Sennheiser is celebrating its 75th company anniversary this year — and it shows! Over the past few months, we've been shining the spotlight on the manufacturer for several reasons. The celebrations will round off with the stunning HD 560S. These over-ear headphones build on the marvel of the HD 660 S, and are in terms of their price/performance ratio, are a fantastic achievement. They offer a lot in terms of sound with their open design. We keenly placed our order for the HD 560S, and we're more than happy to include this model in our demonstration.
