Works exactly as it should
Ordered a much needed USB headphone port and the delivery was very early. It works exactly as it should and the sound quality is excellent.

improved sound, very happy
My computer sound always had a too low volume and, unfortunately, the jack for earbuds is faulty, so I could never use them. This USB gadget solved that problem and the volume I can now get with my earbuds far exceeds the regular volume of the PC.

Worked as designed and expected

The product is Ok if you want to just listen to the audio. If you want to record something from microphone, the audio input is very poor.

I bought this because both of my sound 3.5 jacks no longer work on my pc. I plugged it in a USB Port and works really well for my speakers I like it!

had to arrange to return this as faulty. only one of the earphones is working and the mic is not working. It looks like this stuff has a connection issue. Poorly made.
