In french we have an expression "Tout vient à point à qui sait attendre". The best traduction a can offer is "Everything will come great for the people who know waiting". I know, it's not a great traduction, but the point is that the wait was long, but the final product is just great.
I have my Kokoons for two weeks now, and I just love them. They are sold as a product to help people sleep, and actually they are pretty good at it (the "cooling system" can be improved I think to be more "breathable"), but they are really good for everyday use too. I listen to my audiobook and my podcast with them and it's just perfect to create a "bubble" to concentrate and be focus on the story.
The lifetime of the battery is perfect (so far) and the auto-off feature is just a nice thing to help to preserve it.
Bottom line, I love my new Kokoons!
Bottom Line: Yes, I would recommend this to a friend
