Hi there. Thank you for sharing your inquiry about the 43UA7700AUA TV and its audio capabilities. We understand your question and are happy to confirm that the LG 43UA7700AUA 4K Smart TV does support connecting an external audio device via Bluetooth. This means your mother can absolutely connect Bluetooth headphones, earbuds, or a hearing assistance device to the TV for private, wireless listening, which is a wonderful feature for personal use. For the 43UA7700AUA, you would access the settings to enable this connection. Here is the basic troubleshooting step to get started with the connection process, as you inquired about it: Put her Bluetooth listening device (like headphones) into pairing mode according to the device's manufacturer instructions. On the TV, press the Settings button on the Magic Remote. Navigate to Sound → Sound Out. Select Use Wireless Speaker → Bluetooth Device. The TV will search for nearby devices. Once her headphones appear in the list of Connectable Devices, select them to complete the pairing. This process will allow the sound to be outputted directly to her private Bluetooth device. Furthermore, LG Smart TVs often have an accessibility feature that allows the sound to be played through both the internal TV speakers and the Bluetooth device simultaneously. This is especially helpful for households where others might be watching with her. https://www.bestbuy.com/product/lg-43-class-ua77-series-led-ai-4k-uhd-smart-webos-tv-2025/JJ8VPZT652 If you have any further questions about this feature or need more specific details on setting up the simultaneous sound, please send us a private message on Social Media @LGUSSupport, and our team will be more than happy to assist you. —Renzo
