“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've been out of the loop for a while when it comes to budget IEMs. Back in the day, the low priced options were simply not very good. I remember paying $40 for the V-MODA Bass Freq as a workout IEM because I liked the massive impact, though it was obviously not an "all purpose" type IEM.

I bought these primarily to use at the gym with an ancient RCA mp3 player that only has 512mb, because expensive gear and sweat don't mix IMO. These setups fill completely different roles, so I obviously don't expect them to compare, but I think it's important to...” --manbear
