“I really like this earphone because it gives you wonderful sound quality at a reasonable cost. When I started listening to all the songs on my laptop with this earphone and also all of the smooth jazz, it was as if the whole world was cut off because of the noise cancellation. I use it on the airplane and I couldnt hear the tons of babies that were on the plane . I tried it with three...” --SandyMan
“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

“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
“These buds came from amazon I was simply looking for something more suited to the bass head genre of music that really packed a punch. True these do pack a punch but to be very honest with you all they only pack a punch. The bass is actually extremely poor, there is a difference between punch and tight punch. The bass in these gives a punch that makes your ears rumble but the actual detail and...” --Hawkinssa
“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
“Hello fellow Head-fiers!. This is my first review in Head-fi, but before I begin, I'd like to give a brief introduction about me. I'm an average individual who loves listening to almost wide range of music genres from classic to rock, except current pop, rap, and hip-hop, but I mainly listen to songs as long as they sound good! I primarily listen to metal and rock; but recently, I've gotten...” --Gandasaputra
