I created my sleep track with those and for the first time in months I had a really good sleep, woke up early in the morning well rested and just ready to start my day! It feels amazing!! Thank you!!! 
My combination was A B C E F... but at beginning of F I woke up slightly and took the headphones off as they started to feel uncomfortable, still could sleep well for few more hours though.
Awesome, thanks for sharing your results!
