Q1571473619021 , via OnePlus Community App , Nov 20, 2019 : I connected my Sony xb450 headphone through mi Bluetooth recievers. I felt sound was very less. So I have below questions : 1. Which audio codecs are supported by OnePlus tv Bluetooth ? aptxhd, sbc etc? 2. does OnePlus tv support Dolby Atmos for headphones? 3. If I buy Bluetooth DAC, will the audio performance increase? I am planning to buy FiiO BTR3 Hifi Bluetooth Reciever or FiiO BTR1K hifi heaphone AMP/DAC Bluetooth reciever. thanks advance.
