Does work for quick charge on both ports but also kicks out of quick charge when you plug in two devices. a little long but otherwise amazing. The large foam tips I had at times would not fit in the case and gets clipped or flattened by the top cover when it?s closed. Im not willing to pay $25 for something I cant use just because it has the Nike check mark on them. Das Gerät ist für den Einsatz in Konferenzen gedacht und funktioniert für diesen Zweck bestens. It does not look like the strap is removable. If you have nice headphones, in my case the hd6xx, dont expect the same quality. This headset works great with my Ps4, played right out of the box. Its been through high and low altitudes, high and low speeds, high and low breeze and wind gusts. My feet generally dont smell but it is 100% guranteed if I wear these flips for a few hours.
