Has anyone experienced any random skipping to next song while listening to the ibeats? When I'm at the gym I throw on a podcast and several times I got random fast forwarding and skipping songs entirely without coming close to hitting the buttons on the cord. Also I hear buzzing and noise coming out of the left headphone when I'm plugged into the wall or the screen is on. I might go back to the old iphone earbuds if there's no fix.
