Sennheiser HD 620S Over-ear

Airy, spacious sound ; Detailed, smooth and easy-going presentation ; Sturdy build

Could do with a greater dose of punch and dynamics ; Some might find the clamping force too firm

Sennheiser’s first closed-back HD 600 headphones do the range proud with their eminently relaxed, airy and easy-listening performance

Wide, open sound for a closed-back headphone ; Ample bass presence and precise high-end ; Thick padding counters strong clamping force

Design borrowed from lower-tier range ; Not everyone will appreciate the extra bass ; Not as portable as some rivals

A closed-back take on a well-regarded pair of wired headphones. The Sennheiser HD 620S gets the tonality right, without skimping on bass presence – but it’s not perfect, and the styling doesn’t match other 600-series cans.

Much improved sub-bass presence ; Most comfortable pads on a HD6 Series headphones to date ; Easy enough to pair with a wide range of amplifiers

No balanced cable included ; Some flex noise in the housing
