sennheisers I managed to hear much more subtle nuances in my mixes which I could not hear with SRH940. I don't say these headphones are bad, they are decent and much more comfortable to wear than the cheap plastic Sennheisers but their sound is certainly not great, at least it doesn't worth the price, although they come with a fine case and a pair of detachable cables (Sennheiser HD 200
Pro's cable is not detachable). I think Shure is an amazing brand when it comes to mics but it seems their headphones are nothing but okay.
