I had trouble in the beginning pairing it because I didnt realize that you can only pair one device at a time. Doch was hat dies für einen Grund? Der Grund hierfür ist der Nackenbereich unterhalb des Ohres, an diesem geht der Kopf nämlich zum Hals über und wird somit schmaler. It works well The slippers are nice but not what I ordered. The clamp makes it handy to attach on to my purse or backpack. Though there is no active noise cancellation, the closed-ear design shuts out an amazing amount of background noise. As in other reviews these are at least s half size larger than advertised. played around with arm height to get sound that worked for me. Great productTook the plunge and ordered some aftershokz headphones loved everything about them except for the case that came with them. Bought this for my hon who had gotten a slow leak in her tire on a solo ride.
