I am a recording engineer/producer and I owned a pair of these in the 80's and literally wore the pads out to the point I had to toss 'em. Back then, we had no internet or Amazon and I was unaware if I could even get replacement pads. I always thought I would just buy another brand new pair from the pro music shop again(which is where I bought them initially) but just never did. I remember it was a sad day when I threw them out.I remember one time when one of the pads finally completely gave up the ghost and I wore them throughout an hours-long mixing session to the point my ears were losing skin and near bleeding because of rubbing on the hard plastic grill. Ouch. Yeah, I loved them THAT MUCH for mixing along with my Near-fields.Anyway, I got my new pair today, shipping was super fast and OMG... how have I lived without these for so long? They sound better, in my opinion, than my $350 pair of Sennheiser's I've grown so accustomed to for the past decade or more.There is a reason these have been, and will remain, an industry standard in studios all around the world. They have an amazing flat response yet maintain such a rich sound at this price point that you just can't beat them if you are budget-minded like me.I HIGHLY RECOMMEND THESE HEADPHONES for clarity and equal separation of frequencies across the full spectrum for engineers looking for a great mixing/referencing set of open-back headphones.BTW, I HAVE used these for tracking vocals as well without problems. (Even though so many people say you should never do it) Just turn 'em down a bit and with some simple fade-in/fade-out editing wizardry any competent engineer can do on vocal tracks will make any noticeable bleed disappear if you know what you are doing in your DAW. A lazy producer will yield lazy-sounding productions. There's no need to even mention "bleed" if you pull up your big-boy pants and DO some simple fade-edits.These headphones are way to comfortable and sound too good to just write them off as a pair of "never use for tracking" headphones because of "bleed".It is a great day in my world today! I am SO HAPPY with this long overdue re-purchase of this incredible product. I have missed you my old friend! Indeed I HAVE!
