so with other words, nothing changes internally which will change the sound like what Jude mentioned...
Fit can certainly affect sound, but I don't think that's all that's at play. Both seem to fit me equally well (though inspection of the two does show that they're not exactly alike in every way, with regard to every nuance of its shape/form).
Anyway, here's a Westone press release about the new stuff I came across when trying to see if I could find any other information about any difference(s):

I contacted Westone to see if they were planning to offer an iPhone remote cable for the ES5 now that they've announced ones for the ES50, and this is the response I got:
"Thank you for your email. We will be offering an upgrade option for your ES5 shortly. You will be able to send it in and have the new socket,cable, and faceplate put on. However, at this point in time, we do not have pricing. I am still waiting on this. But upgrading will be an option. Please let me know if you have any questions. Have a great day."
Pretty awesome! Hopefully it won't be too expensive
