I haven't used the Shure's so can't comment on them. However I can say the last thing the x10's are is flat. Bass is strong and full without overpowering the mids and highs. Highs sparkle and there is great soundstage for such a tiny set of buds. They're a great option and an awful lot cheaper than the 425's.
