I think it just comes down to the individual. At the end of the day, it'll be your money. For some people, a $300-$400 has 99% quality of a 700-1000+ headset. They could even go to $5000 headphones but it's still only a 1% improvement to them. At that point, that's simply diminishing returns and that money spent could be spent elsewhere in life or other hobbies. You can "know" there's better stuff out there, but you can also convince yourself that it's barely noticeable or it's really just something you don't need. You can instead use that money on other enjoyable things in life. It's kinda all mental at the end of the day once you hit a point where your ears might not actually be hearing better anymore and your brain takes over telling you there's better.
