Review: Solid and simple audio switcher - I have a complex setup with my PC, PS5, EQ, mixer, and DAC/Amps all connected together. I usually route it all to my headphones but recently picked up another external amp paired with some passive speakers so wanted a simple way to switch from headphones to speakers. This does the job with no issues. Sound quality remains the same to my ears. No buzzing or hissing. Solid connections and the box is solidly constructed. It doesn’t require power for it to work. You can have it set up to receive one audio input and then select up to four different outputs (one at a time). So if you want to output to speaker only you select a switch and if you want to output to headphone only you select another switch, which is how I have it setup. Or you can input four audio sources and output all of them to one set of speakers or headphones. Super easy to use and solid switch controls.
Review: Great physical audio switcher with no need to be powered - Worked great for my use case although I don't need it anymore so I don't use it. I was getting some kind of ground loop with the way I was hooking up my headphone amp to my powered speakers. I always had some kind of hum noise which was very apparent when nothing was playing. Also the headphone amp I had always outputted to both headphones and speakers at the same time with no way to choose between them. This allowed me to at the touch of a button be able to stop audio from going to my speaker when I don't want it to, while also eliminating the hum when I'm not using them. I like that its just a simple physical switch and doesn't need any kind of power to functions. But I may have considered something else if it came with a remote to do the switching so I could activate it from my couch. It's my only small gripe I had with it and probably would have increased the cost if it was included in so I guess this way you can save money. It is a small lightweight metal box with probably very little circuitry inside but I didn't feel like it was light enough that it would be pulled off my desk. Its a good value for the money in my opinion and I didn't notice any loss in sound quality or other issues when using this product. Its built well enough that I don't think anyone will have any issues with it.

### ⭐⭐⭐⭐⭐ Great switching box
*by M***O on July 13, 2026*

Exactly what I was looking for. I needed a 3.5mm with RCA jacks and this fit perfectly. Everything functions as it should, the appearance is small in size so it doesn’t take up a lot of room. Connected very easily and is easy to switch between modes.
