Yes, the UE900 tips. And I've been A/Bing. I still think the Ear Speakers have a bit more clarity overall than the AS-2, but both are close in fullness of sound. I think the mids are more forward in the Ear Speakers, but the vocals may bit more forward in the AS-2. I think the AS-2 is a bit darker sounding, but I'm nitpicking. Both are great IEMs. I think the Ear Speaker is a bit more refined, but I'm glad I own both. Clearly top tiers on another level.
Just got a used pair in today.
I'm impressed as well. Huge sound stage, really do rival the ASG2's.
Eric, you wrote them up in one of the other threads, perhaps the Discovery thread, saw them on ebay used for a lot less than list, and jumped on them based on your recommendation. Glad you mentioned them, I'm quite impressed.
Cable is rather big for an earphone, not sure how I feel about that. Fit came with some medium Ortofon eartips.
