I have a decent sound system in living room that the TV plays through but I also wanted the desertcart Echo to play through it as I use that to listen to music when working around the house. The Echo is okay on sound but I wanted it on the big system to really jam out. So I went looking and found this little thing. Well I bought it and hooked it all up and BOOM! I have sound from the TV as I normally did and now I have some sound from the Echo to jam out to. There is no volume control for the device itself as your using the volume of the device you are plugging into it. This device is just actually combining two sources into one output with no onboard controls. This also worked in my favor as there is nothing for anyone to mess up. It has such a small footprint design it was really easy to install it and tuck it behind everything. Did exactly what I needed it to do. Review: This works great for splitting audio between two devices to a single speaker. Working great! - I've used this audio mixer for several months now, and it has been fantastic! I wanted a way to utilize the speakers I use with my PC, along with a Nintendo Switch. And I didn't want to have to fumble around with an aux in speaker wire every time I went from a device. This audio mixer allows me to always have my PC, as well as a Switch connected to the speakers. I don't push two audio streams to the speakers at a time...but it serves my purpose perfectly. It just works. It does require a separate power source to function, but once it is plugged in, and you have your audio devices plugged in, it works great. I would really recommend this little device if you want a way to plug in two devices that have "audio out" and you want that audio to go to a single "audio in".

Fantastic little device... ### ⭐⭐⭐⭐⭐ Crystal-Clear Audio, Zero Hassle—A True Game Changer *by S***N on July 16, 2025* This little mixer solved everything. I use it to connect two PC towers to the same speaker setup, and the difference is night and day—no more buzzing, ground loops, or weak signals. The audio is now crystal clear from both machines. It’s compact, well-built, and includes the cables you need to get started. I was so impressed, I bought another one to link two radio scanners to a powered speaker. Works like a charm. If you’re juggling multiple audio sources and want clean, reliable output, this device is a must-have. ## Frequently Bought Together - Cooidea 2 Channel Stereo Audio Mixer - Metal Shell, AUX Interface Support 2 In 1 Out Mini Stereo Sound Mixer Includes 1-Meter Audio Cables - For PC, Phone, Laptop, Headphones - 2 Pack AUX Cable, (6.6ft/2m, Hi-Fi Sound) 3.5mm TRS Auxiliary Audio Cable Nylon Braided Cord Compatible with Car,Home Stereos,Speaker,iPod iPad,Headphones,Sony,Echo Dot,Beats (Grey) - Nanxudyj AUX Cord 6ft/1.8M,3.5mm Stereo Audio Cable 90 Degree 3.5mm Male to Male Stereo Aux Cable Right Angle TRS Cable Compatible for car, Headphone,Tablets, Speakers --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/658552704-2-channel-stereo-audio-mixer-metal-shell-aux-interface-support](https://www.desertcart.co.uk/products/658552704-2-channel-stereo-audio-mixer-metal-shell-aux-interface-support) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-25*
