Press release Sennheiser HD 660S 2:
"Our new Sennheiser HD 660S2 offers listeners what they requested most from the headphones’ predecessor,” says Jermo Koehnke, Sennheiser Audiophile Product Manager. “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.”
Sennheiser claims that The HD 660S2 mount a new improved transducer airflow and a refined voice coil's for a warm bass characteristic that pair perfectly with its silky-smooth treble performance and allowing the timbre of any instrument part to stand out across the entire frequency spectrum.
By reducing the voice coil's weight, impulse response improves, bringing hyper realistic textures to the forefront of any performance reproduction. The overall experience is smoother and warmer than the original HD 660S, thanks to that reduces the distances between select peaks and troughs.
The overall impedance matches now the HD 600 and HD 650, moving from 150 ohms to an audiophile-friendly 300 ohms, for a better dynamics and low distortion.
Designed in Germany and manufactured at Sennheiser's Ireland production facility. The transducer surround drops the resonant frequency from 110 Hz (original HD 660S) down to 70 Hz for hefty kick drums that move with ease. Outer mesh grilles are crafted to manage airflow at the ideal impedance for exquisite open-back listening sessions.
HD 660S2 ships 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 Sennheiser HD 660S2 will be available for pre-order globally from 8th February 2023 and will go on sale 21st February 2023, with an RRP of £499 / €599.
