“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 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 HY3 is a three-way, three-driver hybrid custom in-ear monitor from Sweden-based Cosmic Ears.

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.
The Noble 3 is a complete overhaul of Wizard’s original three-driver design, a process that involved lots of consultation with Knowles (leading balanced-armature driver manufacturer). With a ‘V’ shaped frequency response, the Noble 3 is characterized by a controlled, impactful, low end and far-reaching highs.
The Noble 4 is a neutral sounding product that should appeal to those who desire a flatter frequency response. An update from the Wizard’s four-driver design, the Noble 4 lacks the controversial dip in the high frequency region. The smooth, clean, sound makes for an ideal pairing with vocal, acoustic, and classical music.
The Noble 5 was inspired largely by the demand for a universal version of the Noble 8C (eight-driver acrylic CIEM). With deep, thick layered, bass and highs that never fatigue the ear, the Noble 5 strikes a balance between fun and articulate.
“ (copied and pasted from the thread) Intro Noble Audio is the new brain child of John Molton, who is known around these parts as the Wizard. Formerly of Heir Audio, his CIEM designs are usually his calling card. However, his initial universal-fit 4.Ai and 3.Ai, and 5 designs saw a...” --eke2k6
“I'm listening to these through a Schiit Modi DAC and Schiit Asgard 2 amplifier (totally overkill for these, but I was listening with DT990's before). I listen mostly to CDs which I own and rip securely, in addition to Spotify's subscription-quality streaming. I'm not very experienced with reviewing headphones, but I will say this: These are my first CIEMs, and with this I purchase...” --Baldoak
