Hi all. I recently acquired a pair of Grado SR 325 is headphones, which sound pretty amazing as far as I am concerned.
I have one gripe however, as when I listened to a few tracks in mono, I found the sound to be slightly skewed to the left (eg the left driver was playing a bit louder than the right). Today I brought out a sound level meter, and indeed I am finding that there is a difference between the drivers of up to 2 dB (1 on average, I tried a few different frequency signals). Is this normal, or should I get these replaced?
On the Grado website I see they claim matching to 0.05 dB, so based on that the headphones would clearly be defective. However, I have learnt to take this sort of manufacturer spec with a pinch of salt, so I am asking here before taking any action :-)
Thanks in advance!
