last night i was using my head phones on a call for a long time, i think it had been about 45 minutes to an hour into the call when all of a sudden i just heard this loud crackling sound and had to hang up. then i called the person right back and again about the same time it started crakling. this happened once more i think. the total length was like 2 and 1/2 hours ( im only 15 by the way). so i was wondering if there was a limit of how long you could use the headphones on a call, and if theere was a fix. or do you think it will get better with time? that was the longest i had talked to someone since i got this phone and plan to talk to the same person at least this much everyday so i really need a fix other than just putting it on speaker or holding it up to my ear. thanks
