This post won't be anything close to a full review, but let me just say, I love my Westone UM3x in-ears.
Even just working around the house today listening to my iPod, I absolutely love the fit and feel of these monitors, not to mention the sound. They isolate me from any noises, the wires tucks away tightly behind my ears and neck, and the cable is the perfect length to reach to my front pocket.
I wont even touch on their performance in live situations in this post, just wanted to say, I'm working around the house, and it barely feels like work with these Westones putting me in my own little world. :)
