Hi Bizi,

Sometimes I listen to the 8 hour recordings of soft music (theta or delta waves) designed specifically for sleep. There are different versions. Here's a playlist of many different 8 hour recordings: 8 Hour Sleep Music: Meditation Music, Relax Mind Body, Sleeping Music, Calming Music ☯231 - YouTube

I don't last the entire 8 hours. I usually drift off before the first hour has passed, especially if I insert both ear buds. I awoke one morning, after having slept for 7 hours and the music was still playing, even though my ear buds were on the night stand beside my bed.

If it feels energizing, turn the volume down further.
I am very sensitive to sound, so I have to keep it very low.

I had started to listen to one while writing this and I think I will use it tonight!
The key for me is to make sure I am listening with both ears, low volume.

No need to try these unless they appeal to you. I am just sharing with you.

I hope you have a night of peaceful, refreshing sleep, however you go about it!
