Hello! I do not know if either one of you experienced the following problem. During work outs I listen to Pandora. Everything is excellent for the first... 2 hours or so. Then, all of the sudden the voice mutes. I tried to change the channels but it does not fix the problem. After that, I decided to shut down Pandora and open Slacker. I see on the counter the song is playing but I do not hear the music on my headphones. And yes, I checked the volume and it's on high! Did any one of you experienced the same problem? Thanks!
