Different wireless headphones have varying instructions for updating their software. Refer to your headset’s user manual for directions on updating it to the latest firmware version. If using a laptop, search for the latest Bluetooth drivers online to troubleshoot connection problems and fix sound delays. 

Unsynchronized Audio

Sometimes, you might experience sound delays on your Bluetooth headphones because the audio and video on your smart device are out of sync. Unsynchronized audio is a common problem with TVs. It could be broadcast issues or a bad connection causing sound delays on your headset.

Fortunately, there are several ways to fix audio-sync issues. Here are a few troubleshooting tips:

  • Power reset your TV by unplugging it from the wall outlet and then plugging it back in after 3 minutes.
  • If your TV support it, enable the audio sync feature in the audio settings menu.
  • Reset the Bluetooth connection between your smart device and Bluetooth headphones.

Faulty Bluetooth Receiver or Transmitter

Bluetooth devices have a built-in adapter that sends or receives wireless signals from compatible devices. Sound lags might occur if this Bluetooth adapter is defective. You’ll have to check if hardware problems are causing the delays by testing your headphones and the source device.

The quickest way to test your Bluetooth headphones is to connect them to a different source device. If the headset works without sound delays when connected to another device, the previous audio output device could be faulty. If the audio lags persist when connected to various devices, your headphones could be defective.

The only solution to this problem is to repair or replace the device with a faulty Bluetooth adapter. Sometimes it could be cheaper to buy a new pair of Bluetooth headphones.

Audio Enhancements

Some smartphones and Windows computers support audio enhancements to boost the sound quality of your Bluetooth headphones. However, these enhancements can be counterproductive, leading to unnecessary audio delays and interruptions. 

Instead of enhancing the audio quality of your headphones, this feature can distort the sound and cause latency issues. Disabling audio enhancements can help resolve the problem.

Follow these steps to disable audio enhancements on your Windows PC:

  • Go to Start.
  • Click Settings.
  • Select System.
  • Click Sound.
  • Go to the Output section.
  • Select Headphones.
  • Under Enhance audio, click Advanced.
  • Go to the Properties window and click the Enhancement tab.
  • Click the Disable all enhancements checkbox.
