I currently have a good mid-priced pair of headphones, the Sennheiser HD439. They sound great and I love them, though the one thing I dislike about them is that their clamping force is too loose. They seem to fall down on my ears, and even pushing on the cups them slightly makes them sound noticeably better. Would there be any way to increase the clamping force? The only thing I've though that could work, would be to try and bend them bit by putting them in between two boxes, slightly bent inwards, and leave them like that for a while, but I'm afraid that the headband might break doing that. Other people recommend putting an elastic around the headphones while you have them on, but I have no idea how to do this, and I havent been able to find a good picture to show me. Anyway, could anyone tell me if theres any way to increase the clamping force permanently/ at least long enough to last a day, or how to use elastics to increase it for while I'm wearing them? If so that would be great!!
Thanks in advance,
