Looking for a stereo mixer with at least 2 inputs for under £30

[Jack_213]

I want a stereo mixer that can take at least 2 inputs and put them into 1 output (my headset). The inputs will be my phone, PC or consoles so it must be stereo so I don't get sound through only 1 ear, a mistake I made recently by purchasing a mono mixer which I had to return to amazon. It also would be great if it could be under £30 however I could stretch a little bit if completely needed.
EDIT: I want all inputs going to 1 output simultaneously so I do not want a switcher. Also UK links would be great.

Sounds to me like you want a switch. You didn't say what jacks it should have, but here is an example 3.5mm switch. And yes, this is stereo.

Sorry I meant I want a mixer. I want to have all inputs going to one output simultaneously. Should've made that clear.

I know that's what you wrote, I couldn't think of a reason as to why you'd want that. I thought you were wanting something else. My bad. I have no knowledge of mixers, hopefully someone else will come along.

No Problem. I am considering a switcher still so it was useful.

MERGED QUESTION
Question from Jack_213 : "Can someone explain to me exactly how this mixer works and what it's purpose is?"

Mixer: https://www.amazon.co.uk/SoundLab-Channel-Stereo-Microphone-Mixer/dp/B0048FBBS8/ref=sr_1_1?ie=UTF8&qid=1514643140&sr=8-1&keywords=Stereo+audio+mixer

So I want a new mixer to use for my phone, PC and game consoles. I talk to my friends using an app on my phone because they don't have PC's however I still want game sound so I found out a mixer is a good way of getting multiple inputs to one output. This one is quite cheap but appears to still have a few inputs and it is stereo. Does anyone know if this would work with the things I want it for? Also if you could explain how many inputs it has that would be great because it has so many input ports but is 4 channel.
If this mixer would not work for what I want can anyone recommend one that is cheap and on UK amazon? Thanks!
