They get to my list of highest decibel headphones since they have a sensitivity of 110 + -3 dBs. 2016-10-08 A young, healthy human ear can detect a 3-decibel change in sound. A decibel is a unit of measurement used to measure the intensity of sound. Normal conversation is in the 60 to 70-decibel range, while a whisper is 25 decibels.

Decibels & Damage. Sound is measured in units called decibels (dB). Sounds of less than 75 decibels, even after a lengthy exposure, are unlikely to cause hearing loss. However extended or repeated exposure to sounds at or above 85 decibels (approximately the level of a vacuum cleaner) can cause hearing loss. 2019-06-22 Due to the impact of continued exposure to loud noise over time, usually the younger we are, the better we hear. The ‘normal’ hearing frequency range of a healthy young person is about 20 to 20,000Hz.Though a ‘normal’ audible range for loudness is from 0 to 180dB, anything over 85dB is considered damaging, so we should try not to go there.
