I've been using my newly acquired Soundmagic E10BT's for a week or so now and can say they're excellent (as were the original E10's). The only downsides are they no longer come with the Comply tips and that the battery (which is halfway along the linking cable) can be a bit awkward. Although saying that I just clip it into the neck of my t-shirt (around the back) and it lasts for 12hrs on one charge!
