## Questions & Answers

**Q: Is this model better or 660?**
A: 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.

**Q: Would these be great when used with a Steam Deck?**
A: Thanks for your question. The HD 660S2 will go very well with Steam Deck.
