Yes… in the cassette players that work with those adapters. Annoyingly, the old stereo we have set up at work in one shop doesn’t work with those casette adapters or the Mixxtape.
Also, if you use it in a tape deck, it doesn’t use the spools as inputs. You just set it playing and pop it in. Similar to my old Digisette Duo Aria.
I will admit, I have rarely used the tape deck function, but it has been useful on occasion.
