I, for one, think something goofy is going on with his pair. I often get the same impressions as he does on gear, but the bk I had (and sold) did not sound like he describes.
There are recent report of BK sounding very veil in China as well, and the suspected culprit is either faulty or even fake driver being used (*not unheard of for people to swap out real driver with cheap stuff then resold the earphone as real stuff for a high price, then resold the driver as real replacement for more money). I have heard story from one of the well known earbuds maker that people swapped out driver and sent it back for repair hoping it will be replaced with the real one. Not saying this will be the case here, but it is best to get your more expensive earbuds from a trusted retailer.
