Naturalness is perhaps the most apparent strong point of the IE800, especially in the mids. I've been using these phones for more than a month now, and think their mids are simply outstanding: natural, realistic, ultra-smooth and hyper-detailed at the same time. I can't think of any IEMs I've heard (including the UERM and JH13) that would top these sublime mids.
However, where there's light, there's also shadow. And in case of the IE800, the latter cannot be overlooked. Hope I'll find the time to wrap up my thoughts this weekend and post a short review, or at least some final conclusions.
Hmm. You make them sound quite dark. And I do like dark! Your write ups are always good james so I look forward to it :3
