Not sure if this would be your cuppa, but the Hifiman HE-R9 is another option…
I suggest also considering the Mark Levinson 5909. Wireless, also has active noise cancelling.
Note that most Bluetooth connections actually use lossy compression (i.e. AAC) to deliver audio. See this link - What are Bluetooth Codecs?
Sony’s LDAC transmits up to 96 kHz / 24 bit PCM losslessly. The Mark Levinson headphones support this codec, as does your Pixel 6. The only question mark is the iPad Pro.
