As the headline say's, 5 stars, GREAT wireless earbuds.
I use these for activities like cutting the grass or working outside when I don't want to listen to binaural music. Also nice because when I am working on my car/bike/whatever, I can pull up youtube videos to help and people don't know that I'm watching a tutorial :) The sound doesn't leak one bit compared to other earphones/
About the binaural effectiveness part, yes it's very noticeable. I have the apple earpods and I tested them both and the clarity of Spiritualbeat's earbuds are on another level for binaurals.
