Description
The Sennheiser HD 660S 2 headphones take the performance of its predecessors, the HD 650 and HD 600, to the next level with its supernatural speed and effortless instrument reproduction, even to the ends of the frequency range. The natural, warm sound and extended sub-bass make it an ideal choice for audiophiles.
Enjoy the Sennheiser Sound
By using a brand-new transducer and a specially ventilated driver unit, the Sennheiser HD 660S 2 headphones are able to provide audiophiles with a sound that’s perfectly suited for reproducing complex and intricate recordings with confidence. It’s sharp, and detailed and maintains the engaging and dynamic qualities that make music enjoyable. The 38mm diaphragm is agile thanks to the aluminium voice coil, allowing for precise tonal and spatial characteristics to be communicated through ultra-quick fidelity.Meshes with Your Music
The HD 660S 2 has a steel mesh that’s impressive in design and performance. It completes the ventilated driver, which controls the air displacement consistently to minimise turbulence. Consequently, the diaphragm moves freely, allowing the music to be heard in its purest form, with a perfect balance of authenticity and expression. The steel composition enables much tighter production tolerances, resulting in consistent characteristics of every headphone produced. When combined with the open-back earcups, the sound produced by each transducer is unrestricted, mimicking the natural soundstage.Matched for Perfection
Each unit of the Sennheiser HD 660S 2 has undergone a matching process to pair the transducer with its counterpart on the opposite channel. These processes have very precise tolerances, and when combined with automated assembly, they ensure top-notch quality throughout.
Designed For Durability & Acoustics
The materials used to design the HD 660S 2 are lightweight and carefully chosen to not affect the acoustics of the system, while still maintaining the durability needed for daily, extended use.Connect to Any Source
The HD 660S 2 comes with multiple 9.8 feet /3m-long cables in the box. The ¼-inch / 6.3mm stereo connector is the standard plug for audiophiles and can be used with various devices such as headphone amplifiers, A/V receivers, digital audio players, and more. The 4.4mm balanced connector is designed for newer balanced output devices such as headphone amplifiers and digital audio players and provides a more stable connection over time.Transducer principle: dynamic, open

Sennheiser is a well-known brand in the audio industry. They offer a wide range of products catering to both audiophiles and casual listeners. Their products include open back and closed back audiophile headphones, in-ear monitors, ANC headphones, and true wireless earbuds. They are known for their exceptional sound quality and durability. Whether you're a professional musician or just a music enthusiast, Sennheiser has something for everyone.
H660S2 is very well built transducer, it's quite clampy out of the box. The clamps can be eased but stretch softly over the metal band on both side.
Sound: music is warm with mids forward. Spiciness in the treble is not noticed. Bass is also subdued.
Note: My previous headphone are 560s, Sundara, Eligia and Clears.
Comparison:
With 560s: the 560s is v shaped compared to 660s2. Mids/vocals sound so good on 660s2. But the sub bass, mid bass, highs sound bit better on 560s. 660s2 suits clasical music while 560s suits rock, electronic and pop music. 560s also tend to distort with volume and eq, 660s2 doesn't sweat with volume and eq.
With focal clear: the focal clear is best in all genre no competition but vocals are slightly prefered on 660s2
With Sundara: Sundara sound very thin when compared but excels in details and soundstage.
Overall 660S2 or any of the 6X0 series headset are must for audiophiles. This headset sings with right vocal based tracks.
Sounds very enjoyable and open and also has good imaging and instrument separation and definition to the various components of music is great. More clarity than HD 650 and also warmer but crispy sounding. I have the ifi zen stack but I like it more with just the zen dac v2 balanced output. Great headphone under 30k if you like warm sound with vocal intimacy and details of instruments.
You will enjoy the music as these sound good but little tight fit heavy when compared to competition like Sony MDR MV1 (which I owned already) . It's good looking when we compare it to Sony ones but only problem for me is it's tight fitting and I found little heavy for long listening, I can't bear these or even sony more then 40 mintues max in one go. Price could also be little better. But it's worthy one if you want to enjoy music at its best at stage live performance rather then in your head like closed back. One of the best ones in open back but again little tight fit and heavy for me.

OUR HONEST REVIEWS FROM THE CO-FOUNDERS & AUDIOPHILES

Let customers speak for us
from 4624 reviewsD32 is way better than expected. Sound imaging & separation is very good. Nice thumpy bass, crystal clear mids. Overall very value for money stuff. All bluetooth codec available. Supports aux in from DAP for hires audio. Fantastic overall.
For quite a long duration, I was looking for an budget IEM with a size that would perfectly sink within ear lobe and will not exert any pressure while being a couch potato , on one side. Atlast this is where the search ended.
Aurora is even a bit smaller in size than Sennheiser IE100 Pros, which were my only go to solution at late nights. I already referred to various other reviews about the sound signature of this tiny one, and was quite confident about the other end of the bargain any way. I will not be hence touch the audio signature stuff , since there are plenty detailed reviews on the youtube and many other forums already. It is the ergonomics which is mostly untouched area of any in ear type monitors, that was more profound for me in this case, for long duration of usage. Also liked the quality of the case supplied with , the whole package is absolutely incredible !
This iem fits like a glove, it is so well tuned. The sound profile changes based on what you plug it into.
I was searching for an IEM that fits comfortably for soo long and then I came acrosss this review by Acros. I immediately jumped on it as soon as he said it was light, because so many reviewers talk about how an IEM looks and sound signature and more but never about its weight and fit. He did a comparison with few similarly priced IEMS. This one when compared to Moondrop Aria which I have sounds awesome but it is a pain when wearing it for more that 30 mins. This one I have worn for 3 hours straight and nothing. Perfect for my needs.
I drive it with Fiio BTR3K specifically for the sound profile it offers, on the other ones it sounds too neutral. Thank you Audio Store for stocking this IEM.
Excellent delivery experience, it was a gift wrap.
My first time ordering from the audio store, really impressed.
And the device is marvelous.
Comfortable & Excellent quality. As per heard, i was looking adaptor for my Tangzu Warner sg wired IEM. This KZ AE01 fulfilled my needs for bluetooth adaptor. Music sound quality is good. Fitting is also fine. Call quality is little bit low.
Otherwise ok for bluetooth conversion of IEM.
It surely enhances all parameters of sound quality like stereo effects, vocals, all frequencies, soundstage and imaging.
I am saying it based on a week experience with multiple basic IEM like EPZ Q1 pro, Simgot EW 300 DSP, Moondrop chu 2 with hiby R4 DAP.
Highly recommended to upgrade existing budget IEM.
Although Cable is thick, its very much flexible and handy. No issues while handling and carrying it because of its thickness.
It's thickness enhances overall look of IEM.
Super Bass and ultra clear vocals in
affordable price..
REVIEW AFTER ONE MONTH DAILY USE
Initially, my set up was 'Samsung S 23 ultra + Simgot ew 300 DSP' for daily music listening hobby.
While upgrading from this set up, 1st I bought HIBy R4 DAP, used it for 10 days with same IEM and then decided to go for another big upgrade for iem. After trying existing iem on multiple phones, surprisingly I observed that 'Hiby R4 DAP' is superior even on high-end phones in terms of sound quality.
While upgrading IEM, I kept below criteria and told Mr. Pritam the same.
1. IEM with crystal clear sound with all details & balanced sound.
2. Ultra wide Soundstage & clear imaging
3. Clear stereo effect
4. It should separate Instruments sounds when there are multiple instruments in song/music.
5. It should handle bass heavy songs without compromising vocals & trebles.
6. Comfortable for long hours.
Now after using it more for one month, I can say that -THIS IEM HAS FULLFIELD EACH REQUIREMENT & ASPECT OF SOUND QUALITY.
Only downside I felt that Packaging and Case should be premium in this price tag.
EXPERIENCE WITH AUDIO STORE -
I had some options for IEM in my mind based on previous listening sessions at audio store office as well as youtube & web reviews.
I recently visited audio store office two times for some other product requirement, All those previous options, I tested all of them again. I found that Mr. Pritam's suggestion to buy MK3 over other IEMs is worthy.
Thanks a million Mr. Pritam for always helping & guiding before taking any major purchase.
Superb Cable!
Works well with Zero 2
Value for money product
I am very thank full
I really like the quality of the product not only that I really like your store Too
I want to work with your company as a employee please let me know if there is any openings
I'm an IEM guy and after a long time I've been really impressed with a speaker. And at such a fantastic price point. The sound is so smooth, you can listen to it for hours without feeling fatigued, and most important thing for me was, it sounds just as good on low volume when you want to listen to something in the background, but have guests and are going to talk over it.
Incredible separation. Very good stage, fills a 10x10 area nicely (with windows closed). Bigger area and you might feel the need for two of them (heh). Excellent details on both the bass and treble. This is very much a fun sounding speaker. Female vocals are slightly more recessed than the male ones, but the separation will ensure that they come through nicely nonetheless. Drums on this thing are just a blast (literally!). Strings are so melodious.
Last but not the least, looks are killer. Everyone notices it instantly (although it blends very well with the home decor) and asks what it is. Pick it up. You cannot go wrong.
This headphone needs some time to be given. I have sold these 2 times and bought again and now they are permanent in my collection. I now understand them and you need a seriously good amplification system and then they are much more of a lushfull/true/audiophile sound that surpasses almost all headphones under Rs. 50000 easily (including Hifimans).
It has a satisfying amount of bass
Crispy treble region and clean sound signature
Comfortable fit
Pair it with a good DAC and see the magic happen!!
Must have IEM!!
