Does the Maxwell's sound a lot better on PS5 over the official Sony Pulse headset for the console?

I'm looking to upgrade my Pulse PS5 Headset and I'm just wondering how much better this would sound in comparison? I'm only going to use it for immersive audio as I don't play multiplayer games so I'm going to take the mic off it, if I bought it. But I'm just wondering if these would sound loads better? Also how many devices can these be paired with without unpairing

Also I've had problems connecting third party headsets, earphones to ps5 via bluetooth in the past, as the console says the device isn't supported. Do these work fine and handshake perfectly each time you turn the PS5 on?
