JBL Tune 510BT Troubleshooting

Released in early 2021, the JBL Tune 510BT is a set of wireless, Bluetooth, over-the-ear headphones.

The headphones will not power on.

Charging cables can often fail over time, so test if the cable and adapter are functioning. The easiest way is to plug in another device that accepts the USB-C from the charging cable. If a device is unavailable, use a multimeter to test the voltage. If the charging cable or power adapter is the issue, replace them with another of the exact device specifications.

The issue might be the outlet to which the power adapter is connected. This issue can happen for many reasons, but to check if this is the issue, move the power adapter to another outlet on a different circuit.

At times, power cables or where they connect can become less secure. It is possible that the charging cable is not fully plugged in. Check the connection and firmly push the charging cable into place. The LED near the power button should turn red when the cable is connected correctly.

The easiest solution for sticking buttons is repeatedly pressing the button and seeing if you can loosen it. If the button continues to be stuck, use a flashlight to examine the buttons and check for any small debris or dust that has gathered around the button. Using a toothpick or pin, clean the area around the buttons, dislodging any material that may have gathered there. Once you have removed all the dust, add a small amount of lubricant, WD-40, rubbing alcohol, or any other preferred oil to the button. Repeatedly press the button 10-20 times to spread the lubricant evenly. Do not overuse lubricant on the button, as it may cause more damage. If this does not resolve the issue, the buttons may need to be repaired or replaced. Consult this guide to learn more.

The headphones will not connect to the customer's desired device.

If your headphones are not connecting to your device, there are a few common issues. It is possible that the headphones are not turned on. Confirm the headphones are charged and try again. Another issue might be that the headphones are out of range and can't be found by your device. Bring the headphones closer to your device and confirm both are in pairing mode. This is indicated by the power button's blinking blue light on the headphones. Make sure the headphones are not connected to another device.

When working correctly, Bluetooth can significantly improve the user experience; however, the connection doesn't always work. Luckily, the solution can be straightforward. First, restart the Bluetooth connection on your device by switching Bluetooth off, waiting for 10 seconds, and then switching Bluetooth on again. Give the device another 10 seconds. If the headphones don't show up on devices ready to be paired, try these additional steps to ensure a connection with your device.

Apple devices

The first step is to "Forget" the previously paired connection and try again. On your device, open up the settings app and click on Bluetooth. Next, find the headphone name (by default, the headphones are named JBL TUNE510BT) and press the blue i icon on the right of the headphone name. Select "Forget This Device" and confirm by selecting the red "Forget Device" at the bottom of your screen. Once the device has forgotten the headphones, turn the headphones off and on again. When the headphones turn on, you should see them pop up as an option for a potential device to be paired with. Select the headphones and wait for them to pair to your device. Your headphones and device should now be paired together.

Samsung devices

Open up the settings app on your device, click on connections, and then Bluetooth. Next, find the headphone's name (by default, the headphones are named JBL TUNE510BT), press the gear icon on the right of the headphone's name, and select the "unpair device" button on the bottom right of your screen. Select "Unpair Device" and confirm by selecting the red "Unpair Device" at the bottom of your screen. Once the device has forgotten the headphones, turn the headphones off and on again. When the headphones turn on, you should see them pop up as an option for a potential device to be paired. Select the headphones and wait for them to pair to your device. Your headphones and device should now be paired.

Open the settings and click the Devices section. Once there, look for the headphones in the list of connected devices (by default, the headphones are named JBL TUNE510BT). Click on them once and select remove. Once removed, power on the device and put it in pairing mode. Click the option at the top that says "Add Bluetooth or other device." A menu will pop up with multiple options. Click on the top one that says Bluetooth and select the headphones. Your headphones and PC should now be paired.

The buttons can become stuck, loose, or completely unresponsive.

If the headphones are used on another device, occasionally, they can connect to another device rather than the desired one. If this is the case, the problem lies with the button and the device's connection. To check this, refer to the "The Device's Bluetooth Won't Pair" section above. Once the headphones are connected to the desired device, test the buttons again to see if they are responsive now.

If the buttons have not been used in a while, they tend to get stiff and hard to press. A simple way to solve this problem is to vary how you press the button down. First, try to press the button down from different angles. For example, if the button has trouble being pushed straight down, start from the top and push towards the bottom. Next, press the button from the right side to the left. If the button is still stuck, increase the amount of pressure you are applying on the button. Repeat this process until the button is loosened enough to be pressed easily and freely.

If the buttons are damaged beyond a simple fix, it may be time to replace them. This guide provides more instructions on how to replace the buttons on your headphones.

The light is not glowing, is dull, or is physically missing.

The battery is too low to power the light. Confirm that the charging cable and power adapter are in working order and plug them into the device. When properly charging, the LED emits a red light next to the power button. If you can't get the device to charge, refer to the "Device Won't Turn on" troubleshooting guide.

The light comes from a translucent component seated in a rubber housing. One of these components may be either damaged or simply unseated. Remove the right ear muff on the device and locate the three 3mm Phillips head screws. Loosen and remove the speaker from its housing. Confirm the location and condition of the two components. If it has simply become dislodged, replace it back in its proper position next to the power button. Insert the exposed translucent piece through the hole in the headphones casing. Be sure to seat the rubber casing. Replace the speaker, replace the screws and tighten them and reattach the ear muffs. If charged, a blue or white light should appear when powered back on.

If none of these options solve the issue, you may have to repair the LED. For more information, refer to the repair guide here.

The padding around the speakers is no longer functional or comfortable to use.

Refer to the earmuff repair guide here.

The audio integrity of the speakers is no longer at the desired level.

Leave the device in a bag of rice overnight. If this does not resolve the issue, refer to the speaker repair guide.

For any other damage, refer to the speaker repair and replacement guide here.

The hinges above the speakers that enable the earmuffs to fold and unfold have become weak or damaged.

Unfortunately, JBL uses both proprietary parts and has designed the hinges in a way that, once assembled, cannot be taken apart without extensive effort and damage to other parts of the device.
