Beat me to it. Dangit.
Depends on what type of music, where, when etc.
At home, due to not living by meself, either via monitor speakers if it's not a criminally nice jam. If it is, either going for AKG K240s or Koss Porta Pros.
If I absolutely want to focus on listening to something, I either go for the WF-1000XM4s, LinkBuds S or recently even cmf Buds Pro 2. Latter are pretty fun to fiddle with when it comes to spatial sound.
Outdoors it's usually just the LinkBuds S. They are too reliable and durable and never disappointed me since.
As far as mediums themselves go, foobar2000 never let me down thus far, but I also dig listening to jams on a LP or even on tape.
I think I understand how women feel when they are addicted to collecting shoes.
My secret weapon will probably forever remain these. Love them to death. I just wish AKG didn't die the death they did.
