Headphones to sleep with. It's a big stretchy headband with flat speakers sewn in, and it works on Bluetooth (speakers are removable with a little effort to wash the band). I've always needed stories to fall asleep, and now I can't believe how many years I spent propping my phone just-so against my ear to not bother my sleeping partner.
I know i may sound like a boomer but it's not great for your sleep quality to sleep with sounds. Im not a doctor and i don't know how it work in your country, but you could try CBD oil, doctors can prescribe it where i live.
I set a timer to turn it off after 45 minutes or so, but it's much better than not falling asleep at all. And at 3:00 when I wake up again, I set another 45 minute timer. I'm not sure what the issue would be with my sleep when I'm only listening to droning voices. Maybe if the symphony snare drum kicked in it would be disruptive, but what I listen to is almost white noise with words.
I smoke weed to fall asleep nightly. That's also very helpful.
