Are Klipsch Image S4s better than Shure E2Cs?

I'd like to upgrade my earbud 'phones.

Currently have Shure E2Cs; contemplating Klipsch Image S4s. But, obviously, retailers don't offer demos for earbuds.

Should I expect the Klipschs' tech to offer significantly improved sound compared to the Shures' or is it merely a case of 'they've similar sound quality, so whatever floats your...'?

Thanks.
