If your Beats Studio Pro doesn't feel like it's blocking out the world the way it used to, don't assume the hardware is shot. Most ANC problems on these headphones come down to a broken seal, a mode mix-up, or outdated firmware. Let's run through the fixes that actually work.
The first thing to check is whether the earcups are sitting flush against your head. Over-ear ANC depends on a complete physical seal around your ears. If your hair is bunched under the band, or if you're wearing glasses with thick frames, air leaks in and the active cancellation can't compensate. Adjust the headband so the cups clamp evenly and press your glasses arms flat against your temples.
Make sure ANC is actually on
Sounds obvious, but I've spent five minutes troubleshooting before realizing I'd accidentally switched to Transparency mode. On the Studio Pro, press the b button on the left earcup to cycle through ANC, Transparency, and off. Listen for the voice prompt confirming "Active Noise Cancellation." If you don't hear it, keep pressing until you do.
On an iPhone, you can also check the Control Center by long-pressing the volume slider and verifying the card says "Noise Cancellation." On Android, open the Beats app and check the noise control setting at the top of the device screen.
Update the firmware through the Beats app
Apple pushed several firmware updates after the 2023 release that tweaked ANC processing. The most recent one fixed a bug where the headphones would randomly drop out of full ANC. On Android, open the Beats app and let it sync. If a firmware update is available, you'll see a prompt, tap it and keep the headphones within a few feet of your phone for the 10 15 minute update. On iOS, updates happen automatically when the headphones are connected and charging, but you can force a check by going to Settings > Bluetooth, tapping the info icon next to Studio Pro, and scrolling to "About."
One note: lossless audio over USB-C requires Beats app version 1.6 or later. If you're using a wired USB-C connection and getting poor ANC, update the app first, it also handles the ANC driver calibration for that mode.
Turn off Spatial Audio for stereo tracks
Beats Studio Pro supports Personalized Spatial Audio with dynamic head tracking, but it can make regular music sound thin or hollow, which some people mistake for weak ANC. The noise cancellation itself is still working, the audio processing is just messing with the soundstage. On iPhone, go to Control Center, long-press the volume slider, tap Spatial Audio, and set it to "Off." On Android, disable it in the Beats app under the Spatial Audio setting. Once it's off, see if the ANC feels more substantial.
Reset the headphones
If the software side checks out, a full reset clears out any stale state in the ANC controller. Press and hold the system button (the power button on the right earcup) for 10 seconds. You'll see the Fuel Gauge LEDs flash white, then a single red LED flashes in a repeating sequence three times. Once the lights stop, the headphones reset and automatically power back on. You'll need to re-pair them to your phone, but this wipes any corruption that might have been messing with the noise cancellation logic.
After the reset, press the b button to re-enable ANC and test it with some consistent background noise (like a fan or HVAC).
Clean the microphones and charging port
The Studio Pro uses external microphones to pick up ambient noise and generate the opposing sound waves. If those mic openings are blocked by dust, sweat, or lint, the ANC processor gets bad data and cancels poorly. Check the tiny grilles on each earcup, there are small holes near the edges where the mics live. Use a dry, soft brush (a clean toothbrush works) to gently sweep across them. Don't poke with anything sharp.
Also check the USB-C charging port. The known issues list specifically calls out charging port debris after sweat exposure. Even if you aren't using USB-C for audio, a dirty port can cause erratic behavior that affects the whole power/noise system. Compressed air carefully aimed at the port works, or a wooden toothpick to gently dislodge gunk.
Consider Android-specific quirks
If you're using the Studio Pro with an Android phone, know that auto-pause (the accelerometer-based play/pause when you remove the headphones) is notoriously unreliable on Android. When it misbehaves, it can also interfere with ANC mode switching because the headphones get confused about whether they're being worn. Turn off auto-pause in the Beats app under Wear Controls > Auto Play/Pause if it's causing issues. You won't lose any ANC functionality by disabling it, and the headphones will stop second-guessing their active state.
Also, Find My only works on iOS, so don't count on it to locate your headphones if they go missing while paired to Android, that's normal, not a defect.
One last thing: ANC is great at canceling steady low-frequency noise (airplane hum, fans, traffic) but less effective at blocking sudden sounds like voices or keyboard clicks. If your expectations are set against unpredictable noise, the Studio Pro will feel weaker no matter what you do. But if the constant background drone has started bleeding through, one of the steps above should bring the silence back.
