I would say buying things is not a hobby, it's that simple. Sure, finding that one thing you like can be difficult, but just getting more and more? To me that's an obsessive behavior driven by fear of missing out on something, or idk, the attempt to fill some sort of void in your daily life. But that doesn't mean that everyone is nuts here. I too have been in this trap, bought many thing I didn't need and so on. It just happens and advertisements, reviews and opinions on here fuel this process. However, I've somehow learned to not fall for this lately. My 6XX does plenty and heck, after long sessions with the HD800 at a friend's place I still love my setup just as much, if not more.

I also can listen to music with almost anything, as long as it's not too muddy or absolutely spicy in the treble response. Sure, I love my setup, but a pair of good budget IEMs does plenty and gives you 85% of the experience, if not 100.

So I personally, as a friendly advice, recommend to focus on the music after you've invested into some proper gear and by that I mean one pair of headphones or IEMs with the potential dac and amp, if needed. Headphones and IEMs became so good that chasing some sort of endgame is just unnecessary for most. Sure, if you have the money to burn, go for whatever, but spend your money wisely, no matter what your income is. Things you don't like can still be sold, but I personally would not hoard headphones.

Btw I can already smell the downvotes lmao. But I don't care. Spend your money wisely and responsibly!

Cheers, have fun listening!
