"1. Those are all patents for DSP processes particular to identifying voice signals and separating
voices from background noise, every single one"
For example:
Patent 8,280,072
Microphone array with rear venting
Is not only about DSP but also about physical placement of the microphones:
View attachment 2110468
Patent 8,019,091
Voice activity detector (VAD) -based multiple-microphone acoustic noise suppression
Uses an accelerometer to detect vibration in human tissue:
View attachment 2110475
Patent 8,467,543
Microphone and voice activity detection (VAD) configurations for use with communication systems
Describes the physical location of the microphones used to capture sound and noise:

"2. None of them have anything to do with traditional phase
cancellation."
Correct, the Reddit poster didn't claim that Jawbone is suing Apple about ANC patents. Is about algorithms and
physical innovations that make the ANC to perform better. If Jawbone owned ANC patents, then Apple would have to REMOVE the ANC from his products, which it didn't did (maybe except in the iPhone 13 and 14). They are just performing worse.
"3. According to RPX the suits pertain to Google and Amazon voice assistant devices, not hifi devices with ANC."
I would left the case court link here and quote some relevant parts (just a very small sample of the 65 pages).

INFRINGEMENT ALLEGATIONS
22. The ’091 and ’058 Patents generally describe acoustic noise suppression with a voice activity detector that senses vibration in human tissue associated with voicing activity.
24. Apple has manufactured, used, marketed, distributed, sold, offered for sale, exported from, and imported into the United States, products that infringe the ’091 and ’058 Patents. For example, noise suppression techniques are incorporated into Apple products with voice activity detection devices including, but not limited to, Apple ear buds and smartphones. For example, this functionality is included and utilized in the Apple AirPods Pro. The AirPods Pro include “dual beamforming microphones” and a “speech-detecting accelerometer.
25. The ’072 Patent generally describes acoustic noise suppression with an array of physical microphones which forms an array of virtual microphones.
26. Apple has manufactured, used, marketed, distributed, sold, offered for sale, exported from, and imported into the United States, products that infringe the ’072 Patent. For example, this functionality is included and utilized in Apple products with omnidirectional physical MEMS microphones which form virtual beamformed microphones including, but not limited to, Apple ear buds, smart phones, tablets, wearables, and smart home devices. For example, upon information and belief, the Apple AirPods Pro earbuds comprise arrays of at least four physical microphones and two beamformed microphones, the outputs of which are combined to reduce the noise of a signal. On information and belief, the AirPods Pro earbuds combine the outputs the signals generated by the beamforming microphone array of each earbud to further reduce noise
33. The ’543 Patent generally describes communications systems comprising a voice detection subsystem and a denoising subsystem.
The ’543 Patent also describes microphone configurations wherein a first microphone is oriented toward a talker’s mouth, and a second microphone is oriented away from a talker’s mouth, such that the denoising subsystem may subtract noise associated with noise from an acoustic signal that includes speech and noise
34. Apple has manufactured, used, marketed, distributed, sold, offered for sale, exported from, and imported into the United States, products that infringe the ’543 Patent. For example, noise suppression techniques are incorporated into Apple products with voice activity detection devices including, but not limited to, Apple ear buds and smartphones. For example, this functionality is included and utilized in the Apple AirPods Pro and the iPhone 12 Pro Max. The AirPods Pro include “dual beamforming microphones” and a “speech-detecting accelerometer.” 11 At least one microphone of the AirPods Pro ( e.g. the lower microphone) is oriented towards a user’s mouth, while at least one microphone is oriented away from a user’s mouth
