For best results, connect via the optical cable and set your TV’s audio output format to PCM or stereo. This minimizes delays and improves overall viewing experience[1][7].",{"question":158,"answer":159},"Can I connect a second pair of headphones to the avantree Wireless Headphone Transmitter Set BTHT-4189?","Yes, the avantree BTHT-4189 supports pairing with a second set of headphones simultaneously.
