Over the past week or so, I've been looking for headphones to replace my recently broken Thinksound Rains. At the moment, the VSonic GR06 IEMs and the HeadDirect RE0 IEMs are at the top of my list. However, I don't really know if either of these are the best choice. My limitations are a $100 budget (can squeeze a little more in for shipping) and they have to be small, preferably not open-back. I'd rather not distract my co-workers or people commuting on the train with me. Any help would be appreciated. Thanks in advance.
