I have heard the e500 and se530 both before. now Shure claims that they Share the "SAME PARTS" but truly they don't...well not exactly at least. I listened for a bit and instantly noticed that the se530 gave more kick in the bass, and much more consistent and warmer. so...i took both apart. ( DON"T WORRY I PUT THE BACK TOGETHER AFTER) and i found that what they did was smartly Vented the triple balanced armatures. or so what shure called. Tuned Bass Port. when you do this, it give more ventilation for the drivers. giving it more air to move. so this increased the overall sound quality. the shure se530 are the same price as the e500pth. there are two versions of the se530, the normal, and the pth version. the pth version is the same price as the e500 and the normal is $50 dollars cheaper. the other difference now is, the se530 comes with a modular cable, which is a shorter cable, and then you get to choose what length of extender you want to connect it to. ( comes iwtha 9 inch and a 36 inch) as to the e500 just has one long one coming from the earphones itself. other difference is, they improved the cables on the se530, now they do not crack and tear like the ones on the e500 did. Hope this had help. oh by the way, i use the se530 right now, got rid of my e500's. so get the se530 if you can.

I just bought the Shure e4c's from
Headroom and while purchasing them I discussed the new line with the sales person. She basically stated that the SE210 is similar to the e2c's and the SE310 is similar to the e3c's and so on...
She said that they had minor improvements over their predecessors but that they weren't really noticeable enough to outweigh their difference in price.
I paid $165 for the e4c's and the Shure SE420 (their new '07 counterpart) is currently listed at $349.99...
I can't say anything from personal experience though as I have only used the e4c's...

and the sales person was a bit wrong then. cuz the e2c's equal the se110, the e3c's equal the se210, the e4c's equal the se310 (Both have a tuned Bassported Driver) and the E5c equals the se420 ( both dual drivers). and no the e500 equals the se530. ( triple driver). All of the earphones in the Se line has been improved in someway to make it more comfortable to much better sounding. and to all of you saying. no the e500 is exactly the same as the se530. THEY ARE NOT THE SAME. read the post above to my explanation.
