How? With my ears,
In practical terms, whilst sometimes I put music on as background while doing something else in the music room (I have a desk in there), more often I sit down to listen and intend to do something, but end up being drawn in to the music and forget all else… Only infrequently, when I have a good few hours free, do I plan to listen more seriously, moving the speakers and seat to optimum position, and no intent to do anything else at the same time: that is real bliss!
Otherwise when travelling (remembering those days when I could fly or take a long train or coach journey) I dump a couple of dozen albums (in .flac format) onto my iPhone and iPad, and usa a pair of Bose noise cancelling headphones. Not really hifi, but then the locations aren’t conducive either.
