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

I got this another unit (both pictured) to compare. I really like the aesthetics of the smaller one better but this one provided volume control and the signal flow was still very clean with no added noise and no volume loss (which sometimes when you add a volume controller you lose some headroom on the max side of the dial- on this unit you do not- 100% volume is truly 100%, at least from a human hearing perspective). The quality of the sound is great, just like a clean pass-through. The build quality is nice but the "feel" of it is only OK. The aesthetics could be better and this feels more like a folded sheetmetal case vs the other unit is a solid machined piece of aluminum with a much more premium feel and weight. If you don't need volume control and want something more premium, I'd go with the other unit. But if volume control is important, this unit is excellent. Easy to use and highly functional. The switching is clean with no static or noise between changing sources.

Easy to hook up and works as described. I often switch from speakers to headphones, and this product was really helpful. One button. Easy.

works as described. It does have a audible "pop" when switching between sources

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.

Well guess you can't expect much for this price range. One of the input/ output jacks fell off the circuit board. Inspection found poor solder joints/ materials. Was going to install a new one but unable to locate suitable part or wiring diagram. Only used this occasionally and would had though it would have been manufactured better. Case is extremely solid however electronic components are soldered poorly. Unit was installed connecting headphone and speaker to a radio output. Items were left plugged in and was only occasionally used over the period os a year (No repeated plugging or unplugging) I feel that if I had been repeatedly plugging and unpligging jack it would not have lasted a week.Some quality control would go a long ways.

I am using this audio switch/volume control to attach either a Bluetooth receiver or audio from a monitor headphone jack to an amp and speakers. The unit works perfectly with no loss of audio quality. I am using high quality audio cabling and I am not experiencing any audio hum, buzzing or distortion as mentioned in some of the ratings. Quality of this unit is excellent for my application.

I used this selector on a pair of headphones to listen to a Zoom meeting mix. I can listen to the mix at the mixer before going into Zoom and then I have an iPad hooked up as a Zoom end user for the other input. I can make adjustments on the mixer and switch back and forth. Note that Zoom also does noise reduction and processing in its software so I found that I needed to boost the level on the mixer to compensate for the Zoom processing. There are also adjustments that can be made within Zoom. So getting to hear the mix at different points is very helpful in producing a good Zoom meeting mix.

The product is fantastic. It works well as describe. No stress in setting it up. Perfect and awesome item.
