Features

 

HD 660S - The perfect blend of power and control, the HD 660S is a powerhouse open-back headphone with the versatility to connect you to the deepest corners of your music collection.

A Direct Connection To Your Music

Known for their engaging signatures and liquid-smooth response, HD 660S predecessors HD 650 and HD 600 shattered performance barriers in the audiophile headphone category. The HD 660S transcends the best of that storied DNA with supernatural speed and effortless instrument reproduction-even at the bookends of the frequency spectrum. Utilizing an all-new transducer and specially ventilated drive unit, the HD 660S delivers the revealing, tack-sharp detail audiophiles demand without sacrificing the engaging dynamics that make music so enjoyable.

 

 

From Our Ears To Yours

In just one listen you will understand why the HD 660S is so special. Thousands of listening sessions later its purpose is even clearer. What you hear each and every time is the result of an open-back earcup mated to a new transducer tuned for the modern audiophile. Its speedy response is perfectly suited for reproducing those frequency-stretching recordings with confidence. Thanks to an aluminum voice coil, the 38mm diaphragm remains nimble for ultra-quick impulse fidelity across the board. This activation and rest behaviour unlocks the capability to communicate tonal and spatial characteristics precisely.

 

Meshing Together

The steel mesh found on the HD 660S drive unit is interesting in design but most impressive when it comes to performance. It completes the ventilated driver, offering consistent control of air displacement to reduce turbulence. As a result, diaphragm travel is pure, letting the music-and only the music-shine in a perfect balance of integrity and expression. The steel composition allows for much tighter production tolerances, ultimately contributing to remarkably consistent characteristics of each HD 660S produced. When combined with the open-back earcups, the sound emanating from each transducer is completely free to expand, just as it would in nature.

Capability, Meet Versatility.

Today's audiophile has more component choices than ever. We optimized the HD 660S for efficiency on a wider range of devices to accommodate the varying levels of power present in output amplification circuitry. At 150 ohms, the HD 660S is the perfect partner for dedicated amplifiers, A/V receivers, and audio interfaces alike-the magnet is more powerful than its predecessors, and thus easier to drive regardless of how your setup changes over time.

 

Handled With Care

Every HD 660S we produce has experienced a matching regimen to mate each transducer from our Ireland manufacturing facility to its opposite-channel counterpart. These tolerances are extremely narrow and when bolstered by automated assembly processes, ensure that your HD 660S experience is consistent with those all over the globe. We designed it with thoughtful, lightweight materials invisible to the acoustical system without sacrificing the durability needed for daily, all-day use. With a never-ending supply of music to consume, we wanted every touch point to be soft, luxurious, and durable for those extended listening sessions.

 

It's All About Connection

We packed your HD 660S with a versatile set of essential cables, each one impedance-matched with ultra-low capacitance. The �-inch / 6.3mm stereo connector offers the audiophile-standard plug for connection to devices such as headphone amplifiers and A/V receivers, digital audio players, computer-based workstations, analog gear, and more. A balanced, 4.4mm connector opens a pathway to a newer generation of balanced output devices (headphone amplifiers, digital audio players, etc.) that embrace this compact plug's superior stability over time. A balanced headphone setup offers an even lower noise floor with great dynamic range when connected to balanced source/amp circuit outputs. The listener will thus experience a wider soundstage, tightly controlled transients and impossibly-clear instrument separation. Each cable is 9.8 feet / 3m long to accommodate unencumbered listening on gear deep within your shelves, studio, or desktop, and a flexible adapter is included to reduce the 6.3mm to 3.5mm. An optional balanced cable (CH 650 S) is sold separately for simplified connection to 4-pin XLR jacks.

Quality Reference Headphones

I work in audio software, with these headphones I have noticed noise and aliasing where otherwise would have been difficult, they sound so flat I often think I'm listening through monitors.

HD 660s

Fantastic headphones , but don't get these unless you have something able to drive them. Once I got the right headphone amp that was able to drive them properly they are just pure bliss.

Possibly the best I've ever tried

While I don't own the HD660 S, I own the HD 650's and have been blown away at how good they sound. Clear, amazing definition creating an atmospheric listening experience. It's like the audio is floating around your ears. My friend who is a music producer and audio engineer has a pair of the HD660's and after trying them I think they are as soon if not better than the 650's. You won't be disappointed.
