For some time now, it has not been a completely strange image to see someone at festivals or concerts with AirPods. You’re not listening to Spotify (that would be weird, frankly), but using them as earplugs to muffle the noise. The trend has spread to such an extent that Apple now has an official name and has cataloged the trend with technical documentation. But… do they really work?
Since when? On October 28, 2024, along with the first wave of Apple Intelligence, iOS 18.1 arrived. In that updatethe AirPods Pro 2 received three new functions: hearing test, OTC hearing aid mode with FDA authorization and the one that interests us: Active Hearing Protection. Apple had been presenting it for months in keynotesbut finally, with the software came the legitimization of the company that they had been observing the behavior of users at concerts for some time.
How it works. Apple’s official documentation Sets three levels of protection depending on which mode is active. Transparency, which lets you hear the stage through the microphones, attenuates between 11 and 15 decibels. Adaptive mode, which mixes Cancellation and Transparency depending on the environment, raises that figure to between 25 and 29 dB. Pure Active Noise Cancellation averages 27 dB according to eardrum measurements from 2023, although the attenuation is not linear: at low frequencies there are notable improvements compared to the first generation; At mid and high frequencies, performance varies with the physical fit of the headphone.
No more than 85. And there is an even more specific mode: the algorithm in Adaptive Transparency (an activatable mode within Transparency) detects the 85 dB threshold and compresses everything above it. In a room at 110 dB (usual level at rock concerts or electronic festivals), that means reducing the peaks to around 82-85 dB. The subjective result described by media such as TechRadarwho tested them in a room with 114.7 dB peak, is that the sound is comfortable and with good nuances for bass and percussion. On the AirPods Pro 3, released in September 2025, the dynamic range even improves.
Of course, if the volume consistently exceeds 110-115 dB, even with 25-29 dB of attenuation, the user is exposed to hearing fatigue after ten minutes using AirPods Pro 2 in adaptive mode. That is to say: AirPods reduce damage and are a better option than going to the concert without anything. But they are a worse option than a calibrated hi-fi plug.
The fashion of the plug at concerts. According to Loop manufacturer datathe main users of hi-fi earplugs at concerts are young people millennials and Gen Z. Videos with tags like “hot girls wear earplugs to raves“, and the earplugs appear in lists of “rave essentials” as a meme. Hearing protection is no longer a thing for older people or sound engineers, and is now a hallmark of festival identity.
In fact, it is Loop itself, founded in Belgium in 2016, that has pushed this change. Their Experience models reduce 17 dB with flat attenuation, which means that the tonal signature of the concert is maintained: everything sounds the same but at a lower volume. The comparisons point Because Loop lags behind specialty brands like EarPeace or Alpine in pure attenuation quality, but the difference is negligible to the non-music user. Design, as with Airpods, plays an important role in its success. Of course, the difference is that people already have the Apple device for other purposes.
Why Airpods are not earplugs. The most relevant technical difference between a hi-fi earplug and AirPods is not in the number of decibels, but in how the sound reaches the ear. A plug like Loop or Alpine attenuates acoustically: the physical material absorbs sound energy before it reaches the ear canal. AirPods, on the other hand, capture external sound with microphones, process it digitally and reproduce it modified through the headphones’ speakers, so there is a dependence on the battery and the physical fit in the ear, just as Apple itself warns.
