If you are going to work with RaspBerry it's not 100% compatible. **Q: HH, can I ask what brands you purchased that were good? Thank you.** A: Like I said, I have been unable to find another usb audio device that supports stereo microphone inputs. I have never had any issue with any usb audio device except this one, in terms of the hardware being such low quality. There's a lot of usb dacs that are not too expensive. Depends on what you need. **Q: What is the difference between c1-1021450-1 model usb-sa-1 and usb-ma p-c1-1024200-1? should i prefer one over the other for use with dragon** A: The c1-1021450-1 usb-sa-1 (which I bought) has a short cable between the USB plug, and the part of the device with the audio mic/speaker jacks. I believe this design puts less pressure on the laptop's USB jack, and lets the audio cables go off in a different direction more easily. The other model, as far as I can tell, does not have that cable or that flexibility. **Q: Is this compatible with Windows 10?** A: It works, but it stops after a bit and you need to unplug it and plug it back in, making it not reliable. I purchased this one and I havent had any issues with windows 10 and its cheaper.
