The AirPods Max digitize wired input with a 48kHz sample rate for processing, so even using the ($29!) cable won't deliver any sort of benefit from this.

- sethhochberg 5y ago"Lossless" just means there is no (lossy perceptual) compression involved. You could absolutely have a 48khz lossless signal, or even 44.1khz if you were dealing with a CD rip, and it would likely still measure better than the lossy equivalent audio sent over AAC or aptX via Bluetooth. I'll skip the whole debate about how good perceptual lossy encodings actually are these days and whether any person could reasonably expect to hear that measured difference, but just wanted to clarify that the sample rate of the headphones' built-in ADC shouldn't be conflated with the lossless codec.
- bydo 5y agoWell, yeah. There are two parts to this, the lossless compression and the "HiFi" sample rate (it goes up to 24-bit 192kHz). I was just pointing out that you don't get the high sample rate even over analog. I haven't seen anywhere whether AirPods can do 192kHz AAC over Bluetooth, which in my opinion would be more interesting. I assume not if all of the DSP stuff is done at 48kHz.
