I currently have my 20S connected to a Freewire and a Garmin 396 GPS. It works OK, but is very noisy with the signature popcorn noise that has plagued the 20S from the beginning. Does anyone know if the 30K is quieter than the 20S when it is used for multiple A2DP connections? Sierra will allow me to test a 30K in my setup if I want, but if it does not work better than the 20S, I would end up having to pay their restocking charge. I don’t mind spending the money if the headset is actually quieter, but don’t want to pay to test the headset if someone else has already determined that the 30K is just as noisy as the 20S. If I am only riding a couple of hours, the noise does not bother me too much, but after 6 hours or so it gets really frustrating. I’m also not wild about the shorter battery life of the 30K, but I can live with that. I put a 5000 mAh battery in my jacket pocket and connect it to the headset. With that setup my 20S will run for several days without battery power issues.
