Only down side is if you have a spare tire mounted on the rear of your vehicle (like a Wrangler) then you cant open the door. $9 wasted. I loved them so much I immediately bought another pair to wear at my daughters house when I visit. I wish people would quit having expectations that a PLATFORM WEDGE sandal is supposed to be like wearing a Nike all day long. Comfy and I purchased pink. C’est une excellent idée, ça fonctionne, mais. The active noise cancelling is nice, It eliminates ambient noises but not all noises such as conversations. It cames nicely packaged. I also like the fact that the Monoprice has a built in li-ion battery, and I like the fact that the noise cancelling feature can be used without the volume-boosting electronics, so if you just want the noise cancellation for a long plane ride, the battery will hold out all that much longer. Im Praxistest gibt es nie Verbindungsunterbrechungen.
