Hey there. I just recently found that I have a peculiar problem with my iPhone. The speakers work just fine, but when I listen to music or podcasts with headphones on (I've tried four different pairs), the sound is.. uhm.. weird, to say the least. Sometimes the vocalist on the song is quieter, a certain guitar is really loud, while another one is on heavy reverb and quiet.. I can't really explain it. It's like the sound channels have somekind of problem. Maybe I can provide a sound sample? Anyways, any ideas on how to fix this? Maybe I need to clean my headphone jack, or worse even.. get a new one? Thanks in advance.
