The iOS app is buggy, the noise floor is high... I wouldn't even call this prosumer level at this point. Perhaps I'm expecting too much from a $230 device? (although I preordered at 50% off)
The idea of wirelessly capturing decent binaural audio to my iPhone is alluring though. Perhaps I'll just save up for the d-Vice from DPA, since I already own a lovely pair of 4060's.
