Posting: I received my RunPhones in nine days. That's very fast considering that I'm in Australia and often wait two to three weeks for items.
Item: I have not been able to run with them as much as I'd like, but that's more about my long work day. When I did wear them, they were perfect. I heard ambient sounds as well as my music. I also have worn them around the neck while cycling to work. I can hear the music as well as the sounds of approaching vehicles. I've also worn them as headbands about town. I hate earbuds. I find them nasty. I plan on buying another headband so that I always have a no-sweat one and a sweaty-nasty-sporty one. LOVE THEM!
