For about a year already, I use ASMR audio/visuals when I go to bed (strange, not even mentioned in the referenced post). I found they help me falling asleep (though, probably, not staying asleep). Also, not just any ASMR stuff does the job, there is a lot of ASMR junk out there. Plus, ASMR triggers differ in efficiency from one person to another, so I preliminarily assess if a particular recording might be good for me. Most of all, I like educational ASMR about history/culture/languages/etc.

Never got audio working in the bedroom.

Either the headphones are not comfortable or my wife gets annoyed.

And it has to be something which I don't need to 'get rid of' after falling asleep like headphones or so.

Absolutely. I forgot to mention - at around the same time I bought open earbuds (Samsung buds Live, to be concrete) which I found comfortable - they don't block external sound and I practically don't feel them in the ears.
