SENNHEISER PRESENTS THE ALL-NEW HD 660S AS AN UPGRADE TO THE LEGENDARY HD 650 AND HD 600

Sennheiser has a 75-year history, past achievements, and inventions in the audio industry as a third-generation family-run company, as well as their desire to influence its future. Sennheiser's engineers work diligently to provide some of the most audiophile-focused headphones available. The manufacturing process for headphones like the HD 600, HD 650, HD 800 S, and HD 820, to mention a few, involved extensive research and development. With the same approach, the HD 660S was born. The new, high-end Sennheiser HD 660S headset outperforms the iconic HD 650's excellent performance. Sennheiser is attempting to expand its product line with the HD 660S designed specifically for the most demanding listeners. An eye-catching new matte black and anthracite design is featured on the Sennheiser HD 660S. It has a classically exquisite appearance with some modern influences. It truly represents sophistication. The HD 660S headphones provide an audiophile-grade experience that will take your breath away.

42MM DYNAMIC TRANSDUCERS AND OPEN-BACK DESIGN DELIVER LIQUID-SMOOTH RESPONSE WITH EXCEPTIONAL SOUND STAGE AND IMAGING

The Sennheiser HD 660 S is designed with 42mm transducers that deliver a liquid-smooth response. Even at the extremities of the frequency range, the HD 660S surpasses the best of that illustrious DNA with supernatural speed and seamless instrument reproduction and separation. The HD 660S delivers the revealing details that audiophiles seek without losing the engaging dynamics that make music so delightful, thanks to an entirely redesigned transducer and specially vented drive unit. The Sennheiser HD 660S is here to immerse you in rich, towering waves of sonic impact, thanks to its 42mm transducer arrangement. Its outstanding presentation and elegance deliver incredible tonality, scale, and dynamics. Without the use of boosted bass frequencies designed to colour the timbre, it offers a wider vertical soundstage and real-time timbre performance. The HD 660S has good soundstage and imaging capabilities due to its open-back design. You will be able to imagine and place each instrument considering the stage of your recording. The soundstage and imaging will give you the impression that you are watching a live performance while seated in a concert hall. This single-driver structure encourages accurate sound positioning with transparency, wide soundstage and dynamics.

EXPERIENCE HI-FIDELITY AUDIO WITH AN ALUMINUM VOICE COIL AND THE 38MM DIAPHRAGM COUPLED WITH STEEL MESH

An open-back earcup coupled with a new transducer calibrated for the contemporary audiophile produces quick responsiveness. The 38mm diaphragm maintains its flexibility for ultra-quick impulse Hi-Fidelity across the board thanks to an aluminium voice coil. The power to precisely transmit tone and spatial features is unlocked by the voice coil and 38mm diaphragm. Though fascinating in terms of aesthetics, the HD 660S drive unit's steel mesh excels in terms of performance. It completes the ventilated driver and provides reliable air displacement control to lessen turbulence. Diaphragm travel is therefore unadulterated, allowing the music—and only the music—to shine in the ideal harmony of purity and expression. Since the steel composition permits significantly tighter production tolerances, each HD 660S produced has amazingly consistent properties. The sound coming from each transducer is free to expand when coupled with the open-back ear cups, precisely delivering a holographic and airy reproduction of audio.

HD 660S PACK A PUNCH WITH THEIR CAPABILITY, COMPATIBILITY, DURABILITY, VERSATILITY, AND LUXURIOUS COMFORT

The HD 660S is much more versatile as it can deliver reference-class sound when paired with any device. With its sound pressure level (SPL) at 104 dB, it is easy to drive these headphones. The HD 660S's magnet is more powerful than its predecessors, making it easier to drive. To handle the power levels inherent in output amplification circuits, the engineers at Sennheiser developed the HD 660S for efficiency. At 150 ohms, it is the ideal partner for dedicated amplifiers, A/V receivers, and digital audio players (DAPs). These exceptionally tight tolerances, combined with automated assembly procedures, guarantee that your HD 660S experience will be exceptional. The engineers painstakingly built HD 660 S using lightweight materials invisible to the acoustical engineering without sacrificing the toughness necessary for daily, all-day use. With High-Quality Sound, the HD 660S also gives you High Comfort. Despite its sturdy build, this pair is very lightweight. The elliptical circumaural ear cups fit over your ears which provides superior comfort. You can listen to music on these for hours on end because of the soft earpads and open design.

EASE OF CONNECTIVITY WITH A VERSATILE SET OF ESSENTIAL CABLES

Sennheiser is known for designing some of the most versatile cables that are robust and provide exceptional audio transmission. A beautiful cable with numerous terminations is included with the HD 660 S to accommodate your audio configuration. It has no microphonics and achieves a stable connection. The ¼-inch / 6.3mm stereo connector offers the audiophile-standard plug for connecting to devices such as headphone amplifiers and A/V receivers, digital audio players, analogue gear, and more. A balanced 4.4mm connector provides access to a newer generation of balanced output equipment (headphone amplifiers, digital audio players, etc.) that value the improved stability of this small plug over time. When linked to balanced source/amp circuit outputs, a balanced headphone arrangement gives an even lower noise floor and excellent dynamic range. The result is a broader soundstage, precisely controlled transients, and impossibly distinct instrument separation. Each cable is 9.8 feet / 3m long to accommodate unencumbered listening on gear deep within your shelves or favourite listening chair, and a flexible adapter is included to reduce the 6.3mm to 3.5mm.
