I swapped my sim from my note 9 into the phone and couldnt get the phone to acquire mobile data or service. The item arrived on the 12th and they were released the 9th great shipping time ! They have an oval shape to them which conforms to the ear. You really sweat and loose inches from your waist. Se obtiene lo que se describe en los detalles, la funda de carga no parece de buena calidad. The original Bose ear pads on my headphones started to rip open slowly after a year of steady use. Lesson learned. The speaker has now been "updating" for a couple hours and its constantly "searching for speaker. Not gonna lie here. I didnt see this before I purchased the headset, otherwise I would have had second thoughts.
