Headphoneus Supremus
That HE500 cable is stiff and microphonic, and those yucky conectors on the earcups. But those cans sound great. The stock HD600 cable is both supple and free of microphonics.
I changed my HD600 cable out a while ago just because I didn't like how long it was. It's the only reason I change to aftermarket cables on all of my headphones: the extra length is annoying to me.
Also yes, the connectors on the old Hifimans (so anything that isn't the new HE-1000 or HE-400S) are just terrible to deal with.
