Heya,
If you live in Florida, I'll let you check out any headphone you want and be the judge yourself.
Otherwise, there are essentially tiers. And it's all about what you want. It's all about refinement and having various qualities all in one headphone which is hard to get everything in one package. Consider, a 5.1 system is comprised of 6 speakers to achieve the sound field and cover all frequencies properly. A headphone tries to do it with two drivers. So what you're after matters. Quality of components, quality of build, etc. It all ties in. And the price goes up and up as you get more and more refined and it does plateau after the mid-tier stuff ($300ish range) to the point of probably insanity or novelty beyond comprehension (in which case, I'm insane).
I have $30 headphones and $50 headphones that honestly compare to some $200 headphones with some tweaks to EQ and some amplification to speed the driver recovery. I have some $300 headphones that blow away everything and compare to flagships in my opinion. It's relative of course and completely subjective.
Driving in a beater that cost ya $500 will get you from point A to B, but how well does it do it and how do you feel doing it? Stuff like that comes into play. Do you want to hear everything? Or just enough to get the idea? Do you want to feel like you have something luxurious on your head, or do you want to feel like you're wearing a cheap piece of junk that rattles instead of produces music?
What do you want?
Are you looking for justification to spend more than $30? Because I'll tell you, that's the cost of going out to lunch for me. And I do it all the time. I have headphones that were $300 that I still have, ten years later, that I still put on and go "Man, I love these." Worth way more to me than some lunch I had, 10 times. So again, it's all relative. You may think something is expensive now. But if you get it and keep it and use it for years and years, it basically becomes beyond worth it's cost. Nice headphones are an investment. They're not just an expensive trinket if audio actually matters to you. I'm treating myself to experience, to emotion, to a feeling. Something that money can't buy, but money can buy something that can actually give you a gateway to something you love. Do you love beautiful audio that is so good you get goosebumps? These are the things that make the difference between a $30 headphone and a $300 headphone, or a $1200 headphone.
How important, no, precious, is audio to you?
Very best,
