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.
