Sennheiser has launched the HD 620S, its latest pair of headphones that try to balance performance, noise isolation, and comfort.
This model is a bit of an odd duck but in a good way. The line that it’s a part of, the HD 600 series, consists entirely of open-back headphones. These are great at outputting high-quality audio. However, they're not so good at blocking outside noise, making them a poor fit for travel. The HD 620S is swimming against the current by being a pair of closed-back headphones. Devices with this design are much better at stopping noise from leaking in.
