Superlux HD668B semi-open headphone

Semi-open studio headphone

The Superlux HD668B is a semi-open dynamic headphone built for critical listening in recording studios and home setups. Its design targets engineers, musicians and audiophiles who need accurate sound reproduction across all music genres. Patented construction ensures long-term durability while the lightweight headband and optimised pressure deliver comfort during extended sessions.

Sound signature under sustained use

The drivers produce natural, spatial audio with silvery, clear cymbals and pleasantly natural trebles. Strings and wind instruments render unobtrusively, while bass remains balanced, contoured and deep without becoming boomy over time. Voice reproduction stays exceedingly authentic, maintaining detail and tonal accuracy even after hours of continuous monitoring.

Wired connectivity and cable options

Two detachable straight cables are included: a 1 metre lead for portable sources and a 3 metre lead for studio monitoring. Both cables can be joined together to extend reach when the workspace demands it. The wired analogue connection avoids latency and compression, limiting the system only by the source device's output quality and cable length.
