For the cost they're pretty good sounding cans. The range on them before they start getting iffy is quite bad though if you're in a congested area. I have to keep my phone in my right pant pocket when I'm downtown to have any sort of a stable connection.
Yet another reason to avoid moving to "the big city", although I suppose that would be problematic when travelling. On the plus side, if a person is going to be that close to the source, they can always use the wired connection (which I'm assuming comes with a bigger power draw penalty). I was actually impressed with the ability to move around through the house with them on... seemed to start getting the occasional connection "burp" at around 30'.
I've been hmmming and hawing over picking up a set of Bluetooth IEMs but was holding off based on a concern that the audio quality wouldn't be on par with a mid-level wired set. These were reasonably well reviewed, and the price was right.
Their documentation absolutely bites though......
