The video included shows me cycling through all the inputs. Neat little device that's easy to set up, and has a unique look. I didn't test it with Bluetooth to 3.5mm, or USB-C to 3.5mm. Review: Simple design. I like the interface and that it has a volume knob. You will need to turn the volume up on computer and speakers and then control volume from the unit. Otherwise, the sound will be too low. I like that the dial selector and not just a button that may fail. However, the big issue I have is that when I have more than one source cable plugged in, I get a buzz in the speakers. If I unplug one of the cables the buzz goes away. From research, I see that passive switchers have the issue. Two laptops plugged in cause a ground loop. Unplug the laptop and the buzz goes away. Also, it’s very simple just to plug and unplug the 3.5mm cable on one of the sources to relieve the buzz, but it kind of defeats the purpose of the device. That is still easier than swapping cables to speakers. ## Features - 3.5mm AUX cable Stereo Audio Switcher - 4 ways input, 1 output / 1 IN,4 OUT - Compact size Audio Signal Switch box - Select knob and Volume control on top - No need power supply, plug and play directly ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08F1ZNSQR | | Guaranteed software updates until | unknown | | Item model number | AU41 | | Manufacturer | Zhuogang | | Product Dimensions | 8.7 x 6.9 x 2.8 cm; 100 g | ## Product Details - **Brand:** SOLUPEAK - **Cable type:** Auxiliary - **Colour:** 4 ports 3.5mm switch(4 IN 1 OUT) - **Connector type:** 3.5mm Jack ## Images ![3.5mm AUX Cable Switcher, 4 Input 1 Output, AUX 1/8" Source Stereo Splitter, Audio Selector Box, Signal Switch with Volume Control for Home Audio - Image 1](https://m.media-amazon.com/images/I/61ePKczsa7L.jpg) ![3.5mm AUX Cable Switcher, 4 Input 1 Output, AUX 1/8" Source Stereo Splitter, Audio Selector Box, Signal Switch with Volume Control for Home Audio - Image 2](https://m.media-amazon.com/images/I/61lQsgyzQ1L.jpg) ![3.5mm AUX Cable Switcher, 4 Input 1 Output, AUX 1/8" Source Stereo Splitter, Audio Selector Box, Signal Switch with Volume Control for Home Audio - Image 3](https://m.media-amazon.com/images/I/61ZmePrf0wL.jpg) ![3.5mm AUX Cable Switcher, 4 Input 1 Output, AUX 1/8" Source Stereo Splitter, Audio Selector Box, Signal Switch with Volume Control for Home Audio - Image 4](https://m.media-amazon.com/images/I/612e9yQDAJL.jpg) ![3.5mm AUX Cable Switcher, 4 Input 1 Output, AUX 1/8" Source Stereo Splitter, Audio Selector Box, Signal Switch with Volume Control for Home Audio - Image 5](https://m.media-amazon.com/images/I/617YhSNsReL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by P***Y on 25 December 2025* My only issue is that the labeling is upside down for my particular setup, but that's no biggie.
