I’m glad you’re having a good time in the audio rabbit hole. :) The nice thing about trying a lot of “Standards” like the K371, HD600, and DT880 is you’ll then have a great idea of what your preferences are, and you can quickly skim a review of a newer thing and know whether it might be something you’d enjoy.
A good tip from those more knowledgeable than I, which I like to follow, is to give yourself about a week to adjust to a new pair of headphones, then quickly pop on your old ones to really get a sense of how they’re different. While I don’t really believe in physical burn-in for most pairs, “brain burn-in” is a very real thing. Audio and sense memory are curious, and our brains will slowly adapt to whatever headphones we use over several days.
Thanks once more for reading so much of my stuff, I appreciate it!
