That was my first thought honestly since the clamp on sennheisers is already pretty skull crushing lol.
It really just depends in my opinion when it comes to Sennheiser specifically since I can’t really recommend 650/6xx due to it’s 3 blob imaging and 600 isn’t that great about it either. From my experience the best sennheisers are the 560s, 58x, and 660s. Though I agree on the 560s in terms of competitive gaming vs the 660s with you here, I think my takeaway there though is the lack of pad swaps on it like this. To my knowledge, pads designed for the 600 series can’t be used on the 560s… now I know that modhouse makes an adapter ring of sorts, but I am not sure if this will work to allow attachment of the pads… let alone which of those adapter rings, made more so since they never seem to respond to emails. Less someone has some info on this… may try to fit them anyway. My largest complaint about 560s is that my ears rub the inside portion that sticks out from the speaker seen in the picture as example, and the pads squeeze my ears a bit so I was searching for something a bit more spacious if possible
I find this with most of the pads that the bass just feels overly bloated with them so I use them casually not for competitives
the pads are expected by Friday, so we will see how they perform for sure.
