The heart of the closed headphones is a 40mm titanium-coated transducer. The driver enables high-precision mapping of music and speech. In particular, the clear high-frequency range draws every nuance of the music, while the bass range draws drums and effects impressively, without placing them too much in the foreground. Despite the closed construction principle, the Performance 880 presents itself with an airy sound, as you would expect with open headphones. So it combines the advantages of shielding a closed model with an “open” sound that is transmitted over the entire frequency of human hearing. Thanks to the S-Logic Plus technology, the natural spatial sound is aimed for in order to locate instruments with precision.
