I have, as many of you out there in studioland, have at least four varieties of headphones. I like to mix at time in the cans. Sometimes it turns out impressive and sometimes not. I bought the Shure SRH940's for the reviews. I gotta say I was deeply impressed. At first listen was something I recorded that had a harsh high end and didn't show up on three different high cost headphones. My monitors revealed this flaw. Then used the Shure 940 to see the difference. I found the culprit from the get go. Also heard things I didn't on my trusted monitors. That was enough to tell me, these headphones do the job properly and are extremely comfortable and built quality is very good. I highly recommend these headphone.
