“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
“When I first started looking for a pair of CIEMs, I was determined to find the best one in the $1000 region that would serve me equally well for everyday listening as well as stage use (I play in a band) and after quite a bit of deliberation, settled on these, and man was it a good call. What follows is just a few of my thoughts on this excellent piece of audio goodness. Gear ...” --fluffyberry
The Pure model is the fantastic entry model to our range of customs yet it still has the benefits of custom in ear monitor. The Pure fits perfectly to your ears, these high-quality headphones deliver a rich sound that off-the-shelf earbuds simply cannot match.
“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

The Flex model is designed to allow you to configure your earphones enabling you to build the perfect listening companion.
“ Fit and finish The PS200 fits well in my ear canals, although the body is on the large side. Because of this, they constantly push against my antitragus, making it sore after a while. However, I doubt this will happen to other users. Isolation is quite good; they isolate about as well as my ER6s, despite using single-flange tips. However, the tips are quite thick, and don't squish down quite...” --12345142
“ First, I want to thank Phiaton for the review sample. As a headphone brand, Phiaton is relatively new to the scene. But as a company, it has a rather long history. Phiaton was setup by Cresyn Korea in 2008 as an initiative to launch its own high end headphone line. Up to that point, Cresyn has been very successful in the headphone OEM/ODM business all over the world, yet not quite known...” --ClieOS
“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
“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
