There is no such thing as a (unique) sound like "live electronic music", since electronic instruments require amplification and loudspeakers.
If you mean what you hear in a concert, it totally depends on the venue, it's equipment and electronics and whatever the sound engineers and/or the artist(s) wanted to do. Add to this your placement on the venue and the raw SPL which will affect your perception of the sound. I've never been to two concerts that sounded the same.
I do realise what you mean, though, and I do agree that the HD215 sounds like the sound at a crappy electronic music concert, with ear-raping SPL and treble.
By live electronic music I really meant live electronic music.
Have you ever been to nay of these:
I believe these are far from "crappy", but again my opinion only.
