Rumor: iPod Firmware Damages Headphones?

Word on the street has it that Apple’s firmware (ver. 1.1) for the iPod Classic might cause a serious electrical problem, sending residual electrical pulses through the headphone jack and docking connection. These pulses claim to measure as high as 500mv which could damage upset attached equipment such as headphones. In addition, there are folks who have reported that audio quality has suffered since installing the update, being introduced to foreigners such as hiss, static and buzzing while listening in. Are any of you iPod Classic owners out there suffering from the same problem after upgrading to the latest firmware? Apple has remained silent on this issue so far though.
