Hello! Just got my pair today. Posting some pics and first impressions.
* I quite like the stock tips. The mediums, which came installed, fit perfectly. The material used actually reminds me A LOT of the tips on my J+- Wooden Earbuds (they were 5 CAD...take that as you will). From the sounds of it, I am in the minority when it comes to liking these tips.
* The build quality is great. Could not find any issues with fit/finish on the housings, and the cable feels awesome. Nothing like any of my other headphones. I quite like it. Microphonics are a bit invasive at low volumes though. Strain relief at the plug/jack seems a little stubby...
* Out of the box they sound nice, but less bass than I was expecting; sound about the same as my FXT90. The mids are a bit less forward than I like, but still sound crisp and clear. Highs are less in-your-face and more smooth than those on the FXT90s (this is a definite plus).
* If they sound this good out of the box, I can't wait to see what some subjective 'burn-in' will do.
**Quick test done with my Nexus S, eq'd for the FTX90.**
