I agree. Having different kinds is good but you don’t need 5+ closed/open back headphones. Same goes for IEMs or wireless earbuds.

I only buy things that have different uses so I have to justify it to myself before I even think of buying it. I like to try new stuff but I tend to sell/trade/return them if I don’t see a use for it. I got all of these for a cheap price used.

For exercise (Sony WF-1000XM4), for travel with strong ANC (Bose QC35 ll), for sound quality (Drop JVC HA-FDX1), for games/movies/shows (ATH R70x). I use the Sennheiser Momentum 3 as the default option as it fits my preferences.

HD 600 has consistent reviews.
