Superlux HD668B Headphones Review

Superlux is a Taiwanese manufacturer of audio components that targets the “affordable market”. Their headphones have slowly entered the market during the past years and they have made quiet a hype in various enthusiast forums and gaming communities. At first, we were quite skeptical about the relatively unknown company as it is the first time we ever heard from them, and at such a low price, the Superlux HD 668B Headphones are the most affordable set of headphones that Benchmark Reviews has ever taken a close look at.
But it was this skepticism that along with our curiosity really set eyes and ears into these headphones. In this review we really wanted to uncover what the Superlux HD668B Headphones had to offer, and evaluate if they are capable enough to provide an enjoyable sound experience. To our surprise they have re-defined our concept of value headphones as they breezed through our tests.
A first glance revealed what seemed as the evil twin of the Audio Technica ATH-700X thanks to the peculiar headband design that features the “self adjusting wing support”. In contrast, a look at the spec sheet found on the back of the packaging in which the Superlux 668B Headphones come reveal a completely different product:
