New Apple Firmware damages headphones?
There is a rumour going around that the firmware in the iPod Classic (Version 1.1) could damage your headphones.
The problem is the firmware apparently causes an imbalance which sends residual electrical pulses through both the headphone jack and the docking connection. These pulses have been measured to be as high 500mv which it is claimed is high enough to upset attached equipment and potentially damage headphones.
At the moment this is just a rumour and Apple haven’t commented yet.
