Introducing the Next Generation of Audiophile Sound from Sennheiser: HD 660S2

The Audio Store is thrilled to announce the launch of the HD 660S2 headphones from Sennheiser in India. These headphones set a new standard for audiophile sound and expand the capabilities of the 600-series family. Sennheiser has crafted these headphones based on feedback from the hi-fi community, ensuring that they balance reference-level detail with an engaging frequency response.

The HD 660S2 headphones are designed to deliver a more dramatic listening experience with greater intensity from enhanced sub-bass tuning. They extract dynamic impact and emotion from your favorite recordings and offer a delightful new way to experience music.

"Our new Sennheiser HD 660S2 offers listeners what they requested most from the headphones’ predecessor,” says Mr. Kapil Gulati, Sales Director – Consumer Hearing Business, Sonova. “With precision and power like no other and new sensitivity across all frequencies, listeners will hear details they’ve never heard before, especially at the lower end of the spectrum.”

Improving on a beloved classic while retaining its best traits was a challenging task, starting with the lowest end of the frequency plot. The HD 660S2's warm bass characteristics pair perfectly with its silky-smooth treble performance and trademark vocal presence, allowing the timbre and uniqueness of any instrument part to stand out.

These headphones deliver a refined listening experience thanks to improved transducer airflow and a refined voice coil. The overall experience is smoother and warmer than the original HD 660S, thanks to a tuning that reduces the distances between select peaks and troughs. The overall impedance matches that of the HD 600 and HD 650, at an audiophile-friendly 300 ohms, for punchy dynamics and impressively low distortion.

Designed in Germany and manufactured at Sennheiser's state-of-the-art Ireland production facility, the HD 660S2 headphones are built to last. They feature plush earpads and cushy headband padding, placing the revised 300-ohm transducers at the optimal distance from the ear for a spacious soundstage with an abundance of detail, even for extended musical exploration.

The HD 660S2 headphones are versatile enough to connect to vintage classics and modern solutions alike. They ship with two 1.8 meter (5.8 ft) user-detachable cables that terminate to 6.3 mm (1/4-inch) single-ended stereo and 4.4 mm balanced stereo jack plugs, respectively. A 6.3 mm to 3.5 mm (1/8-inch) adapter is also included, for use with popular hi-fi gear from DAC-amps, DAPs, and dedicated amplifiers such as the Sennheiser HDV 820.

The HD 660S2 headphones come with distinguishing bronze accents complementing the elegant jet-black finish, all of which is protected by a storage pouch.
