AKG K371 stuck on a firmware update is one of those moments that turns a quick software refresh into a frustrating waiting game. The progress bar freezes, the LED keeps blinking without changing pattern, or the app simply stops responding halfway through. Most people find that this happens for a handful of predictable reasons, and each one has a direct fix rather than a vague guess-and-check process.
Quick Takeaways
- A stuck firmware update on the AKG K371 is usually caused by low battery, Bluetooth interference, or an app glitch – not a hardware failure.
- Keeping the headphones charged and within close range of the paired device solves the update in most cases.
- Restarting the AKG Headphones app or the connected device often clears a frozen update screen.
- A full reinstall of the app is a safe last step before contacting AKG support.
- Sound or microphone issues after the update are usually resolved through the connected device’s audio settings.
Fix 1: Restart the Update With a Full Charge and Close Bluetooth Range
Firmware updates draw more power than regular playback, and a headset that drops below a certain battery threshold mid-update will often freeze rather than fail outright. Distance from the paired phone or laptop makes the same kind of difference, since Bluetooth firmware transfers need a stable, close-range connection to complete without dropouts.
- Step 1: Place the AKG K371 on its charging cable and let it reach a full charge before attempting the update again.
- Step 2: Move the paired phone or laptop within one to two feet of the headphones to reduce signal interference.
- Step 3: Turn off other Bluetooth accessories nearby, including smartwatches, speakers, or a second pair of earbuds.
- Step 4: Reopen the AKG Headphones app and start the firmware update again from the device page.
Pro Tip: Firmware transfers are sensitive to Wi-Fi routers and other 2.4GHz devices sitting close to the headphones. Moving away from a router for the duration of the update often prevents the freeze from happening a second time.
Fix 2: Force Close and Reopen the AKG Headphones App
A background app that has been running for hours is a common cause of a stalled update screen, especially on phones that aggressively manage battery usage. Force closing clears whatever process got stuck and gives the update a clean start.
- Step 1: Open the recent apps view on the phone and swipe the AKG Headphones app away completely.
- Step 2: Wait about ten seconds before relaunching the app, allowing background processes to fully clear.
- Step 3: Reconnect the K371 through Bluetooth settings if it does not automatically reappear in the app.
- Step 4: Navigate back to the firmware section and confirm the update starts downloading rather than resuming a stuck progress bar.
Fix 3: Restart Both the Headphones and the Connected Device
This step resolves the update far more often than it gets credit for. A frozen firmware screen is frequently a symptom of a memory or connection issue on the phone or laptop side, not the headphones themselves.
- Step 1: Power off the AKG K371 using the power switch on the ear cup and wait fifteen seconds.
- Step 2: Restart the connected phone, tablet, or laptop completely rather than just closing the app.
- Step 3: Power the headphones back on and confirm they show up as connected in the phone’s Bluetooth list.
- Step 4: Open the AKG Headphones app and check whether the firmware update prompt appears again on its own.
Fix 4: Reinstall the AKG Headphones App
Corrupted app data is a less common cause, but it does happen, particularly if the phone lost signal or lost power partway through a previous update attempt. A clean reinstall clears any leftover files that might be blocking the process.
- Step 1: Uninstall the AKG Headphones app from the phone or tablet entirely.
- Step 2: Restart the phone once the app has been removed.
- Step 3: Download the latest version of the app from the official app store listing.
- Step 4: Pair the K371 again and check the firmware section before attempting playback.
Pro Tip: Reinstalling the app does not erase anything stored on the headphones themselves – gesture controls, EQ presets, and pairing history on the K371 stay intact since they live on the device, not the app.
Fix 5: Update Through a Different Device or Reset the Bluetooth Connection
If the update still refuses to move forward on the original phone, switching to a second phone or tablet isolates whether the issue is with the headphones or with that specific device’s Bluetooth stack. This is also the point where re-pairing the headphones from scratch on a Windows laptop tends to clear connection-level glitches that block the update from finishing.
- Step 1: Remove the AKG K371 from the Bluetooth settings on the original device entirely, not just disconnect it.
- Step 2: Install the AKG Headphones app on a second phone or a laptop if one is available.
- Step 3: Pair the headphones fresh and attempt the firmware update from that device.
- Step 4: Once the update completes, return to the original device and pair again as normal.
Tips for a Smooth AKG K371 Firmware Update
A few habits make future updates far less likely to freeze in the first place. None of these take more than a minute, and together they cut down on almost every cause of a stuck update.
- Update during a period without other demanding Bluetooth or Wi-Fi activity on the same network.
- Keep the AKG Headphones app updated to its latest version before starting a firmware download.
- Avoid using the headphones for calls or playback while an update is actively running.
- Check available storage on the phone, since some update packages are cached locally before transfer.
Common Problems After a Failed or Stuck Firmware Update
No Sound After the Update Finishes
This usually points to the connected device defaulting to a different playback source rather than a problem with the headphones. Checking and adjusting the audio output settings on Windows 11 to confirm the K371 is selected as the active playback device resolves this in most cases.
Microphone Not Working Post-Update
A firmware update can occasionally reset which input device Windows treats as default. Working through steps for resolving microphone detection problems on Windows 11 usually gets the built-in mic recognized again without needing to redo the update.
Headphones Show as Connected but Produce No Audio
This is often a leftover audio driver conflict rather than a firmware issue. Running through a full audio reset clears cached settings that sometimes linger after an update – the process for resetting audio settings on Windows 11 covers this in detail.
Repeated Disconnects Right After Updating
A fresh firmware version occasionally needs the pairing profile rebuilt rather than just reconnected. Removing the device and pairing again, as covered in the Bluetooth re-pairing steps above, is the most reliable fix here.
Frequently Asked Questions
Why is the AKG K371 stuck on a firmware update?
The most common causes are low battery during the transfer, Bluetooth interference from nearby devices, or a background glitch in the AKG Headphones app. Hardware failure is rare and should only be considered after the standard fixes above have been tried.
How long should an AKG K371 firmware update normally take?
Most updates finish within five to ten minutes on a stable connection. If the progress bar has not moved for over fifteen minutes, treat it as stuck and work through the restart steps rather than waiting longer.
Is it safe to turn off the AKG K371 during a stuck update?
Yes, as long as the update screen has genuinely frozen rather than actively transferring data. Turning the headphones off mid-transfer is the standard first step recommended for most Bluetooth firmware updates that stall.
Does the AKG K371 need Wi-Fi to complete a firmware update?
No. The update downloads through the phone’s internet connection first, then transfers to the headphones over Bluetooth. A weak Wi-Fi or mobile signal on the phone can still slow down the initial download step, though.
Can a firmware update be restarted from zero after freezing?
Yes. Restarting both the headphones and the connected app is designed to safely restart the process. The headphones will simply repeat the update from the beginning rather than resuming from a corrupted midpoint.
What if the AKG K371 will not power on after a failed update?
Leave the headphones on the charging cable for at least thirty minutes, since some units draw down significantly during a failed transfer. If they still do not power on afterward, contacting AKG support directly is the safest next step.
Does reinstalling the AKG Headphones app delete headphone settings?
No. Reinstalling the app only removes the app’s local data on the phone. Gesture settings, sound presets, and pairing memory saved on the K371 itself remain untouched.
Why does the AKG K371 disconnect right after a firmware update?
A new firmware version sometimes requires the Bluetooth pairing profile to be rebuilt. Removing the device from Bluetooth settings and pairing fresh usually resolves this within a minute.
Can the firmware update be done from a computer instead of a phone?
Yes, updating through the app on a laptop works the same way as on a phone, and switching devices is a useful troubleshooting step if one device’s Bluetooth stack keeps causing the update to freeze.
Who should be contacted if the update still will not complete?
AKG’s official support channel through Harman should be the next step once charging, restarting, and reinstalling the app have all been tried without success. Persistent failure across multiple devices usually points to a hardware issue that needs direct support.
