Whew, tough question for me to answer.
As I said on my website (
http://moreme.info), I've got a bunch of dead 7506's, and that was one of my main problems with them.
The MoreMe's don't have the real bottom or the sizzling top end of the Sony's, but I found that most musicians didn't really care about that; they wanted LOUD - and more detail in the upper mids. The MoreMe's do that. They can get pretty damn loud.
I treat headphones as "disposable items" in our studio, but at a hundred dollars a pop, I was going thru Sony's way too fast. I found the Radio Shack "Hall Of Fame" (made by Koss) headphones at $40 each, but they sounded terrible and broke even faster. (For 3 years, I didn't care if they broke because I had the extended warranty, but they stopped offering the extended warranty.) But, after the extended warranty deal ended, I was back to square one; find some phones that were cheap, loud, tough, and with decent isolation.
After buying a ton of different headphones, I found these. They were made for institutional commercial use, like listening to cassette decks in classrooms. They met most of the criteria; they were cheap, loud, tough, and with almost decent isolation. I added some padding in the earphone cups and they sounded pretty damn good. The short 2 foot cord turned out to be a blessing; you can't step on it. Snag it, and the end simply disconnects.
I tried to talk Guitar Center and Sam Ash into carrying them, but no music stores were interested in them. In order to get a decent price, I had to buy a large quantity of them - and that's how MoreMe's headphones came into being. Since nobody was interested in selling them (including the distributor) I put my name on them and decided I'd sell them the way I thought they should be sold. That's where the" try them for a month or so", 2 day shipping, and the weird warranty came from. It's the way I think a company should do business. No gouging people on shipping and "handling" charges, a no bullshit warranty, and superfast service (without all the BS paperwork, or waiting till we receive them and test them).
Do they sound great? Hell, no, but they're good enough to work fine for tracking, even for drummers. Southern Tracks in Memphis ordered 5 pair and love them. There are some other big studios and people who love them (Bob Olhsson, etc.), but I'm not gonna mention names till I get their ok to do so. Fletcher has even recommended them if you want cheaps. I consider them to be like the cockroaches of the recording industry.
That's about as honest as I can be. Buy them, try 'em for a month or so, and if you don't like 'em, I'll give you your money back.
