Minidisc
Great format, but killed by the lack of digital transfer.
I still use it for portable listening as the makers of said device and the headphone manufacturer know more about audio than whateter shite Android phone manufacturer I get lumped with each year.
Got home deck, portable and a currently unused car deck.
Junked the in ears dor some on ear Sennheisers.
I tend to go for the less used better formats. My VCRs take nice paperback sized tapes and have a good SD picture
