I needed a better solution, and this was the cheapest one I could find on Amazon

This is the best solution I could find for mixing 2 3.5mm stereo inputs into 1 3.5mm stereo output

I work at home frequently and like to listen to music from my phone while I work but sometimes need to listen to audio from my computer; I needed a solution where I could listen to both (not simultaneously) without having to constantly plug/un-plug audio connections to my one set of computer speakers on my desk

It can run from 2 x AA batteries but that is not a good long term solution for a stationary setup like mine.

I don't use the balance/gain controls or the Aux input - so maybe there is a cheaper solution to my

This is a perfect solution
