From Pioneer's Facebook page; Pioneer Electronics Australia Pioneer was lucky enough to receive two pairs of the HDJ500 headphones in white, prior to the Australian release in early 2011. As a gift to the world's biggest DJ, Tiesto, Pioneer had these headphones engraved with his logo and presented them to the man himself last night in Melbourne at the 360 Electronic Music Masterclass. It was love at first sight for Tiesto, who not only signed a pair, but took a pair with him to use on stage at Stereosonic this weekend in Melbourne. For those of you venturing out to Stereosonic this weekend, look out for the HDJ500W around Tiesto's head! Anyone going to the Melbourne gig?
