Is this model better or 660?

You have to understand that the Sony Z7M2 are 56 ohms so they are easy to drive. Now on the other hand the 660s are 150 ohms and need a little more power to drive them. Now the 660s2 are 300 ohms which need more power. I have the 660s and have no problems with them. I want to get the 660s2 but don't want to take a chance on buying them and I can't drive them with my setup. Hope this help you out. Have a great day.

Would these be great when used with a Steam Deck?

Thanks for your question. The HD 660S2 will go very well with Steam Deck. World Wide Stereo – since 1979 – and a proud authorized Sennheiser dealer.
