Llego súper rápido! I’ve been wearing Birkenstock’s for years. I am 53 weighing in at 185 pounds and I measured my waist at 34 inches. My ears are on the smaller side and ear buds fall off easily so happy that their changeable grips and rubber has a size that fits me. The only thing I dont like at this point is the packaging. I highly recommend making your own template by placing a piece of paper or cardboard on the back of the bracket, punching the holes, and using that to mark the wall. At least not in my case. Pros:- Premium materials (metal and leather all feel really nice in the hand, no creaks or flex to be found)- Gorgeous- Bluetooth connectivity is flawless in my experience. They are great for classical music. 4 holes in my bathroom wall and 20 minutes later its finally installed.
