I'm a big fan of the AcousticSheep SleepPhones, marketed as pajamas for your ears. When my CLASSIC version finally gave out after several years of almost-nightly use, rather than replace the cord, I decided to try the Simple wireless version and then switched to the Effortless.
- 20-hour rechargeable battery life (in the video I say 8 hours)
- Six timer options
- 17 pre-recorded tracks
I'm returning these not because they don't stand up to the description, but solely for personal preference with the pre-recorded tracks. Check out the video for my opinion. *Note in the video I say Effortless at the end. This version is Simple.
