Sennheiser has designed its fair share of classic headphones over the years starting with the number ‘6’. The HD 600 and HD 650 both fall into this category, but will its new HD 660S2 be one we can look back on in a few years with a similar sense of fondness?
As part of the design process for these new audiophile headphones, Sennheiser has listed to feedback from customers who own the previous HD 660S model, taken it onboard, and used it to help shape the sound quality of the HD 660S2.
And the result, according to Sennheiser, has been an upping of the ante in terms of detail, dynamics and bass. How? Sennheiser has implemented a number of design tweaks, including improving the airflow around the 38mm driver via a new vented magnet system. It has been designed this way to reduce distortion and help deliver a more dramatic and dynamic listening experience. The HD 660S2 also use a lighter aluminium voice coil than the previous generation, while impedance matches Sennheiser’s HD 600 and HD 650 models at 300 ohms.
“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,” said Jermo Koehnke, Sennheiser Audiophile Product Manager.
The design features plush ear cushions, an eye-catching jet-black finish and bronze accents. Being open-back, you’ve also got outer mesh grilles which allow you to peer into the inner sanctum of the headphones.
In the box, you get a storage pouch and two 1.8m (5.8ft) detachable cables, one with a 6.3mm single-ended stereo plug and the other with a 4.4mm balanced plug.
The Sennheiser HD 660S2 are available to pre-order now and go on sale on the 21st February for £499 (€599 / $600).
