I gather you meant music.  It's stereo 2.0 for me, as it's been since I was 12, though for several years it's been through an integrated with A & B outputs.
As a survey researcher, I suggest you always need an "Other" response category, optionally with a fill-in space. These days I actually am spending a lot of time listening through a Lenovo Tab Plus tablet -my lowest-cost stereo solution yet. This marvel's 8-speaker package sounds amazing for a tablet that I move throughout my home during the day, playing back my FLAC files, and especially streaming my Amazon Music subscription's HD and ultra-HD selections. No, it doesn't compare to my stereo, but I've found it more satisfying than I expected, and handier and more flexible than wearing headphones for portability; plus, unlike my nice Bluetooth speaker, it's loaded with all the software I need, and the battery lasts and lasts.
