My wife won't let me sleep with the speaker, so I've adapted to have 1 earbud in depending on which side I want to sleep on. It eventually falls out and tomorrow I seek to the last place I remember in the book and repeat ;)

Hmm that sounds quite uncomfortable for what might be a common use case. I wonder if a parametric speaker would help.

Sure can! http://www.sleepphones.com/

I wear these each night and listen to relaxation videos such as ASMR [0]. Many people in that community use these.

The SleepPhones seems interesting... I hadn't seen them before. Just curious if you use the wired or wireless version?

I'm a big fan of SimplyNoise / SimplyRain, and also have a little one-line bash script colored noise generator that I use these days [0]. ASMR seems like a similar idea.

I use the wired version. Bought them on Amazon.

I've heard of SimplyNoise. I have used the RainyMood + YouTube webapp in the past. Pretty novel concept.
