Yes, you can use headphones with HDMI, but not directly. HDMI transmits both audio and video signals, and most headphones do not have an HDMI input. Instead, you can use an HDMI audio extractor or converter. This device connects to the HDMI source and splits the audio signal from the video, allowing you to connect headphones through a standard audio output like a 3.5mm jack or RCA. Here’s a basic setup:

1. Connect the HDMI source (e.g., a gaming console or Blu-ray player) to the HDMI input of the audio extractor.
2. Use another HDMI cable to connect the extractor’s HDMI output to the TV.
3. Connect your headphones to the extractor’s audio output using the appropriate cable or adapter.

This setup lets you receive audio through your headphones while the video signal is sent to your TV via HDMI. Remember, the specific type of audio extractor needed may depend on your headphones’ input requirements and the audio formats you wish to support.

This will depend on whether or not your TV supports using multiple audio outputs simultaneously. This is generally not the case, but you can check your TV’s manual or contact the manufacturer for confirmation.

If the sound isn’t coming through your headphones when connected to the TV, consider the following troubleshooting tips:

1. Check the Headphone Connection: Ensure the headphones are properly connected to the TV or the external device like a Bluetooth transmitter.
2. Volume Settings: Verify that the volume is turned up on the TV and your headphones.
3. Audio Output Settings: Check if the TV’s audio output is correctly set to your headphones. Some TVs require you to manually switch the audio output to headphones.
4. Compatibility and Pairing: Ensure the headphones are compatible with your TV and, if using Bluetooth, that they are correctly paired.
5. Battery and Charge: If using wireless headphones, check that they’re charged and powered on.
