I have a few times, tied a headband around the k550's to get a richer and better sounding bass. I have been always thinking about some way to modify them to get a tighter clamp. Bending the headband helped but they could use more. I think that maybe a C shaped piece of wood glued to the band, or a bent metal rod could work. But they are so beautiful and I don't want to ruin them, and I would have to put extra padding in the ears if I did that. And the extra pressure really only makes the bass sound a little better, it's not a huge deal but I would appreciate it if I could do it.
So would you recommend something like this
