Headband bought for modding

I was just watching Zeos review of the Monoprice M1570 and he kept talking about modding the headband for it. Like removing the old headband and replacing it with another. I was wondering if there was a place that sold just the headbands for headphones. the Audeze and ZMF headbands look so similar that im wondering if they source them from some place. Alibaba maybe or something?
