I'm not sure if this has to do with the headphones that come with it because I haven't noticed with them off. The volume usually is very low and then every now and then it will get loud to about normal levels. Usually ill have it turned all the way up and it sounds like it is maybe 4-5 bars off from max. Then all of a sudden it will start to blast at normal levels and then randomly it'll go back to lower volume. The volume rocker is never touched and when I check its always on max. Anyone having this problem?
