... the left driver is defective... AGAIN! No driver crinkling issues, this time, however... just significantly uneven volume compared to the right driver.
This is extremely odd because Brian said he tested these out before shipping. It seems that these headphones may not respond well to cold weather environments during shipment. This is the only theory I can think of....
I don't believe that the cold weather environment during shipping has anything to do with it. I ordered the AKG K551 during late December when we had very cold and bitter temperatures and I have not experienced similar issues. During shipment and packaging though the headphones are also protected by several layers from sudden changes in temperature usually with styrofoam and bubble wrap and finally the box packaging/box itself.
I agree it doesn't make any sense but perhaps there is a certain amount of defective units from early serial production. Considering that it was only announced late last year and is only currently in the early stages of production there might well be perhaps a few defective or problematic headphones that were shipped to customers.
I would like to get an AKG K545 to complement my K551 but at this point I may just hold-off and give the production line some time to mature and for any kind of issues to be caught and fixed/modified half-way through production or later in production. I'm sure that within 6-9 months the production line should be stable and the early production issues would likely be fixed.
