Do you have any sources for that claim?
As far as I understand (and based on what I've seen in some Bluetooth debugging menus at least a few macOS versions back), for HFP they just use regular mSBC.
That's an optional codec for HFP (while SBC is mandated for A2DP), and a step above absolute potato quality G.711/PCM u-law, but still part of the regular Bluetooth HFP specs.

More modern Airpods use AAC-ELD, which is way way better than mSBC. Still not as good as it could be, but pretty decent and sounds far less muddy. Basically no support in Windows et al though.
