I have a large music library that I don’t have much storage left for on my phone. There are of course other ways of solving this problem, but are there any good dedicated music players like iPods still around?
Ideally I’d like it to have Bluetooth functionality for wireless headphones, at least 512GB of storage, and an SD card slot. Possibly physical buttons as well.
I’m not sure how ‘modern’ this is, but you could pick up an iPod Video or Classic, whose audio section is still competitive by modern standards, and then flash-retrofit it and Rockbox it.
