These are great for taking the dogs out first thing in the morning. Gotten a coupon code too! The rest of the product was just fine. Macht Bock seit man sie aus der Packung geholt hat. It cuts off the mic for the wireless and switches over to the Bluetooth. AppearanceForm and function are great. Was certainly not disappointed. Will remove it after the use. This one seems like it will hold on tight. HOWEVER, when I turned on noise cancellation, my QC25?s emitted an ear-piercing screech (microphone feedback).
