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.

It seems to be working the way it should. I am satisfied with it so far.

This is exactly what I needed in my particular set up. I'm using a pair of in ear monitors that are very noise isolating to the point where I can't hear my own voice when I talk on video calls. I switch between a Fulla Schiit DAC and a Rode VideoMic NTG monitoring jack. Both are connected to the same computer over USB. I can get zero latency monitoring on the mic because it presents as an audio out device and mixes in monitoring through the 3.5mm jack. It's complicated. Anyways, this is what I needed and I'm glad to have it. No audio issues, additional signal noise, or ground loop buzz that I can hear.My main complaint is that the button would get stuck sometimes in the pressed position. I thought it was the switch or a weak spring, but after taking it apart I realized the red button was rubbing on the hole in the enclosure. I used a round file to enlarge the opening for the button a tiny bit and now it moves freely in and out. Removing 1 start for loose tolerances. I would have rated it lower if it wasn't easy to take apart, fix, and put back together.

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.

Upon opening the packaging I price could clearly be heard flying across the room and hitting the floor. Thanks to my wife's keen eye she was able to spot the TINEY screw that flew out. Better examination of the main body not only showed a screw missing (the one that flew out) but another 90% out. (See photo) This was NOT the condition I expected to get a new product in. It seems to be working for the time being and that's the only reason it got the 3 stars it did. 1 star taken for shipping a product in pieces, another for sending a product that was possibly used and disassembled.... Unbelievable and Unacceptable IMHO

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.

I use my PC for TV and Music and I have a Kickass Stereo for Tunes and a Sound Bar for TV so I use this to switch between the 2. For some reason if I forget to turn off the sound bar #1 and I am on stereo #2 I get a small ac feedback hum but as soon as I turn off the sound bar #1 it goes away. All in All I am very satisfied with this small well constructed metal body device with rubber feet too.

Ordered something better.
