LiNKFOR 4 Port 3.5mm Stereo Audio Switch, 4 Way Stereo Audio Selector, 4 Input 1 Output / 1 Input 4 Output Audio Splitter with Volume Control and 4 Channel Switch Knob

Works as expected with no connection or sound quality issues. A simple button press to switch between devices and a solid smooth feeling volume knob.

If you have multiple computers and multiple monitors with separate studio speakers, this is a good way to switch audio between your computers using one set of speakers. An actual KVM switch that can switch multiple computers and monitors between a single keyboard and mouse with audio switching as well can get very pricey, whereas if you for-go audio switching the price drops and it opens up more options, such as Display Port with HDMI, versus just one or the other.Now there are no active electronics inside this well built sturdy box. So it can’t be used to increase the volume over what is being sent through it. So keep that in mind and set your computer volumes and speaker volume accordingly.Being a passive device it does not degrade the sound quality at all.I can’t speak to the longevity of this device but with some care I would think it would hold up well. At least if it does go bad for some reason it would be fairly inexpensive to replace vs having the audio go out on an expensive KVM. The only caveat is that to switch between your computers you have two operations. This audio system and your KVM switch.

My new KVM switch did not have ports for sharing my speakers between two computers, so I had to look for a dedicated audio switch. This one is doing the job. So far, I've had no problem switching from one device to the other. I keep it beside the KVM, so when I switch one, I also switch the other. The price was very affordable with one exception.The 3.5mm cable that comes with the unit is too short. I had to buy three new, longer cables which increased the cost of ownership. That is why I downgraded this review to four stars. If you are not bothered by that, then consider the product to be five stars for price and performance. I've only had it a few months, so I can't say what the long-term quality will be. Fingers crossed.One of the most important features of an audio-sharing device is sound quality. There is no hiss or static. The tone is clear and good, though I perceive there is some signal loss (volume). It isn't enough to send it back.When I got the longer cables, it was easy to set up. Since both computers I use have 3.5mm ports, connectivity was no issue. Everything works.Pretty good product and I recommend it with the above caveats in mind.

With only one audio out on my PC, this allows my powered PC speakers and my headphones to be hooked up at the same time, and the ability to switch between to two. Can be used in reverse with 1 input to 2 switchable outputs. In my case the volume control and mute switch are not used, but if you need it, it's there. Nice little switch. Well made.

Use this for a classroom setup where I need to route audio from a projector, and audio from a bluetooth receiver to the same set of speakers. This lets me select the input quickly and easily, versus plugging and unplugging cables constantly to accomplish the same goal. Fully passive, so it does not require batteries or other electricity input. Awesome and less to fail that way.

Exactly what I needed and wanted. Thanks

Worked for about 3 months, now it has a high pitch squeal about half of the time. Do NOT BUY!!!! total garbage. I tried different cables to makes sure that wasn't the problem and it wasn't it is the stupid box creates some kind of feedback loop.

As stated in ad a very good buy for the price.
