“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

“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
“If the A50s gave you the option to customize the presets, I imagine that they would be great for FPS gaming. However, they do not and even the preset with the least low end has too much to hear any of the subtler sounds (e.g., footsteps). I use them with a PS4 and have tried every possible combination of settings to no avail. There are far less expensive options on the market that offer more...” --Hoopdy
“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 sound quality is a lot better than they make it seem, the marketing shows it being used with PSPs and phones, but they are capable of handling more than angry birds. I use these for PC gaming and music. The sound on these almost compare to my Sony MDR EX700LPs, but with a better soundstage and less bass extension. I actually prefer these to the A40s, they...” --jimmy895
