Hi - I have a pair of HD580s that i've had for several years and the headstrap (i.e. the plastic band on top of yer head) has finally broken. The plastic has cracked in 2 right at the top.
I realise this is a 600 appreciation thread - but I'd be really grateful if anyone has advice about replacement/repair for its close,older cousin the 580....
I'm in Sydney by the way.
You can either order HD580 or HD600 / HD650 parts. Hope that helps, as they aren't too cheap.
