Problem with the Pulse is the build quality. Mine is having serious issues after 2 years: the protection of the foam is badly deteriorating, the button to mute/unmute is working 30% of the time and I have several other complaints. Like every PlayStation product, its not robust at all and gives the bitter impression to have been designed for you to buy a new one after 3 years.
It is still a good headset, tho, and one built with PS5 in mind, so that makes it very nice to use and it has a very good sound for the price.
(I dont want to ruin your purchase, Pulse is still a solid choice. But be maybe more careful than me if you want to avoid the problems I mentioned
I have almost finished the game and I agree with you its really good, albeit not excellent.
I read from the devs that they were working on a "cool dlc". I expect some infinite rogue lite mode, that would be really nice.
