I wanted to give a short review on my new Alien Ears CFR3 s that I have used for the last 3 weeks and absolutely love them. Them fit my my ears perfectly and sound awesome. With great tone ,separation and clearity and they look good as well(upgrades wood facings) I couldn't be happier with the fit and great tone. One other item I'd like to mention is the fact that I sent my UE's in for the trade in program and found out they don't do ant customized IEM trade ins, I was disappointed but what he did do was fix them for me at a very minimal cost for a back up. So I consider that great customer service.
