I beg to differ on two occassions: Soundstage Depth and Coherence.I will continue with my review next weekend and hopefully be done then.
Right now I think it is an iem that I can recommend to bassheads. Not so much for everyone else. Since even I find the sub-bass (rumble) to be a too much...
Slightly below average technicalities for the price it is at, except the soundstage which I do find to be holographic due to big width and depth.
I think the FH3 is a safer rec though, slightly better technicalities (except soundstage) and a much cleaner sound overall that is also less fatiguing (that rumble and the super heavy weight are pretty big dealbreaker for comfort, as I can only use it for an hour). Although the coherency and timbre are very impressive on the OH10, very Sony-like actually.
Soundstage Depth was definitely less than what I am used to. Even Penon Fan had more depth. But less width.
Highs were a bit too sharp, grainy, and out of balance w.r.t rest of the spectrum.
