Why is the sound not coming through on my Jabra headset?

Check Audio Settings

One of the most common reasons for no audio coming through a Bluetooth headset is the volume being muted or set too low. Here are some things to check:

Confirm the volume on the Jabra headset itself is turned up. There are volume up/down buttons directly on the headset. Press these while audio is playing to see if adjusting the volume results in audio coming through.

Also check the volume on the connected smartphone, tablet, or computer. Make sure the volume is turned up on the device that is paired with the Jabra headset. Sometimes the device volume gets turned down which prevents audio from making it to the headset.

Try adjusting the volume controls on both the headset and connected device while audio is playing. The volumes may need to be changed while playing audio to actually take effect. Check if audio starts coming through after adjusting the volume levels.

Check Bluetooth Pairing

One of the most common reasons for a Jabra headset not producing sound is an issue with Bluetooth pairing between the headset and your device. Confirm that the Jabra headset is actively paired and connected to your phone, tablet, or computer by checking the Bluetooth settings on your device. You should see the Jabra headset listed as a paired device. If you don’t see it listed, you’ll need to pair the headset again:

1. Put your Jabra headset in pairing mode – this usually involves pressing and holding the multi-function button until the LED flashes blue. Consult your headset manual for exact instructions.

2. Open the Bluetooth settings on your device and select the option to add or pair a new device. Your Jabra headset name should show up in the list of available devices.

3. Select your Jabra headset to pair it with your device. Confirm pairing on both your device and headset if required.

Once paired, check if audio now comes through the Jabra headset by playing media on your device. If you are still not getting any audio, try unpairing the headset completely, powering it off and then pairing again from scratch. This reconnects and re-syncs the Bluetooth connection which often resolves many audio issues.

Update Firmware

One common reason for audio issues with Jabra headsets is outdated firmware. Jabra regularly releases firmware updates to fix bugs and improve performance. Make sure your headset is running the latest firmware version.

You can check for and install firmware updates using the Jabra Direct software. Jabra Direct will automatically detect your headset model and download any available updates when you connect the headset to your computer. Follow the on-screen instructions to update the firmware.

If auto-update is not working, you can manually download and install the latest firmware from the Jabra support site. Go to https://www.jabra.com/supportpages/jabra-direct and find the product page for your specific headset model. Under the Firmware section, download the latest firmware file. Then use Jabra Direct to manually select and install the downloaded firmware file.

Updating to the newest firmware can resolve a wide range of technical issues, including no audio. It ensures you have all the latest improvements and optimizations from Jabra.

Try Resetting the Headset

Resetting your Jabra headset to factory default settings can often resolve issues with no audio output. This clears out any faulty settings and resets the headset’s audio system. According to Jabra’s support site, start by putting your headset in pairing mode – this varies by model but often involves holding the power button for 5-10 seconds until the LED flashes blue and red. Next, on your phone, tablet or computer, find the headset in your Bluetooth devices and select “Forget Device” to unpair it. Finally, pair your headset to your device again as if it were new. This reconnects the audio drivers from scratch which should enable sound. If you still have no audio after resetting, contact Jabra’s support team for troubleshooting help before assuming hardware failure.

Check for Obstructions

One common reason for no sound coming through a Bluetooth headset is obstructions in the way of the microphone or speaker. Ensure that nothing is blocking the microphone opening or speaker grille on your Jabra headset.

First, inspect the microphone opening on the headset to make sure it is not covered by debris, dust, lint, or any other particles. Use a canned air duster to gently blow away any visible obstructions. Also check that the small noise-canceling microphone openings on the headset are not blocked. Even a small piece of lint can muffle the microphone.

Next, check the speaker grilles and make sure they are also free of any dust or debris that could be blocking sound. Use a soft brush or cloth to gently clean the speaker grilles if needed. Be very careful not to push any debris further into the headset.

Finally, check that you do not have any hair, scarves, hoodies, or other items unintentionally covering the Jabra headset while in use. Make sure the microphone and speakers have a clear line to your mouth and ears.

With the headset free of obstructions, the microphone and speakers should function properly. If you still have no audio after ensuring nothing is blocking the headset, move on to troubleshooting other potential issues.

Test on Another Device

One way to determine if the issue is with your Jabra headset or with your phone/tablet/computer is to pair the headset with another device and test it. Pair the headset with another smartphone, tablet, laptop, or desktop computer that supports Bluetooth audio. Make sure Bluetooth is enabled on the other test device.

Go through the pairing process to connect your Jabra headset to the new device. Then try playing audio and see if you can hear sound coming through the headset now. If the headset works fine when paired with another device, then the problem likely lies with the settings or Bluetooth connectivity of your original phone/tablet/computer.

However, if you still cannot get any audio when paired to multiple devices, then there may be an issue with the Jabra headset itself. Isolating the problem to a specific device versus the headset can help narrow down where the underlying issue originates.

Disable Battery Saving Mode

Battery saving modes on your headset, computer, or phone can sometimes interfere with Bluetooth connectivity. These modes try to conserve power by disabling certain features, including Bluetooth. This can cause intermittent audio cutouts or losing connection entirely.

To prevent battery saving modes from disrupting your Jabra headset, disable these settings:

On Windows 10 or 11, go to Settings > Devices > Bluetooth and disable “Allow Bluetooth devices to wake this computer” and “Allow this device to wake the computer.”
In Device Manager, disable “Allow the computer to turn off this device to save power” for your Bluetooth driver. [1]

On Android, disable Battery Optimization or settings like “Suspend execution” for the Jabra app and Bluetooth system app.

With battery saving modes disabled for Bluetooth, your Jabra headset should maintain a stable connection.

Forget and Re-pair the Jabra Headset

If your Jabra headset is connected to your device via Bluetooth but still has no sound, forgetting the headset and re-pairing it from scratch may resolve the issue. Here are the steps to try:

Go to the Bluetooth settings on your device and find the Jabra headset in the list of paired devices.
Select the option to “Unpair”, “Forget”, or “Remove device” to disconnect the headset.

On the Jabra headset, press and hold the power button for 15-20 seconds to reset it.
Put the Jabra headset back into pairing mode by holding down the call button until you hear “pairing” or the LED flashes blue.
Go back to your device’s Bluetooth settings and select to add new device. Then choose the Jabra headset to reconnect it.

Test if the audio issue has been resolved by playing music or a call.

Forgetting a Bluetooth device and repairing removes any faulty settings that may be causing connection issues (source). Re-pairing forces both devices to re-establish the Bluetooth connection from default settings. So this can often fix audio problems like having “Bluetooth connected but no sound”.

Get a Replacement

Locate your purchase receipt to verify the warranty status and date of purchase.

Bring your headset to the original place of purchase and provide your receipt.
The retailer can process a warranty claim with Jabra to supply you with a replacement headset if yours qualifies based on the purchase date.

You can also try contacting Jabra support directly with your serial number and purchase details to see if they can assist with a warranty replacement. But going through the original retailer is often faster.
