“This is in my humble oppinion the very best bang for your buck custom in ear monitor on the whole market. For 250 british pounds you get a very nice piece of equipment, from very nice people too! The guys at cosmic ears care about their stuff being done properly and on time, they checked everything to be correct, from my ear canal impressions to colour, logos, letters, etc. They also come with...” --ardacer
“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 remember getting my first iPod in 2007, the 3rd generation nano. The earbuds that came with it stopped working when I left them in my pocket and washed them, so I ran out to Best Buy and picked up these since they were on sale. I actually still have them in almost the same condition, but nowadays I just use them as my occasional backups for my daily commute to school. But enough of that...” --theBjrd
“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
“ I'll just go and rewrite this... Anyways, these would be my 2 year old IEMs that I still haven't managed to break. Pretty impressive considering how many times I've shoved them into jeans pockets. Anyways, onto the sound. They're a very aggressive sounding IEM, with an apparent spike in the mids and a slight spike in the bass. This makes it a fun listen though, without...” --Byakushiki
“The HY3 is a three-way, three-driver hybrid custom in-ear monitor from Sweden-based Cosmic Ears. It utilizes a dynamic driver for the bass and twin balanced armature drivers for the midrange and treble, which used to be a very rare configuration, although hybrids have increased in popularity over the past year. The bass unit looks to be around 8mm in diameter and has its own sound bore. The two...” --blueangel2323
