“Copied from: http://www.head-fi.org/t/686039/cosmic-ears-ba4f-review I'm finding it hard to rate these, for the price I would give them 5 stars on every department. But I'd rather rate them, referenced with the idea of what the very best cIEM could be. The BA4f with the Ice Blue color Short History Before I started my journey into the cIEM...” --Marleybob217
“First of all I'd like to say the customs and the cable are both insane, the customs look incredible and the linum cable and connector beat the hell out of any other CIEM I've seen around. Cosmic Ears list this as a jack of all trades monitor which I do agree with. I'm coming from a 4BA model to this 2BA and I've been pleasantly surprised by the sound. I haven't had these a week yet so...” --daftpolecat

“ I bought these as a replacement for the crap apple headphones. I immediately appreciated the nice, loud and solid sound, and how they felt like they belonged in my ears. The concave shape of the casing just feels right.
