DJ Promotion Agency Logo - Any Comments?

Hi folks, im back for your valued opinion again!

I have just designed this logo for my brothers dj promotion agency.

The headphones were drawn in cinema 4d r9 with the smoke effect and then rendered with dirt along with the background.

Purple effect was added in photoshop and then finally put together in illustrator adding the text and the gradient background.

My bro hasnt seen it yet but any comments are most welcome.
