The new HD 660 S lets you enjoy sophisticated audiophile sound in even more listening situations. The successor of the legendary HD 650 excels with the improved performance of its new transducer design. Thanks to its lower impedance, it delivers reference-class sound also when connected to hi-res mobile players, thus offering much greater versatility. The HD 660 S is an elegantly designed piece of high-quality engineering that indulges the demanding listener with aural precision and great wearing comfort.
HD 660 S
These days I stream much more music than I play from traditional media, so I thought it was time I got headphones as good as my main speakers.
The 660S has at least as much range and presence as my big Tannoys (and the image is better, as you'd expect). They need a headphone amp most of the time, but I already had a small Arcam, which is easily good enough.
I find them very comfortable and given the quality they were a very fair price. Considering the extra convenience of being able to carry them from room to room, the considerably wider range of music now that I can search online, and my partner's delight that she no longer has to share my listening preferences ... I might even be retiring those big Tannoys someday soon.
I purchased the HD 660 S headphones directly from Sennheiser for NOK 3500. This is amazing value and a great upgrade from my previous HD 595 headphones. Time from order until I had them in my hands was less than 2 business days, and the shipping was free! Compared to my HD 595 these have more pronounced bass and great comfort with more even clamping force on the head. I have paired them with a Benchmark DAC1 which works great.
I have used headphones to produce and listen to music and also in video production. These HD660s headphones are the best I’ve used in 30 years.
The headphones give clear and detailed sound and delivery was very prompt.
