Hi there, Thank you for choosing Sony! We appreciate your inquiry and are happy to assist. The ability to use your WH1000XM5 headphones while simultaneously outputting audio through your TV’s built-in speakers depends on your television’s specific model and audio settings. For guidance, please refer to this video on how to enable sound from both your TV speakers and audio devices simultaneously (dual audio output): https://www.sony.com/electronics/support/articles/00049501 If you own a Sony BRAVIA TV, we recommend contacting our support team with your model number so we can confirm compatibility with dual audio output functionality.
