Heavily used or poor quality headphones will rattle/buzz with loud heavy bass. This video tests that. The sweeping tone should remain pure, constant and smooth with no hideous rattle or buzz. Headphones which will pass this test include: - ATH M50 - Sony MDR 1R - Beyerdynamic DT 770 Those are just a few. Comment which others and I'll add them to the list. I cannot accept responsibility for blown speakers etc. It shouldn't happen however.
