Sennheiser HD 660S2 Headphones With Swappable Cables Unveiled

The Sennheiser HD 660S2 Headphones have been unveiled. The new headphones come with a bigger price tag than Apple’s AirPods Max. This is even more outstanding because the HD 660S2 comes without ANC or wireless functionality.

The Sennheiser 600 series has been a leading product among audio enthusiasts who require a pair of solid cans. The series has gone through several iterations during the 25 years since it debuted. The new HD 660S2 offers excellent sound improvements from its predecessors and comes with a solid build.

The original Sennheiser HD 600 model was priced at $450 when it was released in 1997. That price tag translates to about $850 today and the new model is pretty still affordable. Sennheiser says the revised 300-ohm transducers help to lower the resonant frequency down to 70Hz for hefty kick drums in the headphones.

All the models in the Sennheiser 600 series are open-back headphones that allow some degree of noise interference. The HD 660S2 is designed to leak sound to improve its performance. The HD 660S2 lacks active noise cancellation, so is useful only in quiet environments. They can be terrible when used in the office or in public places. The open-back design also implies that incorporating noise cancellation is not feasible.

The headphones have a pair of 5.8ft swappable cables with 0.25-inch and 4.4mm stereo plugs. The headphones can also be connected with an amp using its 1/8-inch adapter. Connection to an amp helps the user to have the full complement of the device’s capabilities.

The Sennheiser HD 660S2 is designed for those folks who want to enjoy hi-res audio to the fullest without paying a premium amount for it. It does not have any app support and the user is guaranteed unbridled sound output. The headphones could be pre-ordered directly from Sehneisser at $400.
