SENNHEISER HD 660 S - HiRes Audiophile Open Back Headphone

Bought these along with the Neuman NDH-30s. Liked these much better. They are a little tight on your head starting out but have become alot better with use. Sound is phenomenal. They have excellent sound and have a warmth that comes with the Senheiser 6xx line. They are much better than the NDH-30s which have been returned. I also have the Seinheiser 400 pros which are not as good as these. These are much better bang for the buck i would buy these again especially with the price they are now. Worth every dollar.

Received these as a purchase through my savings conservatorship since Im disabled. Had some extra money laying around and decided to pickup a pair of HD660S. Am probably going to sell my Ananda, Sundara and SR225x after doing comparisons this afternoon. I was using my Grado for symphonic music because it really can attain full driver excursion and give you that punch when the orchestra strikes all at the same time loudly. 660s cant do that fully the same as the Grados but get at least half the way there. Adittionally the grados had a harshness and ring in the high treble when listening to older symphonic and opera recordings because of the nature of the recording technology at the time. The 660s seem to eliminate this hiss on older symphonic recordings which is a good listening comfort plus. I was using the Anandas for mostly pop and jazz and while they have a better brilliance and resolution compared to the 660s I would say the sennheisers are about 80 percent there compared to the Ananda especially in detail and focus. And the final reason Im probably selling the others is that the 660s can do relatively good metal, rock and electric guitar music where the Anandas for this genre just sounded bad (too quick of a release of notes, harsh highs, unfavorable tonality). The 660s seem to be a jack of all trades and Im really super happy I got these. Everything Ive thrown at them is overwhelmingly positive. If you have just one headphone to own I would highly consider these.

Quick shipping and great product. Love the noise cancellation and comfort of these headphones. Sound quality is excellent. Great gift for Christmas

Very neutral and clear

Personally, the added wearing confort and less listening fatigue are well worth the upgrade. HD560s was too analytical for me and it gave me ear pain after 2 mins of listening. My setup is DragonFly Black+Apple Music.

Excellent sound overall

These headphones sound very nice, they are open back though so there is no noise cancelation at all, probably best to research what open back is as well if you don’t know (I didn’t know before buying these). Another note is for best sound quality I would reccomend an amp and maybe a DAC depending on your setup, I would reccomend research on that as well don’t just go with the same brand for the amp/DAC because it’s a bit overpriced for what you’d be getting. All of that said I’ve ordered an AMP and will see how they sound with that in mind

Sounds amazing. I’ve been in the process of re ripping my whole music collection in lossless and these headphones play everything clearly and with great detail. I don’t have any other high end headphones to compare too as this is my first foray into audiophilia but I think it was an excellent first step that will keep me satisfied for many years to come.

good sound quality

Noise cancellation- yup, he can’t hear me when I yell up the stairs. Perhaps a little too well.
