First time caller, long time listener. I just picked up a shuffle 3G with the ingenious idea of setting it to go using the headphones, then switching to a pair of sennheiser headphones to workout. Great plan, but the headphone controls have already bit the dust. Just plugging in the other headphones works fine for working out, but the volume is a little low. Is there any program that will allow to set a floor for the volume? Thanks for the help.
