Thanks for suggestion :) They were on my radar although I have been looking into their successor IE800 as well. How are the highs on those in comparison to HE-400? I am slightly hesitant on those because I heard the trebles are are on the laid back side whereas my preference are the in your face detailed like the HE-400s.
I would recommend the GR07-BE (naturally as I own it ). There are a lot of options out there that would be well suited, and I've heard good things about Marleybob217's recommendation with the BA200 - it's one IEM I've considered and would like to try sometime. It is a balanced armature design though, so I'm personally not sure how the bass presentation would compare between a dynamic IEM or a planar bass presentation. I can say the low end response of the BE is pretty spectacular IMO and it's quite fun sounding overall.
Haven't thought of that one. I'll have a look :) Cheers for the suggestion!
Another one that was on my list. How are they in general? Not much info of these on the net and would like to hear some opinion from a HE-400 owner! :D
