I had to reboot my computer before it recognized the C5D. The volume started out pretty loud, so I quickly turned it down. I do not think there is any damage to the headphones. By the way, the C5D has a different frequency response, I think there is a slight rolloff in the high frequency range. This may be my imagination at this point. But the sound is still very good
However, when I disconnect it from the PC and plug it into my iPod Touch, I have to turn the volume up to the maximum for my DT880 250-ohm headset. Is this normal?
