Headphones are just better for so many reasons, are people really still playing without them?

Yes. I’m currently forced to using a headphone because my 5.1 receiver died and I’m waiting for a replacement. I absolutely hate the feeling of continuously having something on my head for extended periods of time and can’t wait until I can game without one again.

For me better sound placement simply does not offset the discomfort that headphones or earbuds give me. So I respectfully disagree with you: headphones are not better for everybody. But of course choose whatever suits you best!
