I also got a pop in the pair I have had on loan. It was much better than the previous pair though (from a year or so ago) which was a disaster - the display had a mind of his own, the motor was resonating and there were constant pops when the music was laying. I could not belive souch a lousy engineering in a such an expensive product.
The last pair seemed to work OK though (apart from that pop on start up).
