Which of these physical audio formats have you used?

Cassette and CD.

ill be 38 years old later this year. i would imagine not many, unless you got quite a bit of age on myself, would be able to claim anything older than cassette's as those seem to be pretty much 1980's/1990's as i would estimate much beyond the 1990's tapes were largely dead and CD's were more of a 1990's/2000's thing and you got the digital audio types of players from 2000's to date kinda blending there to. but still... i don't see CD's going out for a while because they are technically of higher quality than MP3/AAC files and if your going to buy music i would rather have a audio CD as this way you can rip your own MP3 or AAC files.

i still got a portable CD player from the early 2000's (mfg date is probably 1999-2000 or so) as i would say those really became nice and power efficient (and the anti-skip technology was a great bonus to) by around that time frame (maybe a bit back into the late-1990's) as i remember using some portable CD players from the early 1990's or so and they were battery hogs which sorta forced me to stick to mostly cassettes for audio on the go.

technically, i have messed with a 8-track a little but i don't really count it because it was when i was a kid messing with those things a bit from parents stuff and the same for vinyl records. but i never really got into music at all til basically 1992-1993(i was born late 1979) and at that time i know we had a CD player which means we had to have a CD player before that time as i would guess we got our first CD player between 1990-1992.

p.s. i have a Sandisk Sansa e250(2GB) digital audio player running Rockbox firmware (https://www.rockbox.org/ (it's free but only supports a limited amount of digital audio players) since about June 2008. i can't believe i already had that 9 years already as what i like about it is outside of the Rockbox firmware on it is that it has a user replaceable battery and a MicroSD memory expansion slot which is great as with those being cheap you can get 16-32GB cards for not much $$$ and store a lot of music on them as the built in memory is only 2GB (which limits you) but i got a 16GB MicroSD card in it which allows me to store pretty much everything i got. it's amazing how fast things advance as i would have killed for something like that back in the day when we had those power hog portable CD players and cassettes just were never that great but i was forced to use them.

We had a cylinder record player for a while (my cousin's). Lots of 78s, 45s, etc. I was always around reel-to-reels but I'm not sure I ever threaded and used one. For video projectors, yes. Also had walkman, portable CD player, etc.

i still use vinyl and cd

I used mini disc and cassette back in the 90s
