I received my ATR order today from Gearbest. Initial impressions:
Mine came with the foam tips installed. One tip was kinda smooshed from the way it was packaged, and they did not feel comfortable. I swapped them out for Spinfits and like that much better. The ATRs sound good straight out of my iPhone 6S with Tidal, but even better through the Mojo (no surprise there). The highs sound a bit sharp to me, and the shape is weird....... the long canals and end weighting make it difficult to keep them in at the optimal angle. I got a tragus piercing in one ear before I started this IEM odyssey, so fit is always a problem for me. The Spinfits help with that.
These are very detailed, and the bass kicks yet is not distorted. I think these flatter female vocals vs. males, as the bass bleeds into the mids a bit.
That being said, these are the best under $5 IEMs I have. Actually, they are the only under $5 IEMs I have, as the Monks are $5 and are earbuds. If they could be put in a casing that I could fall asleep with (ear on pillow) I'd pay at least 20x more. These may replace the Rock Zircons as my work IEMs. These sound much better than the price would imply!
