They work perfectly for what I need them for. The last thing I want to say is, be sure you peel off the plastic film that covers the charging contacts on the earbuds during shipment. It was easy to assemble and is light weight. It looks very nice and it was easy to hang. I am very satisfied with the product. Getting replacements and will see what happens with that. They tend to be a bit pricey (although these are ok) which is a shame! As you can see in the photo, the shoe is now totally sloped toward out. On the other hand InstaNatural customer service is great! They are also great on packed snow.
