We’ve long been fond of Sennheiser’s HD 600 range of open-back headphones, which have been impressing us since the late ’90s all the way through to current incarnations, for their wonderfully comfortable design and smooth, very listenable performance.
It’s quite a departure then, for the HD 600 range to introduce a closed-back design, but that’s exactly what the Sennheiser HD 620S headphones are. Sennheiser aims for the new HD 620S headphones to have the airy spaciousness of an open-back design with the privacy and non-leaky advantages of closed-back cans. Does it succeed?
