    Comments about Polk Audio UltraFit 500 In-Ear Sports Headphone:

    The earphones connect to a cord that is then plugged into your music source. The connection on now my second pair (after returning the first) is not a clean snug fit, so you will find the music either is in one ear or out of phase. You wonder if the manufacturer really did any testing as advertised.

    • Primary Use:
    • Working out
