They smelled funny from the moment I opened them, and they still do. However, one wants to wear sandals since its hot and we go back in August; yet you want to look professional. Although they are a steal for half the price at stores. I am a teacher, which means I use Zoom everyday, all day, and Im the one mostly speaking. Once it?s all together it?s pretty solid. As Fred Astaire sang: ?Put on your dancing shoes, stop wasting time; Put on your dancing shoes, watch your spirits climb! After that, it would only work off and on often enough to where it got annoying. Not great sound quality or bass for $500. But they are perfect, and I get compliments on the colors all the time. I love this thing it helps me keep my posture and also helps shape me!
