fer0nApple Explains Why Only USB-C AirPods Pro Support Lossless Audio With Vision Pro
deegeeseTL;DR There is enough bandwidth in 2.4GHz, but fuck you consumer, buy more AirPods.
redballooonAccording to Wikipedia the theoretical max bandwidth on the 2.4kHz 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.
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.
