The AirPods Pro 3, released on September 19, 2025, face significant issues with the active noise cancellation (ANC) function. Usuários in different regions report malfunctions ranging from static noises to ambient sound leakage after minutes of use. Apple confirmed that it is aware of the complaints, but has not yet released a timeline for fully resolving the issue.
Consistent Sintomas reported by users
The problems show clear patterns among complaints. Ruídos static, hiss, and pops occur even without audio playback, especially when active cancellation or ambient sound mode is enabled. In many cases, only one of the headphones displays the symptom. Cancellation performance gradually decreases during use — it starts out effective for the first few seconds and then loses intensity, allowing ambient sounds to leak out as echoes or resonances.
Outro frequent symptom involves abnormal emphasis on low frequencies. Ruídos air conditioning, car, train and plane engines become more audible instead of being attenuated. Alguns users also report a feeling of pressure or clicking when putting on the headphones, as well as noise control crashes. The reports particularly focus on low-frequency sounds with specific characteristics, suggesting that the detection algorithm is not correctly differentiating between sounds that should be eliminated and sounds that should be preserved.
Possíveis technical causes of the problem
The ANC operating mechanism uses microphones to capture ambient sounds and emit sound waves with opposite phases to neutralize them. Quando this system fails, multiple factors may be involved. A first hypothesis points to a malfunction in the acoustic calibration process. If the earbud becomes misaligned in the ear or does not fit correctly, the microphones pick up unexpected sounds and the correction process malfunctions.
The build-up of wax or dirt on the external and internal microphones represents another real possibility. Esses two types of microphones work together to detect ambient noises and sounds inside the ear. Quando clogged, fail to capture properly, causing problems such as unrecognized or abnormally amplified noises.
Problemas software and firmware also deserve special attention. Relatos clusters after specific firmware updates, suggesting that tweaks to the ANC algorithm may be causing the observed changes. Incompatibilidades between versions of the connected device’s operating system and AirPods firmware may cause crashes and malfunctions.
The role of the H2 chip in instability
The H2 chip processes noise cancellation at a speed of 48 thousand times per second. Essa computational power offers effective reduction in the first moments, but there is a hypothesis that this very high speed optimization is causing malfunctions. Imediatamente after they are placed, preset cancel eliminates all frequencies. The internal microphone then recalculates the surrounding acoustic environment.
Nessa delicate step, the algorithm may overreact to certain constant noises, such as the low hum of the air conditioning. A slight change in the phase of the out-of-phase signal ends up causing noise to continue leaking, creating the reported leakage effect after a few seconds. Esse behavior suggests that this is not a simple defect, but rather enhanced real-time acoustic correction behavior that may be operating beyond its stability limits.
Soluções practices for affected users
Antes to consider repair or replacement, users should try resolution methods that have proven effective in online communities:
- Reinicie the Pro AirPods 3 by placing them in the case, closing the lid and waiting 30 seconds.
- Abra the cover and double-tap the front button three times until you see orange blinks followed by white.
- Reconecte to the Apple device and test if the problem is gone.
- Limpe carefully the microphone with a soft cloth or cotton swab.
- Remova the ear tips, rinse with water and dry completely.
- Verifique operating system version and update the AirPods Pro 3 to the latest firmware version.
If these steps do not resolve the problem, it is recommended that you take the product for diagnosis to an Apple Store or authorized service center. Produtos still under warranty may receive free repair or replacement. Proprietários with AppleCare+ are entitled to technical assistance at a reduced price. Alguns users obtained new units after consulting an Apple Store and properly documenting the issue.
Perspectivas future and follow-up
Apple has not yet announced a date for an update that specifically fixes this ANC issue. Affected Usuários monitor online communities for information about new firmware. The company’s technical support recommends starting with the basic troubleshooting steps before seeking in-person service. Especialistas in audio engineering point out that this type of problem, when concentrated after a specific update, often indicates a software solution rather than physical component failure. The expectation is that a future update will readjust the noise detection algorithm and resolve the reported instabilities.
