When it comes to high-end headphones Sennheiser knows more than a thing or two. Its original HD 660S open-back cans were an audiophile sensation for many listeners, acting as an ideal at-home listening experience.
Now these open-back audiophile headphones have the ultimate upgrade: a second-generation model! Named the Sennheiser HD 660S2, these updated cans promise to deliver even more for audio fans. An early 2023 contender forthe best wired headphonesalready, perhaps?
So what exactly is new in the HD 660S Mk2? A quick glance at the specification reveals a small but critical detail: the frequency response is wider than before, covering 8Hz through to 41,500Hz. That’s an even lower-end capability than the original model.
Sennheiser explains this in a much more eloquent way though, claiming that the “Sennheiser HD 660S2 offers listeners what they requested most from the headphones’ predecessor. 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.”

This more dynamic listen uses “enhanced sub-bass tuning” thanks to improved transducer airflow and a refined voice coil as part of the design. But, crucially, this more capable low-end output doesn’t overbear any of the other all-important frequencies, delivering a supposedly warmer overall sound profile.
And how much will you need to pay for the pleasure of buying a pair of Sennheiser HD 660S2 open-back headphones? Thepre-order page is open now, with £499 being the price in the UK, $599.95 being what you’ll pay in the USA. They’ll be on sale from 21 February.
Considering just how much some open-back headphones cost, that’s not entirely unreasonable – although the previous model can be found for even less if you shop around. You’ll probably want to budget for one of thebest headphones DACsto pair with your new headphones too, if you don’t already have the necessary gear.
