Query: Sound OK, but are very bulky & uncomfortable..

I have been using Sony 7506's forever. So comfortable. So clear. So flimsy. The cord is not detachable, so I have gone through three pair already with the cord always getting loose. Having said this, after doing a lot of online investigations, it seemed that the Sennheiser 280s were rated closest in sound, have a detachable cord (feature not available in Sonys) and were supposedly comfortable. They are NOT comfortable. Sure the ear cups swivel and they collapse so you can travel with them, and they sound almost as good as the Sonys, but not AS good.. So, I will have to stick with my clear, flimsy, but very comfortable Sonys moving forward.... Oh well..
