TL;DR: USB-C AirPods Pro support lossless audio with the upcoming Vision Pro headset due to the 5GHz band support in their H2 chip. The previous version only had 2.4GHz.

    According to Wikipedia the theoretical max bandwidth on the 2.4GHz bandwidth is 706,25 kbit/s downstream.

    I don’t have data from Apple, but Qualcomms lossless Bluetooth audio transmits up to 1Mb/s.

    So, a three minute internet search supports rather apples story than yours.

      Wow. Not only incorrect, but incorrect in the worst way by fucking up maths by a factor of a thousand!

      Yeah wiki also says.

      Bluetooth 2.0 already supports 3mbps or (2.1mbps real world)

      The bit rate of EDR is 3 Mbit/s, although the maximum data transfer rate (allowing for inter-packet time and acknowledgements) is 2.1 Mbit/s.

      BT5 expands on the Low Energy specifications to allow 2mbps burst.

      Bluetooth 5 provides, for BLE, options that can double the speed (2 Mbit/s burst) at the expense of range, or provide up to four times the range at the expense of data rate.

      Also 802.11n already runs at 54mbps for a 20mhz wide channel.
