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.

Allrounder headphones

This is an all rounder headphones. Sub bass is extended which can be easily EQ d. Treble is decent.The mids are a bliss. A note for AUDIO STORE: PLEASE DON'T CHEAP OUT ON THE DELIVERY. The headphones were sent by road claiming to be more than 2 kg. It was just 845 gm. Also if bluedart is not working out please get another delivery partner. Imagine a 30k headphones bumping around for a 1000km. The headphones wires came attached which is not correct. Despite all this thank God there was no damage to the headphones.

Excellent sound quality and comfort

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.

Mix of Enjoyment and Technical capability!

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.

emon these as these sound good but little tight fit heavy when compared to competition

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.

Thank you for your review of the Sennheiser HD 660S2 Open Back Headphones. We appreciate your feedback and are glad to hear that you are enjoying the sound quality. We apologize for any discomfort caused by the tight fit and weight of the headphones. Thank you for choosing Sennheiser, The Audio Store and happy listening!
