Review: Sennheiser HD 660S | Classic In Renewed Costume Sennheiser HD 660S

 

Sennheiser's best in the 600 series is the safe choice in this class.

Silky smooth sound rich in details, beautiful vocal reproduction and warm, full sound.

Limited sound pressure and deep bass.

The Senn hoists feel like an old, tailored coat. It may not be ultra-modern or high-tech, but it fits every time you put it on, and the classic ‘Sennheiser sound’ is very addictive. You get sharper dynamics and sharper detail in other headphones, but...

Sennheiser HD 660 S Headphone Review

 

In the audio community, the Sennheiser HD 650 is something of a legend - an excellent value headphon The successor to the legendary HD 650, is the HD 660 S a worthy follow-up?

Crisp and keen treble, much more resolving than HD 650.

Sub-bass extension is still not mind-blowing.

Great sound, great service!

 

I bought this about 2 weeks ago and I'm very happy with it. It pairs very well with the chord mojo. There was a problem with the billing address, I called up and they helped. Always happy with the service at richer sounds.
