Why you can trust What Hi-Fi?
With the K551s, AKG has taken the Award-winning K550s, added in-line controls, slimmed-down and shortened the cable and included a carry pouch in an attempt to turn them into a portable pair of cans.
While we’re not entirely convinced their sheer size isn’t the first stumbling block in that argument, we certainly have no quarrel with their sound.
A closed-back design with a spacious open-back style performance, the K551s sound expertly balanced – and never boring or flat.
They convey every last detail of any genre you throw at them, with top-notch timing ensuring an upfront, exciting listen wherever you are.
