Could not pair or work after day 1. It would have been nice, since the base has a USB connection for charging, to see a pass through USB port on the stand for the bluetooth adapter. 5 shoe, but rounded up to get the size 7-8 just in case. Attractive color and comfort. Take a look at the wear and tear of the Amazon Essential pair in the middle . These are well made,quality worth the money. They did come with green markings on the left shoe which I assume could be from the green box and green wrapping paper they came in. The only downside is that it can sometimes get really cold. Bought in black and white stripe and grey/black zebra. You really only need a small amount on your fingers to wash your face which is great.
