You could be right. Unless the H3 chip allows lossless I’m not sure what it could bring.If the AirPods Max v2 get released this year I imagine they'll get USB-C and H2 chip as their most obvious updates but the H2 chip is going to be two years old by then. Are Apple gonna put the H2 chip in their most premium headphones? It's rumoured the H3 chip is coming in 2025. If thats the case Apple might not release the AirPods Max v2 until 2025 and give them the H3.
It's rumoured that the AirPods Max v2 are gonna be a small, incremental update but I do wonder whether Apple wants a much more comprehensive update since Sonos has entered the headphone market and Apple intends to blow the competition out of the water.
My guess is we will see v2 in September/October with H2 and USB-C.
