Sennheiser Consumer Audio HD 660S2 – Wired Audiophile Stereo Headphones with Deep Sub Bass, Optimized Surround, Transducer Airflow, Vented Magnet System and Voice Coil – Black

Insane sound quality, detail, and bass output – Great for immersive video games
Quite a few people will say these headphones aren’t great for gaming. Ignore those clowns.Video Games: 10/10The issue is that 95% of headphone reviewers when asked “what makes a good pair of headphones for gaming” – almost exclusively look for the widest soundstage possible and super clear treble. Which I mean, is great for pinpointing footsteps. But there are people out there who play more than just FPS games. If you’re a solely hyper-competitive FPS gamer, maybe something from the Hifiman/Beyerdynamic lineup is better for you. But I would recommend these cans for everything else.If you play any games that are immersive in nature or are known to have good sound quality, such as Cyberpunk 2077, Elite Dangerous, or Elden Ring. You will love these headphones. But, even in games like Rainbow Six Siege, I didn’t perceive any noticeable drop in my perception of where people were compared to my old cans which were the HD598 CS. In fact, that aspect is pretty much the same, and hearing gunshots and explosions in Rainbow Six was pretty jaw dropping as well. You can hear the rumble of an impact grenade from the other side of the map sort of bellow in your ears. The low/deep growl of a deagle firing off sounded impressive as well. I did EQ mine on the low-end to output some nice rumble.Cyberpunk 2077 was easily the game that blew me away the most. It legitimately sounded like a different game to me – it’s THAT drastic of a difference. I heard things I hadn’t heard before – as if this is how the game was MEANT to sound. It literally makes me feel like I’m there when I hear cars rumble past me on the street, and I think it’s as close to life like as you can get from a pair of headphones. In another instance, there was a highway above me and surrounding me was a market full of people talking, in game music (like from radios), advertisements, etc – and I feel like I’m standing there, in the market. Imagine the cars from above encompassing your entire soundstage in the background, like further away, but the details of the market still sound closer and don’t lose their detail.Music: 9/10For music, there’s plenty of other reviews that cover that, but these don’t disappoint. I mainly listen to video game OSTs, rock bands like Cage the Elephant, or metal like Sabaton. Definitely an improvement over my old 598 CS.Movies: 8/10I haven’t tested these out with movies/TV shows too much so I can’t give a fair opinion on that, but so far they sound good, nothing yet that has super impressed me.Comfort: 9/10These feel fantastic, some people claim the clamp force is too tight, but it feels just right on my normal sized head with normal sized ears. They might feel a bit tiring to wear for prolonged periods, but supposedly this will subside with time.Overall: 9/10I am truly impressed by these headphones. The details, bass, sound quality, and imaging capabilities of these blew me away. Easily worth $400 on sale. If anything, it makes me appreciate the source of audio I am hearing more. For example, I can more easily tell if a game had a higher quality audio team working on it, or if a song was produced in a studio vs some trash recording.Sidenote:I am someone who likes emphasized bass, neutral mids, and neutral treble. I find emphasized treble to be annoying and shrill to listen to. I was also that kid in high school who would have to cover their ears completely during fire drills (and it seemed like I was the only one) – so if that sounds like you then you probably have the same tonality preferences as me. I also tested these with a Fiio K7 and Fiio E10K as my amp/dac sources.

I have 4 pairs of strictly-wired headphones. I’ll put notes on each below, with these Senns noted last.Neewer nw-3000: These are cheap but actually worthy of mention. They sound sort of muffling. However, I went through a process of making careful equalizer adjustments while switching between these and quality headphones, and I found that I could make them sound like something approaching quality. They actually win over all these others with respect to looks. They are a knock off of the classic Sony MDR line of headphones, but actually look better. The stitching is tight and impeccable. I twist them all around and drop them, and there is not a tear. The headband adjuster is metal, and it has numbers and lines. There is a nice silver trim. The headband is wide and thick, and it doesn’t bother my bald head. They fit perfectly snug. I use them for video conferencing because they can twist and be worn on one ear only. They are good for watching educational videos and presentations.AudioTechnica M50x: These are good-ol’ classics. They are portable and can be plugged into anything. It’s a pleasant sound profile, and I love the way they twist and bend for the perfect snug fit.Beyerdynamic DT770-80ohm: For me, these are still my best-sounding headphones. I listen to a lot of symphonic music, and these are nicely analytical. I can have an ideal sonic look-around at details coming from the lowest double bass to the highest flute. However, they’re not as comfortable for me as they are for others. I find that there’s not enough clamping pressure. They’re bulky and put too much pressure on the top of my head. Others with glasses and a lot of hair, I think, like the comfort of these a lot.Sennheiser HD 660S2: These are light and snug. They break in perfectly. I teach online with them on, and I can wear them all day without my ears getting hot. I hear myself talking like I’m not even wearing headphones. They are perfectly open-backed. Sennheiser, with these, abandoned the strictly neutral sound profile. They extend far down into the low end without messing up the sound of everything else. If Beyerdynamic ones offer a perfect middle-row position, these Sennheiser ones put you right up front. This can be good and bad. Anyway, if I had to keep one pair, it would have to be these.

Son unos audífonos excelentes (a mi parecer).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 🙂
