The Sennheiser HD 660S has an eye catching new matte black and anthracite design. It looks classically elegant with some hints of contemporary influence. It is truly a symbol of sophistication.
With High Quality Sound, the HD 660S also gives you High Comfort. In spite of its strong build, this pair is very lightweight. The elliptical ear cups are shaped according to the anatomy of the ear and sit perfectly over your ears giving you superior comfort. With comfortable earpads and its open construction, you can listen to music on these for hours on the trot.
The HD 660S has exceeded its predecessor HD 650 in terms of the sound output. With a crisp and defined bass, clear mids and pleasantly natural treble, it offers an exceptional soundstage response. You hear every detail and expression of the songs you play that takes you on a completely different journey full of emotions altogether.
Built with the new Transducer Design, The HD 660S offers a much better performance as compared to the HD 650. It is engineered with a specially manufactured stainless steel fabric attached to the diaphragm that facilitates better control of the diaphragm movements. Moreover, extremely light aluminum voice coils ensure the highest impulse fidelity. The transducers are carefully selected and paired by hand to ensure consistently narrow (±1 dB) tolerances.
The HD 660S is much more versatile as it can deliver reference-class sound when connected to hi-res mobile players even with its lower impedance.

"Shure has a winner on its hands; we can’t praise the 1840s enough. This is a wonderfully musical pair of headphones that comfortably justify their price." What Hi-Fi |

Read MoreOnce again thanks to Headphone Zone. Loving this very much. More clarity after 6 months. Great Head Phones SENHEISER. What a natural Sound. If you got a proper DAC & AMP it will be more fun with natural instrumental sounds and thumpy Bass (not much but enjoyable). Worth the Headphones.
I reviewing this once again after unboxing. Really a good package, for this thanks to Headphone Zone for a good package and very fast delivery. I am not a audiophile, but these headphones are rocking. Without DAC/amp its sounds good when connected to my TV & PC. With mobile it's really needs a DAC/Amp. Waiting for my XD-05, after that I will mesmerize with these headphones. Without thinking go for these. These are good Headphones. And Headphone Zone, you are awesome. Go Ahead
Hey Syed, we're so glad to know that you loved the product. Thank you so much for the detailed review this will surely be a great help for the others!
These headphones from Sennheiser are totally worth the asking price. Vocal and Imaging kings. If you are looking for a lot of bass, I think you should look at the DT 1770 PRO probably. But for vocal focused music there's nothing that comes close in this price range.
These can be run from a good laptop and even a good high end phone in my opinion. They reach a suitable volume at 80% on my Samsung S10+. But I am sure that a good DAC/AMP will increase the capability of these headphones. An amp might even increase the bass response of these headphones. I didnt take them off on the first 4 days after I got them!!!

Oh, thanks Headphone zone, just received my order within 2 days, I am in journey excited to see the product, after unboxing I update my review. Waiting for my Headphone ampp xd-05 now. Great delivery thank u so much. Giving stars without seeing the package. Call received that my package arrived at home.
Hey Syed, we hope that you will love the product even more and we know you will for sure!
Well, i have so many things to say about the HD660s. It has an immersive sound experience where it is also easy to drive. The inclusion of a 4.4mm balanced cable is a icing on the cake in the package. The sound has a deep quick bass, lush vocals with beautiful natural tonality, and brilliant staging too. Previously I had owned hd6xx and was not satisfied with its veiled dark signature. Believe me as a user of both, the HD660s is a brilliant pair and will satisfy your needs easily.
