“ I bought these to replace my beloved A-Jays four. I needed something with the integrated in-line ipod/iphone controls, but with a bit better audio-quality, and some that may not pop out as easily as the JAYS. These have a "secure loop" system which provides an adjustable cable loop that tucks into your upper ear, helping to keep the buds in place. I personally found...” --Dneale
“This is a review of Bowers & Wilkins B&W C5 Series 2 (new 2014 version) in-ear premium headphones with in-line remote. http://www.bowers-wilkins.com/Headphones/Headphones/Headphones/C5-Series-2.html Often after reviewing full size headphones people ask me if I can recommend something with a similar sound signature in a scaled down in-ear design.

“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

“ Using TheHeadphoneList's Review Format Below Accessories - 3/5 You get a semi-hard case with a felt-like exterior that zips up and 3 different sized tips to help fit your ears. Silicone style tips. I was actually able to get a great seal with the stock tips which was a shock to me, as my two ear canals are typically different enough to warrant different sizes. Most...” --RubxQub
“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
“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
