CubiluxBidirectional 3.5mm Audio Switcher (1-in to 4-Out / 4-in to 1-Out), Stereo 1/8” Aux Selector Box for Speaker Headphones/Earphones, Audio Switch for Laptop Computer Smartphone Tablet

The materials are quality, it has a nice rubber layer on the bottom to keep it from sliding around. I used it to allow me to plug in several morse code keys, and select among them easily. I could not use other products to do so, as they had a volumn control that dropped the low voltage. This worked perfectly, and did not effect the sound at all or add any noise to the line. It's a very nice size. Like some others, I would prefer if the inputs were on the back, and the output line was on an end, but maybe in the future.

I noticed that channels 1 & 2 are related and channels 3 & 4 are related.I had a noise source on channel 1 and ended up detecting it in only channel 2. I then switched it around and the problem moved. Also if the unit is near any noisy electronics, it pick it up.Switches as intended, works and for how cheap and small it is, its not bad for the money.

Pros: small, well built, easy to use, aligns perfectly with most dual-port 3.5mm headphone jacks.Cons: if you plan on using this with a computer and externally powered devices (aka plugged into 110vAC power) and you do not have a ground isolator, you will need an inline ground-loop isolator or you'll continuously hear "computer noises" through your system. this is not a fault of the device itself as you'd have this problem no matter what passive splitter/mixer/selector you use due to equipment grounding issues that are very common with computers and 3.5mm analog devices.overall, I love the little device. I use it as an input selector for the outputs on my monitors to my on-board sound card. plugs directly into the triple monitor mount with a male-to-male 3.5mm adapter and sit flush on my desk. I'd guess mine is a less common use, but it certainly does the job quite nicely.

I can't even use this with 2 devices plugged in! There is so much interference from the 2nd device that the sound is terrible. With 3 devices it's unusably bad. With 4 devices it's a f---ing joke. They are lying to their customers. There is not "full isolation" between the circuits, if there is then it's not working. There should be no difference in my sound quality if I plug a second or third or fourth device in, THAT'S WHAT THIS IS FOR! If you are going to make a product make sure it does what you say it does. Why even make this?

This product works it let me connect my two monitors to it and lets me switch between them to my sound bar system I can Regret it at all sounds comes out perfect

I have a desk setup with three different computers used for different tasks, and I figured one of these may be a good way to switch between the audio on each of them. I had been using a push button switch, but it only allowed for two inputs, which didn't fully meet my needs. Unfortunately, the noise isolation on this thing is pretty bad, and the electronic noise from my nearby phone and USB devices is enough to produce a constant hum from this, even with a ground loop isolator added in-line to the speakers. I'm not sure why this one has hum and my other one didn't, but it unfortunately rendered it less useful for me than the other switch which didn't have enough inputs.

I have four input sources (a radio and 3 computers) to put into one amplified speaker. This product does the job well. I haven't noticed any static or crosstalk and the rotary switch is solid. About the only improvement I would like to see is to reverse the labeling so that the plugs are on the back of the unit while the legend on the top is properly readable from the front. I had to turn it around and now the legend is upside down. Although it would increase the cost, I also wouldn't mind a volume control. But all in all, the price was right and it works as advertised.

Sound quality is good when only one input is connected. Once a second one it plugged in there is a very significant feedback. It is so loud that the device cannot be used. There is no feedback when I used an older switch that I was trying to replace with this unit. UPDATE: One of the other reviews suggested the need to add a ground loop noise isolator into the curcuitry. I have done this and the noise is gone. That ability should be designed into the device. As is, the added isolator was only about $10.

Muy bueno.

I'm using this as a switch between headphones and speakers, so I can't rate its ability to handle multiple inputs. compared to my old planetronics switch this does everything it needs to do. Well built casing and nice positive dial switch. Unit is smaller than the pictures make it appear. It's a tad over 3" long and an inch wide (footprint). Very nice positive contacts when plugging in 3.5mm cables. Compared to plugging in direct to my laptop this doesn't add any extra headphone fuzz or feedback. No obvious loss of audio quality.

Macht was es soll.Gute Haptik, ich habe nix zu meckern.

それなりのポート数の音出力切り替え器を探している方にオススメです。

This is only 3 1/2 in long. Fits 3.5 Stereo jacks in and out and is a good way to fit several the input from 4 gadgets to one amplifier input.Good quality construction.
