I’ve not tried these particular ones, but gel ear pads with noise cancelling headphones is pointless in my experience

The gel vibrates with exterior sounds and passes through to your skull, cancelling out the cancellation!

For what it’s worth, these wotsit cushions really bumped up the comfort on my Steelseries Nova 7s to the point where I find myself considerably less likely to need a break after an hour. Out of the box, they were cooking my head.

One thing to note with big puffy replacement ear bands is they do affect the frequency response of your headphones.

I have a pair where the aftermarket pads are maybe 5mm thicker than the factory ones and they DESTROY the already bad bass response of my headphones. The different material also absorbs sound different so it changes how all frequencies sound a bit.

So if you’re already lacking in bass just know they will make it worse.
