LG OLED 65-inch TVs support wireless headphones via Bluetooth, but users often experience
audio latency (lip-sync lag) because the TVs typically default to the high-latency
SBC codec. This delay is inherent to standard Bluetooth transmission and can be noticeable during gaming or fast-paced content.
To mitigate or eliminate this delay, consider the following solutions:
- Enable Audio Sync Settings: Navigate to Settings > Sound > Advanced Settings and adjust the Audio Sync or Lip Sync slider to manually align the audio with the video.
- Use aptX Low Latency (aptX LL): If both the TV and headphones support aptX LL, latency can drop below 40ms. Many newer LG OLEDs (like the C1 and B4 series) support aptX, but you must verify your specific model's codec support in the manual or settings.
- Switch to Wired Headphones: Using a 3.5mm audio jack or an optical-to-headphone adapter provides a zero-latency connection, which is the most reliable method for gaming or critical viewing.
- Use an External Bluetooth Transmitter: Plugging an aptX Low Latency transmitter (e.g., from Avantree or 1Mii) into the TV’s optical output or headphone jack can bypass the TV’s internal Bluetooth limitations, offering significantly lower latency than native pairing.
- Enable Simultaneous Audio Output: For those who need both TV speakers and headphones active, enable Simultaneous Audio Output in the sound settings to avoid muting the TV speakers when headphones are connected.
Note: Some apps (like YouTube) may exhibit higher latency than others due to different audio processing pipelines. Regularly updating the TV’s
firmware can also improve Bluetooth performance and add support for newer codecs.
