“note: I am a noob and very inexperienced when it comes to audio. The following is not really a review but an extended comment... --- As soon as I read Shigzeo's review of these, I knew these might just be the phones for me. I was a bit worried about the fit since I have alien ears, and no IEM has ever been completely comfortable for me. Although it's not too comfortable wearing them like you're...” --rymd
“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

“ IEM’s are known to have two driver types, balanced armature, and dynamic drivers. Recently, IEM’s like the Grado GR10 and the Ortofon series of earphones changed the IEM industry with moving armature drivers, which copy the movement of a regular dynamic driver. But, what if someone were to make a new IEM, one so fully loaded that it includes dual dynamic drivers to deliver a whole new type of...” --Austin Morrow
“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

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

Twin hybrid – 1 for lows, 1 for mids and highs Full sized medical grade hard acrylic shell Various...
