After giving these a fair bit more time (a week or so), they have become a keeper and I won't be returning them. I've become more accustomed to the closed back nature, compared to the open backed headphones I'm used to and the convenience of a wireless set for console gaming makes such a difference compared to using a Creative G6 and draping cables across the lounge floor.
Added to that, these things just sound so good with music, compared to any other wireless gaming headset, so they become a real 'jack of all trades'.
I seem to be lucky with connection issues as I don't have any. No crackling on wireless or Bluetooth (despite my PS5/Wireless dongle only being about 2 feet from my router?).
The only issue that remains is the headband comfort - I had some Dekoni nuggets on but one got knocked off earlier so I've had to go back to the standard headband - just wish the padding was better.
