“ Do not buy these. They sound good, true. But with the price they ask? NO! Better sounding alternatives are available at over hakf the price of this! Sound quality is good, but the sound it gives for the prices is just crap. I expect something better for $60 IEM's. ” --Ezio
“ Sooooo...after 2 years of faithful service, my trusty westone um1s have finally played their last song and died (the left earpiece has no sound coming out of it) so i figured it was time to get a new pair. I've since ordered the eytomic hf5, but until they got here, i needed another pair because apple earbuds hurt my ears. As such, i got another set of these guys, which also happen to be...” --fluffyberry
“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 HY2 combines a dynamic driver for lows and a balanced armature for the mids and highs. This dynamic driver also delivers an increased soundstage.

“ This IEM is definitely the best bang for the buck! Basshead person should purchase it without a doubt. Even it's higher brother, Philips SHE9800 didn't able to match the sound quality of this IEM! :D It produced very deep punching bass and high definition clarity on mid and treble. It feels like you have your own built in sub-woofer inside this IEM! Comfort to use in a long run,...” --chrone

“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

“ I have to say, as introduction: I'm not an audiophile, just an "enhanced" user with more than 20 years of analogic and digital listen. I use mainly portable devices, some Fii amplifier, and I listen pop-rock-ethnic (50%) classic (20%) and jazz (30%) mainly lossless. And finally my english, it's not "mother tongue style", sorry for this. This product (on amazon, 60 euros) has an...” --pignolo
