The S9's appear to be very limited in either range or directionality - especially when OUTSIDE.
While at the gym, the BB in a small "fanny" pack at my hip pocket area works fine with almost no breakup in signal. Same fanny pack in my house in same hip location , fine, walk out the door and it starts to break up badly. So I presume that the BT signals bounce off surfaces in the house/gym (I did not think radio waves did that kind of reflecting) and reach the BB but once outside, the BT signals just radiate into the air.
What I've found does work, place the BB in the top flap pocket of a small day pack - kind of at the base of my neck or shoulder blade level and that generally does work fine for walks - 4 miles or more and continues to work with only rare break ups. I don't use headphones while biking - just my issue having been struck from the rear, I want to hear death coming the next time!!!!
