500+ Head-Fier
Every once in a while, but yeah not very often. They get sold very quickly and the HE-6 even more so recently. You can search Hifishark to find listings from many sites including Head-fi, but it also lists ones that are sold already: https://www.hifishark.com/search?q=hifiman+he-500.How often do these come up for sale?
I had a pair back in 2013 and regret selling them haha
I did this Audeze headband mod a few weeks back. It took some time to find the right size screws, washers, and spacers, but the Audeze yokes fit perfectly now.
Next order of business is to build a better cable than what came with them.
I'm using them with Hifiman Velpads, replaced the grill dust cover (with organza fabric) and with EQ, they are right up there with my Focal Clear MG Pro. Even better in many ways actually.
