Don't waste your money or time. Read the other reviews. Shoddy materials and instructions and we couldnt get it to work. Buy one with an included antenna coil. The extra few bucks are worth it. This is the worst kit I have ever purchased.

I just bought these to replace a different brand that I recently lost. While they felt reasonably comfortable to wear they were completely unsuitable for jogging. When you run there is a loud drumming feedback in your ears from the bounce of your jogging motion. My other set had a small dongle on the wire that seemed to prevent this - I would not recommend these for exercising. Very annoying!
