Beats by Dr dre studio going fuzzy?

When i turn the volume up past the half way mark on my iPhone the music goes fuzzy, getting worse as it gets louder?
Any explanation/solution?
I've tired a different wire and different song, different phone still nothing

Yeh, the drivers have gone faulty. If you have warranty then send 'em away for repair… Or just buy a pair of Sennheisers.
