M1 2 in 1 Out 3.5mm Stereo Audio Switch aux switcher Speaker selector Splitter Box

I have two of these daisy-chained together, one to switch inputs between my laptop and an Amazon Echo Dot, and a second one to toggle outputs between headphones and an external speaker system. Before that I had to constantly unplug and replug, and sometimes chose not to listen to music at all because I didn't want the aggravation. Another review mentions compromised sound quality, but I am not experiencing that, even running the signal through back-to-back devices. (Granted, my system is not high end audiophile.) When I first set things up, there was a horrible hum/drone sound that would have been completely unlistenable and unacceptable and I was ready to put them back in their boxes and send them home to Amazon. But in troubleshooting I realized I had not completely seated one of the connecting cables. Pushed that plug in until it clicked and all is well.

This little gizmo is working nicely in my configuration. I had expected there might be some issues, but everything is working swimmingly for now!

UPDATE from 1 star to 4: I bought an isolator, and plugged that into the offending input, problem solved. The hum issue is not really with the product. Its a grounding issue with one if the input devices. Here is what I used.

This should be a simple mechanical DPDT switch and wiring (there are no electronics involved), but there is clearly some shorting going on. I think its probably within the cheap pushbutton, I could not find anything on the PCB. I love the case so am keeping that, and replacing the guts with panel mounted versions and hard wiring it.

I've only just received this product so I can't speak to how it operates after extended use. However, so far the quality of the audio pass-through is decent. Through one of the jacks, anyway. The second split jack doesn't click right, seems like the internals have are loose or have too much gap? If the connector in that jack isn't set just right the audio cuts out and/or generates feedback/static (depending on the speaker type). If not for that issue I could give this 5 stars.

This is a minimalist but attractive little device that lets you connect two audio devices (in my case, an HDTV and a record player with internal pre-amp) to a single audio output (in my case, a speaker bar). This is a mechanical switch, and does not require any power, as it just flips from one audio circuit to the other. This device will let you select one input or the other. It does not have any capability to mix both audio streams together into one output. Still, a very cheap alternative to an AV receiver or a second speaker.

I have no idea why I waited so long to search for a product like this. It's so much cleaner to have one set of headphones on my desktop, vs a pair for each computer (personal vs work machine). This is the easiest way for me to switch audio inputs between my two computers. There is no pop when switching between inputs. Some people have complained about audio buzz. My older personal PC is not as well grounded as my new work machine. It has always had a low level buzz or hard drive buzz that spills over into the system audio. This box does not prevent existing buzz. If there are any flaws or lack of grounding in your system, you will hear it. But again, my one well grounded system audio is clean, and the older machine audio is just as it always was, no better no worse. Great simple product.

My application: I have 2 PC's on my desk that I use with 1 set of powered active speakers. Currently I manually plug the powered active speakers into whichever PC I'm using. This switch device, if it worked, would have allowed me to attach the audio output of each of the 2 pc's to the inputs (outer jacks) of the switch, attaching the (powered) active speakers to the output (center jack), and being able to switch between the two with the push of a button. First the Pros: Product is well packaged for shipping. Product is very sturdy, enclosed in a very nice small aluminum case, and is the perfect size for my application. Switch button is sturdy, 3.5mm female connectors receive and release the male connectors with ease. This device works well with non-powered earbud headphones. Cons: Attaching the 2 PC's and the powered active speakers causes static on the powered active speakers. I suspect the switch shares a common ground between the 2 inputs and the output and does not completely isolate the 2 inputs from each other allowing for electrical interference between the powered active speakers and the 2 PC's audio. I'm not unhappy with the product, but it won't work as advertised for my application. It is being returned today.

Wire splitter didn't work. This splitter did the job perfectly. Easy to install, Easy to operate, No complaints.

La qualité des soudures n'ont pas l'air de très bonne qualité, car juste avoir un vêtement qui frotte sur le fil du casque suffit a faire grésiller, voir couper le flux audio, il faut toucher au niveau de la prise jack d'input pour régler temporairement le soucis. Je préfère préciser que j'ai testés avec d'autres appareil pour écarter le fait que cela pourrais provenir de mon casque, mais j'ai écarté cette piste, c'est bel et bien ce commutateur qui pose problème

I was looking at kvm switches with audio and they all had iffy reviews.. figured I would just get a manual switch for audio and deal with the 2 click switchover. It's only a week old, but this was clearly the best decision.. this switch has no noise, doesn't pop when switching, and has a beefy metal chassis. With the separate audio switch I can get quick audio from the other computer without doing a full kvm switchover.

I can't use this device as it causes bussing and clicks, I would have hoped that being relatively expensive this would work perfectly. I still need to physically unplug and switch plugs because the device isn't working at well at all.

Professional quality, well designed and built device which functions exactly as intended.

I have two computers connected to one keyboard, mouse, and monitor. I was only missing something for the speakers and this did a great job.
