These shoes were so comfortable the first time I wore them. So, great sandal but not the best customer service. It appears that the external body of the headphones is designed for long lasting wear and use. great product will be great for my rides. Love Easy Spirit???? When I purchased them, they cost $70. My pores feel tighter and my face seems brighter. Thats fine for now, because the only one I use voice commands for is the Christmas tree. It?s not a five star product. Regarding the lights themselves, they seem robust and well made, cast the longer throw tight beam I desired and are easy to install and adjust.
