both have same hardware, runs Toshiba stack (you may need time to get used to)
in the real world test, it has amazing RF/RX
I put my laptop inside the cafe, plug it onto USB hub, and it stands uprignt
with itech S38 bt headphones in stereo mode, I can get signal up to 25 meters (absolutely maximum)
with HP RX3715, connect to host through async, I can get signal 30 meter+
only product is better is billionton UBT-B1, but there're too many counterfeit (used IVT junk), that I wouldn't recommend
