Video gamers, what do you use for sound?

My PlayStation 4 came with its own headset which includes a microphone. It’s great for playing together with someone online, as you can talk while you play. But the problem is that it only has one ear piece…so many headsets have that, am I the only one who finds it completely annoying? I hate hearing in just one ear. And when I’m done playing, my ears are ringing and I get all headachey. Why do microphone including headsets always have just one ear piece?

I have a surround sound system, but it’s too outdated and is not compatible with my PS4. So basically, for the console, I have two options; using the headset they give you, or I use the headphones from my PSP. (PlayStation Portable) But the mouthpiece doesn’t work on the PS4.
There do exist headphones with two ear pieces and a mic…but those things cost more than a game, some go over 100 dollars. I mean COME ON.

So for anyone who plays video games, can you tell me what you use for sound? I know for a fact that today, you can rig up your own system and customize the sound if you know enough about how all that works. Which I really don’t, but perhaps if some of you guys give me examples, I can try to work something out for my console and get a better audio experience. Obviously, any example that includes the PS4 would be great, but anything you play on will work, if it’s something you rigged up and customized yourself.
