I tried on 520, 2x620 and 920. All the same, but maybe 1520 has better audio quality, guess I'll never know.

The 1520 audio is indeed improved over other Lumias , it has some kind of special Dolby enhancements.. I Have one at home

I think the problem here is that the inline control for track navigating and mic may not be compatible with the Lumia. Why not switch to Bluetooth headphones, you don't have to worry about the compatibility issue. LG Ultratone series, or Sol republic Shadow sound pretty good. I knew Beats are a genius marketer for their brand. Some headphones reviews sites and forums I've found Beats headphones have nothing more rather than powerful bass.
