## Overview

The Sennheiser HD 660S2 wired audiophile headphones deliver natural, relaxed high-fidelity sound with enhanced sub bass thanks to a 42mm airflow-optimized transducer and ultra-light 300-ohm aluminum voice coil. Featuring an open-back design for exceptional comfort and ventilation, these headphones cover an expansive frequency range of 8 Hz to 41.5 kHz. Crafted with German engineering and Irish manufacturing, they come with detachable cables and a vented magnet system to minimize distortion, making them ideal for professional-grade music listening and long sessions.

## 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: 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.

### ⭐⭐⭐⭐⭐ The one to rule them all
*by L***S on 13 July 2026*

EXCELENTE! Finalmente encontrei o headphone versátil definitivo! Ja tive Beyerdynamic DT 990 PRO, ja tive o DT 900 Pro X (muito inferior ao 990 PRO), ja tive monitores Extreme Ears moldados especificamente pra mim…nada foi tao versátil (musica, games, edição…) pra mim quanto o HD 660S2. A EQ dele é impecavel, boa quantidade de graves, e medios e agudos bem balanceados!
