They are indeed different.
Hold on, -- I think Deino is asking whether the PAF's J-10CP specific HMD is different to the PLAAF's J-10C specific HMD.
The pictures you posted are the HMD of J-20, and we do not have any indication that PLAAF J-10Cs use the J-20 HMD (if anything the few images that we've had of PLAAF J-10Cs with pilots wearing HMD do not correspond with some of the features on the J-20 HMD, example below (there's no separation/line between the primary helmet part and the ear part, and the positions of the IR nodes are also different):
Meanwhile the J-20's HMD is as below (interestingly, it seems PAF JF-17 Block III uses a HMD very similar to J-20's):
The other PLAAF HMD that we definitely know is in use is a monocular design used by J-16, and it's possible that the PLAAF HMD for J-10C is the same, but without more detailed pictures we can't actually tell. It is also possible that they have used or trialled different HMDs for J-10C which appear slightly similar but are still different from one another (given the two pictures of PLAAF J-10Cs Deino posted above show the HMDs as having minor differences from one another, yet still definitely not J-20's HMD)
We also cannot confidently tell if the PAF J-10C HMD is the same as that of the J-16 (some of the details look similar while some different, so at best they are cousins, but likely not the same exact model) by extension.
