The Sharp HP-MD33-S.
I bought mine from
www.bluetin.com for 25 pounds. (great service, 5 days post)
Note that I've never heard the Shure E2c or Sony EX71, the most similar types of phones, but compared to the SR60s, besides the fact that they are earplugs, (which brings with it a slightly different sort of sound, which I'm not sure that I prefer), they are as articulate, less bright, have only very slightly less bass impact, and extremely careful listening does reveal that they are less resolving.
The bass is perceptibly muddier though, but because of the isolation they are actually preferable for most general portable use; are easier to carry around, are extremely comfortable, and are preferable to me for most classical/jazz music. They are comparable cans, and I might decide to liquidate my SR60 because I foresee that I shall be using it much less.
Note that they actaully have more bass impact that my KSC-50s, have slightly less muddy bass, seem smoother, have a tad more resolution and overall are definitely preferable. I do prefer the SR60 to the KSC-50, mostly because of the greater bass kick, and these seem firmly in the middle. (and I'm keeping the Kosses cuz they are nice to exercise with)
(I'll probably do a more through review later, this is very much "first impressions", I'd actually created a post like this yesterday, but my internet connection crapped out.)
This was straight out of an iPod, with LAME 3.90.3 APS files.
