Query: Great but some reliability issues.

I would have loved to give them 5 stars. BUT there is just one thing that came up that prevented me from giving it 5 stars. 2 weeks into my ownership of these sonic bliss generators. It developed a hollow clicking noise originating from the left speaker. This was only present on low frequency bass music or movie scenes. I don't think it was a issue with the driver or transducer like the other people had due to the fact that I think my issue was a cabling issue. If i were to bend my head the slightest degree (the point where the cable meets the headphone then also bends) that clicking noise would appear and disappear. (personally I am not for giving myself a neck cramp while trying to watch a movie). Other than that issue, they are a beautiful sounding pair of headphones. I returned them for another pair...if number 2 is faulty then.....i guess beyer will lose a customer.
