In fact, much of the objective “evidence” for this phenomenon is shown on charts with a scale of 1dB or less (i.e. This area of the transducer is quite different in headphone drivers, and the amount of normal use it would take to affect sound quality in a measurable way for headphone drivers is ridiculous. It’s true that larger loudspeaker drivers see larger amounts of material change over time, specifically in the surround, the part subjected to most of the flexing action.
Now, that’s almost true: your headphones’ drivers and housings will lose rigidity over time, but it won’t cause an audible change in the measured performance of the headphones-at least, not for the better. Such a loss of rigidity allegedly makes it easier for the speaker element to move faster, resulting in better performance. The idea is pretty straightforward-the materials headphones are made out of will lose their rigidity over time, as it’s subjected to repeated force and sustained heat. The myth states that the component that needs breaking in is the headphone’s speaker drivers. The popular belief that you need to “burn-in” a set of headphones with hours of loud sample sounds like pink noise before they sound the best is just that: a myth. Many manufacturers won’t comment on this phenomenon, or if they do: they shy away from telling audiophiles that they’re wrong.Įditor’s note: this article was updated on April 30, 2021, for minor changes to verbiage. So far, all the tests performed by various outlets online haven’t yet found objective data to support the idea that headphone guts actually change audibly over certain periods of time.
