“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
“ The JH13 Pro was my first purchase of high-end personal audio equipment so it's difficult for me to provide a fair comparison (prior to purchasing them, I was listening to iPhone earbuds), but I can safely say that I couldn't possibly be happier with my purchase. The process of getting the impressions made was painless (albeit a bit expensive in the San Francisco Bay Area), and...” --WKHarmon
The HY2 combines a dynamic driver for lows and a balanced armature for the mids and highs. This dynamic driver also delivers an increased soundstage. The HY2 is a great sounding monitor for those looking for something a little different by combing the 2 driver technologies. Twin hybrid – 1 for lows, 1 for mids and highs Full sized medical grade hard acrylic shell Various...
“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 orederd a pair of JH 16Pro IEMs in May. It is now June 15th. Since ordering the first pair, I have returned at my cost of $21.15 each time, the IEMs three times. Each time, Caleb Ellis, who manages the department that makes the IEMs, said he could not explain what had happened. The left IEM of the first pair fitted perfectly with the impressions I paid an ...” --rollinoswald
“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 bought these to upgrade from my UE triple fi 10 pro's. I LOVED the Triple fi's, but wanted to go to customs for greater bass response and isolation on stage. (i'm a bass player).
