## Questions & Answers

**Q: Is it compatible with Window 11?**
A: Yes, It's compatible with W11. 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent product
*by V***. on August 21, 2025*

works perfectly

### ⭐⭐⭐⭐⭐ Quality sound
*by K***Y on August 2, 2025*

Great sound card. I've been using these Andreas for almost 20 years in court reporting. Great quality.

### ⭐⭐⭐⭐⭐ Best of several brands tried
*by K***O on February 7, 2016*

I use mine with a lavaliere microphone that has a 3.5mm mini-plug, to record training videos onto my laptop for work. I have tried similar devices including those by Sabrent (noisiest, and does not work at all on some laptops), Turtle Beach (worked on my older laptops, useless on new ones), Audio-Technica (an improvement, but still noisy) and Plantronics (OK). This one is the best, because of the noise reduction when recording -- there's still some hiss, but so little that it's easily removed in Audacity or just ignored. My son also has one, which he uses as a headphone amplifier and it also works better with headphones than any similar device we have tried. So, between us we have found this the best choice for both sound in, and sound out, where USB is the best available interface but your listening or recording device has a standard mini-plug. Well worth the few extra dollars.
