Well, I use em, but I don't think that should count as a ringing, unbiased endorsement.
As far as the differences, that's easy:
The Studio MoreMe headphones have a built-in 1/8" plug with a 1/4" adaptor. The Studio Deluxe headphones are straight 1/4" - no adaptor.
The Studio MoreMe headphones have a simple plastic headband. The Studio Deluxe headphones have a thick padded headband.
The Studio MoreMe headphones have a slight midrange peak. The Studio Deluxe headphones have a 1" thick damping pad inside each can to smmoth that peak out.
The Studio MoreMe headphones have Red=Right and Blue=Left stickers and a small white L or R sticker. The Studio Deluxe headphones has the Red=Right and Blue=Left stickers, big Blue and Red round stickers that say "Left" and "Right", and a giant "L" and "R" imprinted on the ends of the headband.
And finally, the manufacturers "say" the Studio Deluxe MoreMe's go down a little lower, and up a little higher (20Hz to 20kHz), as compared to the Studio MoreMe's (30Hz to 18kHz).
Most people have said that they are pretty good sounding phones and they were pleased with their purchase. (I think a few people were "quite" surprised by how good they really were.) Just about everybody agrees that the musicians that have used them were very satisfied with them for tracking.
Quite a few people have returned to buy more of them. Every reviewer I've sent them to also likes them.
Finally, we have a dealer (
