Good wind and other noise cancellation. (using when bicycle riding) Sound quality very good. Volume good. Ear pieces are a bit bulky but that is probably where the good sound comes from and some of energy efficiency. I have only used it up to 4 hours before charging but I'm hoping they will live up to the claim of long use before charge.. Charging is quick. Bluetooth connection quick and controls no problem. The magnets are handy idea. I like the cable knowing it one or both slipped out of my ear I won't have to go looking along the road to find it/them. They stay in my ears quite well.
