1st pair purchased for $150 and lasted 5 years until lost in the Pacific Ocean. 2nd pair were also lost. I am on my third pair and probably won't buy a different brand unless these get discontinued. Motorcycling, snow skiing, beach volleyball, etc. These don't fall off...
Pros: great fit, light weight, stay put,
Cons: none
