If your neighbour can hear your music, it is too loud.

In-ear headphones at full volume can exceed 100 dB – as loud as a circular saw, right at the eardrum. The WHO advises: at most 60 % of maximum volume. Audiologists extend that into the “60/60” rule of thumb: plus no more than 60 minutes at a stretch. Modern smartphones show your weekly dose. Noise cancelling helps indirectly: you turn it up less.

Useful: Ringing ears after listening isn't a sign of great sound, but of overload.
