Our Verdict

Sennheiser HD 660 S

Sennheiser HD 560S

The Sennheiser HD 560S and the Sennheiser HD 660 S are similar-performing open-back, over-ear headphones, with the HD 560S slightly better for most listening applications than the HD 660 S. The HD 560S feel notably more comfortable, but the HD 660 S are better built and come with an extra cable.
