## Description

From thundering timpani, to the melodic sound of a guitar, the impressive singing voice of your favorite artist, or the beat of electronic dance music, nothing creates drama like powerful bass. Ideal for music lovers, the non-fatiguing, high-end HD 660S2 now delivers even more impact and emotion. Our engineers optimized the HD 660S's surround, transducer airflow, and coil to double the sound pressure at the lowest octaves. You can feel the lowest note on the piano (27.5 Hz) or the kick of the bass drum (45-60 Hz) as if you were there at the recording studio, allowing you to pick out individual instruments and discover new sonic details. The relaxed sound and open-black design make it an extremely comfortable headphone that is also suitable for long listening sessions. The headphone's warm, relaxed sound is reflected in its timeless design and elegant bronze accents. With warm tuning, smooth treble and strong bass, the standard-setter for extended listening is now also the standard for extended bass.

Review: truely cheap truly crap - the original hd650 is 10 times better , bass cannot hold , was in a cheap box dont buy them
Review: Not worth the hype - Well…a few hours in and let’s say I am not overwhelmed. Very little difference between these and XM5s and maybe not so good. Returning.

## 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.
