justo lo que necesitaba Der Funktionsumfang, Optik, Haptik, NC etc hat fuer mich auch bei dem QC30 gepasst - mit einer gravierenden Ausnahme. Super loud, quite impressive for such a small package, waterproof for the pool area and overall a great buy. If you want to keep you charging case safe, sure. Plenty strong for length. Heel/ straps don?t stay put. Très déçus du suivieCommandé et le lendemain tarifs en baisse, pas tre cool jai donc demandé le remboursement de la différence, bien Reçu ! Update after 3 weeks, stopped being as accurate due to losing contact with the battery I believe. This is a repeat purchase. After an hour of intense ,mind boggling ,just force it in screaming and cussing and drooling it was finally together.
