We're always suspicious of anything that advertises ‘extra deep bass', and in the case of Sony's MDR-XB500 over-ear headphones, this proves to be well-founded.

But plug them in and it all changes. Any kind of subtlety in the music vanishes under the thick morass of sound.
The tonal balance is swamped by a fat bass, while a strident treble and rough midrange lurks in the background. Buy some iGrados instead and save £20 in the process.
