My soundmagic e10 are pretty much on their last legs now and I'm looking to replace them. I've toyed with the idea of keeping a wired set, and actually tried the soundmagic e50 (massively disappointed) and have now decided that wireless is the right way to go for me. So... Looking for a recommendation on some decent sounding Bluetooth IEM. Budget is roughly 150, would like lower but would also go slightly higher if they are worth it. In terms of sound preference, I'd like something with a bit of character (so not a straight reference type set) but I don't want something that is rediculously bassy. Previously I'd tried the jaybird x3 and was massively disappointed in the lack of subtlety if that helps. All recent reviews seem to point to the sennheiser hd1 free. They are a hit over my price range, but if they came highly recommended I could stretch to them. Any thoughts?
