I bought this product 4 months ago to plug into my Yamaha amplifier so that I could watch TV (BDP player and various streaming services all feed in to the amp) using a wireless headphone. Some research indicated that this required Bluetooth with ‘Low Latency’ to avoid dialog and picture being out of sync.
