These are great gear if your really wanting some quality buds that stay put and have great sound quality. With some ok sound blocking settings. My issue is that the call quality is hit and miss and I have no idea what's happening almost no time or reason it'll work great the with out a thing being touched they go bad and no one can hear me. That's my single reason for having them I'll up date if I get it worked out but the random changing is a real problem right now he call range from the phone is amazing the sound is great the stiff over ear hook is almost perfect but I can't count on he call quality so two stars for now !!
I used my sport anc 3 for a year in a cooler with high moisture and for a year working for a water utility with the bud getting hit with high pressure water at least once a week for that year and they worked great easily got my money worth I used them everyday even on weekends
