Sennheiser HD 660 S: A classic headphone, reimagined


Sennheiser revives a classic design and this is one of those rare moments where some people will prefer the remake to the original

Just like one of the great Hollywood remakes, the HD 660 S has tried to improve on near perfection, and to its credit it has almost succeeded – but as ever, some people will just always prefer the original.

Sennheiser HD 660 S Headphone Review

Sub-bass extension is still not mind-blowing.

I am hearing a new level of clarity from my CD's and FLAC Files - mainly Classical. What more can I say - they are every bit as good as claimed. No problem hooking them up to my Yamaha Amplifier.

I had been looking for some headphones for late night/early morning listening when the family are asleep and wanted to invest in a quality pair to match the rest of my setup. I had read many reviews before deciding to audition a few pairs (mainly...
