Giants Beware

Every so often, an affordable product crops up to cries of “Giant killer,” only to fall back down the beanstalk to reality once its true performance is exposed. While a multitude of headphones and speaker systems has fallen victim to this fate, the rare jewel of a true economic emancipator is valued enough to keep on planting those magic beans. In the case of the Superlux HD668B Headphones, the old man wasn’t lying about what these will grow into.

Note: This drop is limited to 55 units. This drop is also limited to members in the US.

Sound Profile

With precise instrument separation, an expansive soundstage courtesy of the semi-open design, and a warm balance across all levels, these headphones accurately transmit your music without adding a hint of fuzz or decay. The bass packs punch without dominating the mix, the mids are sharp and precise, and the highs never approach sibilance, giving you exactly what’s recorded and nothing more.

Additional Details

Anchored by a durable steel wire support, the auto-adjust headrest adapts to the size of your head with no fuss and stays comfortable for hours of play. It may be a little tight at first, but it’ll wear in. Finally, Superlux was kind enough to throw in some enticing extras, most notably two detachable cables, a longer version for home play and a shorter one for the streets. Delivering clear and powerful performance, well-stocked accessories, and minimalist design at a truly giant-slaying price, the Superlux HD668B is the rare Jack that deserves the name.
