“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
“I have the Harmony 8 (H8) for a while and I thought they are really good, good enough to make me write a review about them. I had shared my initial impressions in the Custom Art thread here but they evolved and changed, mostly in positive way. It is a part of the flagship duo Piotr has now. Harmony 8 is the one I am reviewing here but Harmony 8 Pro version also reached a quite success in...” --AmberOzL
“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

“I have Music One for a while now, I already wrote some impressions in the Custom Art thread in here. So I decided to combine them and do a proper review. It is a little gem that punches way above its price point, so definitely deserves a review in my view. Starting with the design. Single BA per side, silicone earpieces, permanent or optional detachable cable (with a little extra...” --AmberOzL
“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
