A:AnswerHave worn these for about a year specifically for work outs. I sweat a lot! Never any problem. Have worn in rain. Great battery life. Good sound. Very secure - important when you sweat a lot!
A:AnswerThese are best without glasses, but I wear them with glasses all the time. They are more comfortable with glasses that have a very thin frame. I have metal glasses that are comfortable with these and I have plastic frame glasses that are thicker and become uncomfortable after about an hour.
