Wow, she loves them. After seeing me buy the the Westone 4s a few months back, she has always wanted a pair of IEMs where the wires go over her ears, as she thinks they look so cool. It was a choice of The Westone 1s or the UM1s, I opted for the Um1s cause it was cheaper....hehe....no seriously because of the clear casing and it was slightly smaller in size. I tried listening to them and they were not bad sounding at all. A great improvement on the generic earbud phones. She was using US$50 Sony ones. Her sister, 11 years old, have the Lady Ga Ga Beats? which are more expensive than the UM1s and the Um1s blows them away. All very happy....have to keeps the girls happy!!!
