I've had the EE EVO for a couple of days now, they are like nothing I've heard in an IEM, or over-ears, except the Abyss 1266. Every other IEM, that I've heard, images like mini-monitor speakers, the EVO (and Abyss) image like large, panel speakers (think Soundlab). It's quite amazing, though it takes a little effort to get there, you need the largest, soft silicone tips you can fit. Foams, Peels, even the Crystal are suboptimal. Once you get that seal, and maximum surface exposure for Weapon X to do it's a thing, these are the best IEMs I've heard (I haven't heard the Tralli, Erky, or X).
On another note, I have a bit of hearing damage in my left ear from exposure to loud noise, the full range of bone conduction fills in the missing audio information (confirmed by Jack). I'm still “learning” the EVO, but from what I've heard, and felt, these are a unique offering that stands out in a crowded field.
