I can officially say it, this ones and the acoustune hs1670 are the best Iems I’ve ever listened to, i really cannot get more surprised, i never heard the andromeda’s but if i do so, they really need to pull some sort of magic trick, the aten soundstage beats the living crap out of many of my open back headphones, and the amount of possibilities is amazing, I’m not shy to eq a bit when needed, purple set (tip and bore) sounds amazing with a bit of eq in the mids and highs, It’s like having the monoliths on (fuzzor mod, leaner back pads, sheep skin pads) I’m so glad I got this guys, detail retrieval in this set is amazing as well
