Quote John Willett:
I have various things from various manufacturers.
But with the K701 it seems that the consensus is that it needs a very long burning in time and I think about 500 hours is the norm for these.
500 hours? shurely shome mishtake? That's 21 days of solid playing(!) Blimey, pleased I went with the DT880s, now. They did need some burning in, mind.
