It's been a long time since I posted here. Since having received my ED10s I've found myself listening to them a lot--and I mean a lot. In fact, right now they probably get more use than anything in my collection, except maybe for my Havi B3P1s. They have utterly spectacular sound quality in general, but once you factor in the price (I got mine for < $10 USD *including* international shipping!) their value skyrockets outrageously.
Seriously, in terms of performance-to-price ratio these things might be the best IEMs I have ever heard. They've even got great instrumental imaging and a fascinating sound stage that I find is deep and tall, like a corridor, without the Havis' cavernous width. They really do create a remarkable sense of depth in my music.
The one thing I cannot stand about the ED10s is that the cord, while very well built and behaved, is too short. I can't carry my DX90 in my pocket while wearing my ED10s because the cord is strained to the point where the IEMs will pop out of my ears too easily. Even with that minor gripe, the ED10s get an easy 5/5 recommendation for me at their price range. Unless you're the kind of person who has already invested huge sums of money into outlandishly high-performance gear, you'd be doing yourself a disservice not to pick up a pair of these things. (And even then, they allow you to take great sound on the go without fear of what happens if someone steals your backpack or whatever.)
