Hi kolart. Bluetooth technology does have audio latency. For example, Bluetooth headphones and earbuds experience at least 32ms of audio latency. But that's only in ideal circumstances. You're more likely to run into a 100-300ms delay, especially while using true wireless earbuds. The LG NanoCell 90 Series 2020 55 inch Class 4K Smart UHD NanoCell TV w/ AI ThinQ® (54.6'' Diag), Model # 55NANO90UNA is a Bluetooth (ver. 5.0) enabled TV which is the current standard for wireless audio transmission. It processes data faster than previous iterations of Bluetooth—effectively generating higher quality audio with shorter delay times. But Bluetooth 5.0 doesn't totally mask the latency of wireless audio. It also supports apt-X which utilizes the Bluetooth 5.0 technology for audios of low latency. The end-to-end delay is provided by this technology when the transmission is being done via Bluetooth, not higher than 32 ms. The delays in the normal stereo Bluetooth can vary greatly and are dependent on the implementation and buffering of the system. As a matter of fact, +40 ms to -60 ms is the recommended delay in synchronization of audio and video in broadcast television. The WiSA wireless audio specification allows for up to eight (8) channels of uncompressed 24-bit, 96KHz audio with an extremely low 5.2ms of latency ( at 48kHZ and 2.6 ms at 96kHZ) and less than 1 microsecond of synchronization between speakers for a perfect audio experience. You cannot use WiSA, Optical and HDMI simultaneously and when streaming audio to Bluetooth Headphones or Speakers, the TV's internal speakers and audio outputs are disabled...^IFV
