    Works great. I changed from analog audio in/out for mic and speaker. Windows got confused on which USB connections was for mic when the audio out USB was added. Finding the right setup fixed the problem.

    I use this USB-to-3.5mm headphone adapter to plug my headphones into the USB ports in my monitor placed on top of my desk. The headphone cables are too short to reach my computer on the floor and still allow me enough length to move about comfortably. My headphones worked right away without any kind of setup needed. I am running Windows 10 OS. That sound quality for the speakers and microphone in my headphones appears to be equivalent whether I am using this adapter or plugged in directly to the computers 3.5 audio jack. The blue anodized aluminum connectors are a nice finish. The 3.5 mm connector has a logo indicating it can be used for both audio in (microphone) or out (headphones, etc). I would definitely buy this adapter again.

    This cable allowed me to connect audio through my usb-c hub so that I have one thing to plug in when I sit down with my laptop. I also now have a free audio input on my Macbook so that I can have a headset mic and separate speaker hooked up. I like to do this sometimes because the audio on my speakers is amazing, and the headset is mediocre. The audio quality of the mic through this adapter is great. I had to turn up the gain in my computers audio input settings to get the volume I wanted for my headset mic, but other than that it seems about the same audio quality as my computers input. I really like the build quality. The cable is nicely flexible. The metal audio input end feels great, and the USB end has a solid feel to it. Just feels like a premium product. Overall, it did what I wanted, I didnt have to do any setup, and it feels like it will last a long time!

    I used this cable to connect audio from my microphone to my computer. It works great and the sound quality was not downgraded. I like the aluminum connections and quality cable so there is not cracking or breaking issues due to constant flexing.

    I have a work laptop with no sound card. This gadget allows me to run speakers or headphones. Cheap workaround and does the job.

    I bought this product to connect my wireless Rode Go mic and transmitter to my laptop. The sound quality on my HP laptop was not sufficient [not loud or clear enough] to teach online classes. It has been working perfectly since covid 19 forced so many of us to adapt. It has been reliable and trouble-free since day one.

    Just plug this adapter into a USB hub, which is connected to what ever device doesnt have a 3.5mm jack, and you have a port for all that sound equipment that is still perfectly good.

    I have a pair of heaphones that has the 3.5mm on the right side (the side with the mouse), and USB on the left side. This helped me plug my headphones on the left side of the laptop (so the cord would not interfere with my hand using the mouse. For Zoom calls, this was good.

    Used this on my asus laptop because headphone jack that came with it stop working. It was an easy fix to plug this into a USB port so I could listen to music again.
