Anyway - I can give you a rough comparison against ES7 as I have owned both of them. In few words - similar, but better in every department. If you have/like ES7's, you can't go wrong with ES10's. You may also want to try ESW9, IMO not a big step down (if any at all), but woodies are much more comfy (mainly due to the leather earpads).
