Common Issues and Solutions

Sound Problems: No Sound, Distorted Audio, or Low Volume

Let's kick things off with the most fundamental issue: sound problems. There's nothing worse than putting on your headphones, ready to enjoy your favorite music, only to be met with silence or distorted audio. Don't worry, in many cases, fixing these sound issues is a piece of cake. First things first, check the basics. Ensure that your JBL Live 670NC headphones are turned on and connected to your device. Sometimes the simplest solution is the one that works! Make sure the volume on both your headphones and your connected device (phone, laptop, etc.) is turned up. It sounds obvious, but you'd be surprised how often this is the root cause. If the volume is fine, and you still hear nothing, make sure your audio source isn’t muted or paused. Maybe you accidentally hit the mute button on your phone or computer. Check the audio output settings on your device to make sure your JBL Live 670NC is selected as the output device. Sometimes your device might switch the output to something else (like your laptop's built-in speakers). Also, check the headphone's physical state. A blocked headphone grille can reduce the sound. Use a soft brush to gently clean any debris or dust from the earcups. If the sound is distorted, try adjusting the EQ settings on your device or in the JBL app. Sometimes, a poorly configured EQ can cause the audio to sound off. Test different presets or create a custom EQ to find the best sound for your ears.

Another thing is the firmware. Outdated firmware can cause various audio glitches. Make sure your headphones' firmware is up-to-date. Connect your headphones to the JBL app (if you have it installed) and check for any available firmware updates. Outdated firmware can lead to all sorts of audio-related problems. In the case where you have a specific problem with one type of audio: a particular app or file type, the issue is not with the headphones, but likely with the source. Check the audio file to see if it's corrupted or if there's any problem during playback. Try playing a different audio file or using a different app to see if the problem persists. This will help you identify whether the issue lies with the headphones or the audio source. If all else fails, a simple reset can work wonders. Turn off your headphones, then turn them back on. This resets the internal system and often resolves minor software glitches.

Bluetooth Connection Problems: Pairing Issues and Disconnections

Bluetooth connectivity issues can be frustrating, especially when you're eager to listen to your music. Let's dive into fixing those annoying pairing issues and disconnections on your JBL Live 670NC headphones. The first step in resolving Bluetooth issues is, as usual, to reboot. Restart your headphones and the device you’re trying to connect them to. This simple action often clears up minor Bluetooth glitches. Ensure your headphones are in pairing mode. Typically, this involves pressing and holding the power button until the LED light blinks, indicating that the headphones are ready to connect. Ensure your device’s Bluetooth is enabled and searching for new devices. Go to your device's Bluetooth settings and see if your JBL Live 670NC appears in the list of available devices. If your headphones are visible, tap on them to start the pairing process. If the headphones aren't showing up, try restarting the Bluetooth on your device or clearing your device’s Bluetooth cache.

Make sure your headphones are not already connected to another device. If they are, disconnect them from that device first before trying to pair them with a new one. Bluetooth can sometimes get confused, especially if the headphones are trying to connect to multiple devices. Check for interference. Bluetooth signals can be affected by other electronic devices, such as Wi-Fi routers, microwaves, and other Bluetooth devices. Keep your headphones and the device you're connecting to away from these sources of interference. Distance can also be an issue. Make sure your headphones and your device are within the recommended Bluetooth range, which is typically around 33 feet (10 meters). Bluetooth signals can weaken over distance, so the closer, the better. Try forgetting and then re-pairing the device. On your device, go to the Bluetooth settings, find your JBL Live 670NC, and choose the option to “forget” or “unpair” the device. Then, put your headphones back into pairing mode and try pairing them again. If all else fails, it might be a software issue. Check for firmware updates for your JBL Live 670NC headphones via the JBL app. Outdated firmware can sometimes cause Bluetooth connectivity problems. Also, make sure that the Bluetooth drivers on your connecting device are up to date. Sometimes it’s the device, not the headphones, causing the problem.

Battery Problems: Quick Draining and Charging Issues

Battery life is crucial for any wireless headphones. Let's troubleshoot common battery problems you might experience with your JBL Live 670NC. If your headphones are draining very quickly, there are a few things to check. First of all, are you using features that consume a lot of battery? Noise cancellation (ANC) and Ambient Aware modes consume more power than regular listening. If you don't need these features, consider turning them off to conserve battery life. Make sure you're not listening at excessively high volumes. Higher volumes demand more power, and can shorten the battery life significantly. Also, check the operating temperature. Extreme temperatures (hot or cold) can affect battery performance. Avoid exposing your headphones to direct sunlight or freezing temperatures, as these can impact the battery.

Next, let’s check the charging issues. If your headphones aren't charging properly, the cable or the power source could be the culprit. Try using a different USB charging cable and power adapter. It’s possible the original cable is damaged, or the power adapter isn't working correctly. Make sure that the charging port on your headphones is clean and free of debris. Use a soft brush or compressed air to remove any dust or particles that might be preventing a good connection. Another thing you should check is the power source. Try plugging the headphones into a different USB port or wall outlet. Sometimes, a particular port or outlet may not provide enough power for charging. Also, try letting the headphones fully charge. Leave them plugged in for the entire charging cycle to make sure they get a full charge. A full charge will help you assess the battery's overall health. Finally, check for firmware updates via the JBL app. Sometimes, firmware updates can improve battery performance and address charging issues. If the battery is old or damaged, its performance will decline over time. In this case, you might need to contact JBL support for assistance.

Advanced Troubleshooting and Solutions

Hard Resetting Your JBL Live 670NC

Sometimes, a hard reset is needed when simple fixes don't cut it. A hard reset can often resolve more complex software glitches that can't be fixed with a simple power cycle. The exact steps for performing a hard reset can vary, so consult your user manual for the most accurate instructions. Typically, a hard reset will involve pressing and holding a specific combination of buttons on your headphones, often the power button and the volume up or down button. This will reset the headphones to their factory settings. Make sure to back up any custom settings or profiles that you want to keep, as a hard reset will erase these.

After performing the hard reset, try pairing your headphones with your device again and test their functionality. If you're still having issues, it could indicate a hardware problem or a more complex software issue. If this doesn’t work, move on to the next solution.

Updating the Firmware

Keeping the firmware of your JBL Live 670NC headphones up-to-date is a crucial step in maintaining their performance. Firmware updates often include bug fixes, performance improvements, and sometimes even new features. To update the firmware, you'll typically need to download the JBL app, which is available for both Android and iOS devices. Once the app is installed, connect your headphones to your device via Bluetooth. Open the JBL app, and it should automatically recognize your headphones. Look for a section in the app that deals with firmware updates. The exact location may vary depending on the app version, but it's often located in the settings menu or the device information section. The app will check for any available firmware updates for your headphones. If an update is available, follow the on-screen instructions to download and install it. This process may take a few minutes, so make sure your headphones are fully charged or connected to a power source.

When to Contact JBL Support

Knowing when to seek professional help is important. If you've exhausted all the troubleshooting steps, and your JBL Live 670NC headphones are still malfunctioning, it's time to contact JBL support.

Preventive Measures and Maintenance

Proper Care and Storage

To clean the earcups, you can gently wipe them with a slightly damp cloth. Avoid getting any moisture inside the headphone components. You can use a soft brush or compressed air to remove any dust or debris from the charging port and other crevices. Make sure to clean the mesh on the earcups regularly, as this can become blocked. Keeping the earcups mesh clean helps preserve sound quality and reduces the risk of sound distortion. Regularly inspect the headphones for any signs of damage. If you notice any cracks, tears, or loose parts, address them promptly to prevent further damage.
