I use this pillow speaker. I put it under the pillow lined up with my ear and can hear it pretty well with my partner heading nothing. Cons are you can feel it a bit if you use thin pillows, it can slide around making it hard to hear.
I too was very much in the “need to listen to something” camp. Getting the iPhone 8 meant losing the headphone jack so I took it as an opportunity to train myself to not use it. It was a rough few weeks but now I can fall asleep without it, but still have restless nights every once in a while.
This works great: http://www.amazon.com/Sangean-PS-300-Speaker-Control-Amplifier/dp/B00BB5WC8Q/
You stick it under the pillow and the sound comes through just fine. Not wearing headphones of any kind means there’s nothing to cause hurt. The pillow muffles the sound very well so it’s only audible if your ear is on the pillow above the speaker.
Pillow speaker, slips right in
(first one I googled)
Get you a pillow speaker on Amazon. They are like 13 bucks, and I play pink noise through mine for about an hour giving me time to fall asleep
Here is the one I use.
