Review: Nice tiny switcher for audio components - I was hesitant buying this no-name splitter, as I have had bad experiences in the past with similarly cheap audio devices on desertcart. But this thing is doing its job, which is simply to route one of 3 stereo inputs to one stereo output. I am using it with two vintage cassette decks and an audiophile CD player and I can't hear any quality loss on my system after several A/B tests (I've got decent gear too including a Topping amp and Audioengine speakers). The splitter is passive, so there is no active signal from, for instance, a power supply or board capacitor, that would interfere with your analog signal. While it's certainly possible some of these units were made inconsistently, leading to the negative reviews, mine is fine, and it's also possible people are using low quality RCA cables or have inherently bad/defective RCA outs on their gear. Whatever the case may be, for the extremely low price, it's worth a purchase to see if it works in your audio system.
Review: It works exactly as I hoped! - I needed some thing for my computer to be able to easily switch sound output between my earbuds and my surround speakers. The inputs for both of my devices are 3.5 mm jacks so this works perfect with my computer. I do wish that the enclosure were closed off, so that dust wouldn’t get into the circuitboard. However, the size is nice and fits right on top of my desk. It was very easy to install, and although I was expecting there to be noise and popping whenever I would switch the outputs with the dial, I’ve not experienced that so far. The only problem that I have experienced is that sometimes the output tends to fade if I press too hard on one of the 3.5 mm output jacks, almost as if it’s not soldered on perfectly. Considering the price of the product and how well it solves my problem, I still consider myself a happy customer, and I would buy it again.

### ⭐⭐⭐⭐⭐ Nice tiny switcher for audio components
*by S***. on June 27, 2021*

I was hesitant buying this no-name splitter, as I have had bad experiences in the past with similarly cheap audio devices on Amazon. But this thing is doing its job, which is simply to route one of 3 stereo inputs to one stereo output. I am using it with two vintage cassette decks and an audiophile CD player and I can't hear any quality loss on my system after several A/B tests (I've got decent gear too including a Topping amp and Audioengine speakers).

### ⭐⭐⭐⭐ Lovely Appearance, Performs its Job Well, May Need a Ground Loop Isolator
*by M***O on October 13, 2020*

I picked up this handy little AUX Switch Box to tidy up my work from home / gaming desk setup and allow me to easily switch between my speakers, headphones, personal computer, and company laptop. The unit does exactly what I wanted it to do, but I did want to confirm that thanks to its simple design you will likely need to add a ground loop isolator ($4-8 ea) for each input beyond your first one. The 3.5mm jacks feel tight, and paired well with the random assortment of 3.5mm cables I've accumulated over the years. The selector knobs have reasonably positive detents, the aluminum knobs feel nice enough, and the overall package performs nicely. It even looks at home next to my inexpensive Bravo Audi headphone amp. My only real gripes are the lack of ground loop isolation on the inputs, and the layout of input and output jacks. It would have been a lot tidier if there were two inputs and two outputs on the front and back of the device to keep my back-of-desk arrangement nice and tidy, but I understand that it would have taken more work to get the PCB to layout nicely. Overall, I'm giving the switch box a 5/5 stars because it does its job, I was aware of the potential flaws with the ground loop isolation, and its affordable as all getout. I could have made something myself, but for this price, why bother? Pros: - Inexpensive - Allows easy switching between inputs AND outputs - Attractive, minimalist package Cons: - Some feedback if there are multiple grounded input devices - Input/Output jacks leave room for improvement Neutral: - You gotta install your own rubber feet Recommended Improvements: - Integrate a ground loop isolating transformer if space permits - Have 2 inputs and 2 outputs on the rear of the switch instead of 4 inputs on the rear, and 4 outputs on the front.
