FlyroadUp 3.5mm Aux + RCA L/R Bi-Directional Stereo Audio Switch 4 in 1 Out A/B Analog Audio Switcher Selector

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.

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.

This little box is exactly what I needed! I love that it has both RCA and 3.5mm inputs/outputs, which makes it super versatile. I’ve got my CD player, tape deck, turntable, and even an old-school iPod all hooked up at the same time. Switching between them is quick and smooth—no more plugging and unplugging cables every time I want to listen to something different. The build feels solid, and the sound quality is crystal clear with no noticeable loss or distortion. If you’ve got multiple audio sources and want a simple, reliable way to manage them, this switcher is perfect. Highly recommend!

Works as advertised. Switching between a turntable, Bluetooth receiver, and Android tablet.

I use an audio switcher in my home studio to route audio from two computers, and two Pro Tools Digi 003 audio interfaces. I switch back and forth between devices a lot, so I've gone through other audio switches over the years, most have had plastic bodies & switches and wear out over time. This particular swither has metal body with plastic mechanical switches & it is passive, meaning it requires no electricity or batteries to make it work. Because the witches are mechanical, they make a metallic noise when you engage them, no super loud, but not 100% silent either. The RCA inputs & outputs on the rear are nice & tight but not overly so. Several manufacturers sell this switcher, so I'm assuming they all come from the same factory in China and are rebadged for whatever company is selling them. Overall the construction is good, I'm not experiencing any noise or crossover, so I'm assuming the electronics are better than many other similar devices for sale here. Nothing fancy, and doesn't look as nice as the Sima switcher I had, but I blew through two of those in about 3 or 4 years, so they weren't as robust as they looked.

Low tech works for me. You can have up to four inputs with 3.5 mm jack or RCA plugs in and out

Hooking up an very good but old stereo amplifier that I have and needed to add additional inputs. This switch is perfect....they have other models with more inputs or types of connectors if that is what you need. The switches feel solid and make a audible click when selecting one. No noise when switching devices. It's nice that it has both a pair of RCA jacks and a 3.5mm jack for each channel. Can be used in either direction.

Put together a sound system for my office consisting of a 70's receiver, CD player, and 8-track player. This unit lets me run the CD player and the 8-track into the AUX input without having to swap RCA cables all the time.

Nicely finished, good price, does the job

good quality and works well, recommended.

I ordered this unit over many others as it has 3.5mm aux (headphone jack) as well as RCA. I wanted the flexibility but intended to mainly use the 3.5mm aux - nearly all the cables/devices I already had supported this. It worked fine for about a week before the main 3.5mm aux out started playing up (tried multiple cables to verify) and I had to change to RCA. I have now replaced all my cables to utilize RCA inputs/outputs which defeated the purpose of why I chose this unit. I would be very weary in recommending this unit if you intend on using the 3.5mm aux inputs/outputs. For now, the RCA seem to be working but I shouldn't have needed to change.

Been using this a while now, very good quality, no bleed over of sound, excellent quality product

It just works as should. Nothin more or less. Such a powerful little box without any problems. (Version of 6 connections would be nicely welcomed). Thanks for your attention.
