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.
