The HD668B is a semi-open, dynamic headphone whose sound quality meets the demands of even professional recording studios. Its patented sturdy construction provides long-lasting durability even in challenging conditions, yet the headband’s light weight and optimized mechanical pressure provides long-term wearing comfort. The HD668B comes equipped with 2 detachable straight cables: the short one is 1 meter long for personal sound source on-the-move applications and the long one is 3 meters long for professional monitoring applications. Both cables can be connected together for even more distance if desired.
