4-Port Bidirectional 3.5mm Audio Switch with Volume Control

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.

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.

Fixes the issue i was having of multiple computers/devices and one speaker system I want sound to be processed through. I went with a knob switch instead of those electronic buttons because this feels like it would be better quality and less likely to fail. I plugged everything in and got a humming sound (like some other people pointed out). It was resolved by moving the volume knob all the way up. This means I will control volume directly from my devices, that's not a problem for me as that is what I was planning on doing. Kind of sucks that I do not get another layer of volume control. I am sure some A/V guy can describe/point out why this is happening and how to fix it. But I honestly don't care as it fits the need I wanted this switch for. I'd get it again (But i won't because my need is now met)

This was perfect for what I needed unfortunately it only lasted about a year, then the connections went... It's as if the solder points began separating... If I jiggle the input cable (any of them, not just the active one) it comes and goes.... even replaced all the cables to rule that out.and issue remains. Time to replace it with a better unit...

The first thing I noticed was the weight, it is very solidly built. Compared to my previous purchase of a similar audio switch this one far superior. It works just as it should and I am very pleased with it. Highly recommended.

Works great for me to switch one set of speakers between different inputs. The sound is great - I didn't get any reduction in volume or any new interference.

There were a number of one-star reviews for this item, but I found a solution that works perfectly for my situation. I wanted to be able to switch my earbuds between four computers, but some reviews said the volume control on the LINKFOR didn't increase volume sufficiently. Others said the sound quality was not good because of a faulty volume control on the LINKFOR. I paired it with an LVY-015 Portable Headphone Amplifier, and the result is perfect. The LINKFOR allows connections to four audio sources, and the LVY gives you USB powered audio gain. I just plugged the LINKFOR output into the LVY input, and my earbuds to the LVY output. I now have all the volume I want by adjusting the LVY's volume with no need to touch the LINKFOR volume. I choose the audio input I want, adjust the volume, et voila!

The switch works fine for headphones, but when I plugged in my speakers (Creative Pebble Pro, powered by a wall outlet) they sounded hollow and tinny. It completely removed all the bass and made them sound like low quality laptop speakers. (If I plug the speakers directly into the computer, they sound fine.) Also, the volume knob doesn't work as expected. Instead of a gradual increase/decrease while turning the knob, it only has about three or four actual levels that change suddenly when the knob hits certain points on the dial. It's functional, but it's not what the design of the volume control suggests you're getting. The metal case seems well constructed and the rubber feet help keep it from moving around too much if it gets bumped. There's no noticeable buzz or hum as others have reported. Not sure it was really worth $25.

Does the job perfectly.

Très bien conçu, vous branchez et cela fonctionne. C'est exactement ce que je recherchais. Le boitier a l'air solide et tient bien en place.

Dźwięk, który dochodzi, jest bardzo zniekształcony i cichy. Jeśli nawet dotkniesz pokrętła, dźwięk zostanie wyłączony i doda szum.

Très facile à faire fonctionner

本体が小さく簡素な作りで気に入っています。ただ据え置きを考えていた自分には入出力端子穴は本体の同じ面にほしかった。ついでにボリュームコントロールの代わりに出力が２系統あれば最高。
