Got these cans for 400 dollars for black Friday.
SOUND:
These headphones sound better to me than the rest of the 600 series simply due to their better sub-bass performance. They have a pretty wide soundstage, have excellent instrument separation and sound good with all music I have thrown at them. The mids perform excellently, just as the rest of the HD600 series, and the treble is sparkly and nimble but not fatiguing. These are a good, balanced, warm sounding pair of headphones that are well worth the price that I bought them for, however I could not recommend these for $600 as this price forces competition with a higher class of headphones.
COMFORT:
These headphones are the most comfortable pair I own, with nice soft earpads and a perfect amount of pressure that gets a good acoustic seal over my ears. My head is on the larger side, so as to the issue of clamping force, I really did not feel that they clamped too tightly. These are the kind of headphones that I could wear comfortably all day and forget I even have them on.
DRIVING EQUIPMENT:
To those that have mentioned an unimpressive performance from these headphones, when used without a headphone amplifier or properly specified piece of equipment, these headphones tend to sound a bit soulless, empty, or a bit muddy. However, the great thing about the HD600 series is that they tend to scale very well with good sound equipment. The difference in sound that an entry level Schiit DAC+Amp stack made was well worth it and really made these phones come to life. This does mean, however, that you should also consider the cost of an amplifier and DAC unit as a cost included with these headphones, so at minimum another $200 added onto the already expensive price. There are many other good options for headphones that are easier to drive and do not require a dedicated amp for this price range, so if this isn't for you, I would look elsewhere.
Overall a great sound albeit a bit overpriced at MSRP.

Sennheiser HD 660S2
Dive deeper into legendary sound.
Enjoy your music on a completely new level. An intimate, relaxed sound signature combines with outstanding precision and exceptional comfort — and now, extended sub bass — for a deeply moving experience.
Your new desert island headphone.
Every high-end headphone has its own unique personality. What if you could only own one?
Ever felt goosebumps from sound so real, it was as if the source was in the room with you? The non-fatiguing HD 660S2 gives people who love music an intimate way to connect more deeply with their favorite songs and artists. Breathtaking resolution and precision take you closer than ever to instruments and vocalists. Yet the sound is natural and balanced, never harsh or brash.
This warm, inviting signature combined with extended sub bass makes listening uniquely pleasant and rewarding. And with comfort this good, it practically begs you to keep going for endless sessions. That’s how HD 660S2 combines the best of many worlds to give you an intimate experience you won’t want to live without.
Sub bass expands the entire sound.
Double the sub bass heightens your listening experience.
Traditionally, audiophiles don’t get too excited about sub bass. It can easily get sloppy or boomy and become a distraction. And that’s a shame — because there’s so much more to experience here than just the gut punch of a kick drum. Did you know the low B of a 5-string bass vibrates at 30.9 Hz? Or that the lowest note on a concert piano comes in at 27.5 Hz? And of course, extended sub bass makes bass-heavy genres sound fantastic, too.
And that’s the magic trick here. In doubling the sound pressure at the very lowest frequencies, we’ve nevertheless retained extraordinary precision and balance throughout the sub bass, mid-bass, and beyond. Most impressive is how this affects the listening experience. Extension on the low end changes everything — by creating more space for the sound. Against a deeper backdrop, highs feel more brilliant, the soundstage deeper, emotions stronger.
They feel as great as they sound.
Comfy slippers, your favorite jeans, the HD 660S2. Some things just feel awesome to wear.
The velour earpads of the HD 660S2 can only be described as a tactile pleasure. With just the right amount of tension for proper acoustic positioning and supple padding, the headband won’t draw attention away from your music, either. As an open-back design, the HD 660S2 gives your ears an extremely comfortable climate, even for super-long sessions.
The low total weight and ergonomic headband rule out any potential discomfort on top of your head as well. Combined with excellent build quality made in Ireland, you’ll quickly grow attached to a listening experience that’s as physically pleasing as the warm, non-fatiguing sound at its heart.
How do you one-up a line of legends?
Some of the most neutral headphones in the world are a tough act to follow.
As far back as the HD 580, high-end Sennheiser headphones have inspired generations with their balanced, natural reproduction. Recognized as benchmarks for neutral audiophile sound, the HD 600, HD 650, and HD 660S all share visible and audible DNA with the HD 660S2. The revised coil of the S2, for instance, now matches the 300-ohm impedance of the legendary HD 600 & HD 650. This new coil also provides higher magnetic force and electrical dampening for cleaner impulse response.
The surround is now more compliant, too, dropping the resonant frequency to 70 Hz. Considerable effort also went into optimizing the airflow around the transducer. There’s more sensitivity over the entire frequency spectrum because the magnet´s air gap works more efficiently now. Taken together, these measures result in even greater precision, speed, and resolution — with double the sound pressure at the lowest frequencies.

Absolutely Great Headphone. Please read.
There are plenty of opinions on this headphone all over the internet. None are bad, but some are pretty negative. Mainly because from what I am seeing, the reviewers are reviewing the price, not the product. They are saying, you get almost as good performance from model/Brand A or B for less money, focus on the ALMOST. While yes it is true, at $600 is expensive, but make no mistake about it is does out perform other headsets in many areas. This headphone is on sale for $100 more than the HD650, which is $100 more than the HD600, so this falls right in line with Sennheiser pricing structure now, and rightfully so. I don't think it is double or triple the other two 600 series headphones, but it is IMHO is a much better headphone, and worth $100 more. Literally, if you are looking at the 600 or 650's and aren't sure which sound signature is for you, get this one if you have the budget, or wait a little while and save for it... It is worth it. It has the best characteristics of both, which you can see some reviewers stating this. I believe it was Josh Valour who said it, but I do disagree with something he said, it was something along the lines that is in between both models, and a jack of all traits, but master of none. Well, it is a more well rounded performing headphone than both of those and I believe it Masters an overall warm, smooth, well defined, spacious sound with impeccable imaging. For me and my taste it is the PERFECTING SOUNDING HEADPHONE, and exactly what I was looking for. No headphone is the everything to everyone. So be honest with yourself on what you like, based on your ears, and not popular opinions, even if it is from experts, which they are, I am not disputing that at all. I am pretty new to the whole audiophile thing. One thing. But, I have learned that you really need to spend some time with the equipment to let it sink in and let your hearing mature to the product at hand. I realized this, when I purchased the Harmnicdyne athena, reviewers raved about them. It sounded like the overall characteristic I like so I decided to give it a try. I received them, put them on and listened, I was horrified. What I hadn't realized was that my hearing was skewed by listening to the hd560s so much (I really enjoy that headphone). Doing A/b comparisons only made it worse for me. So, I decided to force myself to listen to them. So, I did, I listened exclusively for 2 days, and when I would take breaks and come back and listen to the Athena I was truly amazed at how much I LOVED THEM!!!It is really hard to compare headphones; they all have their own characteristics, just as we all have our own opinions and tastes. So, I believe headphone reviewers have a very difficult job. As some of us expect them to tell us what is "BETTER" headphone A or Headphone B, it just isn't that simple. Headphone A might be better for you, but headphone B is better for me. That is the beauty of this hobby. There is no right, or wrong, better or worse. Just learn to appreciate what your ears tell you and take all other opinions with a huge "GRAIN" of salt. Josh Valour, DMS, The Headphone Show, The Source Audio Video Group, and some others, does a great job of describing the products and giving a sense of how the product is. I watch way too many reviews. LOL. I Hope this helps someone else on the audiophile journey.Here is my current stuff incase anyone care to see. I literally started with headphones and amps a little less than a month ago. The gaming headsets, I have had for about 6months to a year, that is what started it all. I have the HD560s, HD 660s2, Hifiman he400se, Harmonicdyne athena, I am using the IFI Zen air line of products, the Air dac and Air can, both awesome to start with, and you probably won't need to upgrade for some time, key word is need, want is different. lol. For gaming I use the PC38x Sennheiser/epos, the epos H6Pro, Steel series Nova Pro wired with DAC. Sennheiser Game zero, and Audeze PenroseX, Gaming Dacs are the sound Blaster GC7, and G6 love them both but prefer the GC7 in case anyone is looking at the two.Good luck, and good listening!

Tienen unos excelentes materiales de construcción (la misma de toda la serie 600 de Sennheiser) con un tono cobre que le da otro aspecto más moderno. Los emparejo con el iFi Zen DAC y Zen CAN y hacen un match increíble.
En cuanto auriculares de diadema yo vengo de unos Sennheiser HD 599 y el salto es bastante notorio. Se escucha todo más limpio, bastante más definido y el bajo con buena pegada, los medios bastante buenos y los agudos presentes sin perforarte los oídos. Me gusta su sonido, es tranquilo, no tiene bajos súper potentes, pero son bajos que a mi gusto personal me agradan (no es como tener un subwoofer en la cabeza, que quede claro, así que si buscas un audífono para basshead, aquí no es). La escena sonora es íntima, pero sí identificas muy bien todos los instrumentos musicales. He tenido la oportunidad de probar los HD600 y los HD660S, y la verdad es que esos dos me aburrieron (evidentemente porque son para mezclar), así que decidí irme por estos. En cuanto a in ears, cuento con los IE 300 e IE 600, y estos me gustan poquito más que los IE600 y me costaron menos, eso sí, los IE600 son más versátiles por ser in ear.
Vi varias reseñas donde mencionaban que sí valían la pena pero le ponían el gran pero de su precio; afortunadamente los llegué a encontrar a un precio menor (menos de 10 mil), así que decidí arriesgarme y estoy bastante contento con mi compra.
Otra de mis preocupaciones era la comodidad. Toda mi vida he sido bastante quisquilloso con la comodidad de audífonos de diadema (he tenido AirPods Max, Bose QC35 II, Sony WH1000XM4), y siempre he tenido problemas con que me toquen las orejas o que me aprieten demasiado. Así que estos me preocupaban mucho porque leí que apretaban bastante. Los únicos audífonos cómodos que he tenido son los Bose (y son los que peor se escuchan; sin embargo, estos audífonos tienen una peculiaridad bastante graciosa (a mi parecer) y es que al inicio aprietan, pero conforme los vas usando vas olvidando que los traes puestos (supongo que es por sus almohadillas que son sumamente cómodas y la banda de la cabeza que es extremadamente cómoda, a eso agrégale que son poco pesados. Por lo que a la hora, hora y media, olvidé que los traía puestos, tanto que hasta me levanté y casi tiro mi amplificador por accidente, jaja.
En general, creo que son unos buenos audífonos, sobre todo si vienes de gamas más bajas de audífonos y buscas algo seguro. Sennheiser es calidad asegurada y se nota, se siente que te durará mucho tiempo.
Claro, nunca está demás probar otro tipo y valorar por ti mismo el sonido :)
