SENNHEISER HD 660 S - HiRes Audiophile Open Back Headphone

Incredibly high quality in every way. Comfortable with a clean, abundant sound that allows you to hear every nuance.

Probably some of the best headphones Ive ever used. Balanced, clean and accurate.

A lot of people tend to criticize these headphones or even compare them to the 650 but IMO there is no comparison. I was actually pleasantly surprised. I love Sennheisers studio headphones but all the negativity behind these made me reluctant. Well dont be, these cans are absolute awesome and so easy to EQ as per your tastes.

I personally use these for gaming, mixing, and just plain listening to music. I personally can’t stand hearing my voice with closed back headphones, so these make gaming much less distracting for me. Obviously these are expensive if you’re just gaming, but if you also care about audio quality then these are the ones for you.

Excellent sound overall

Nice brand of headphones! Few thinks im disagree with- first the package cardboard come damaged, inside box the foam protecting the item looks an feeling chip and human hair on drivers pads and the protecting foam around!

These are so good. Im not an audiophile. Coming from a pair Audio Technica m50xs Ive been using for 6+ years, those are great headphones but these are on a whole different level. Really great headphones and super comfortable.

This headphone is good, but not a great buy compared to Sennheisers own HD 600/650/6xx series.

I have tried/owned the following: PC37X, HD598, HD599, HD600, HD650, HD700, HD800, HD 6XX, HD 58x and MANY others from other brands. The 660S is overall, the best headphone Ive heard. It has no flaws. The tuning is what I would consider as perfect as you can get for a dynamic driver. No harsh highs, no recessed mids, no overpowering bass. Amazing imaging. Comfortable as any other HD variant. Better looking than any other HD variant.

I love these, the earphone itself feels a bit stiff. The sound is great, and got them on sale so awesome value there.
