The HD HD669 are closed-back, circumaural headphones designed for professional monitoring applications. Although suitable for a very wide range of applications, the exceptional attenuation of external noise makes the HD 669 particularly useful for use in a high-noise environment. The balanced, high definition and clarity sound of the HD-669 assures that a professional sound engineer can have full confidence when recording or monitoring. Its patented sturdy headband structure provides long-lasting durability even in challenging conditions, yet its light weight and optimized mechanical pressure provides long-term wearing comfort. The HD669 comes equipped with 2 detachable straight cables:
The short cable is 1 meter long for personal sound source on-the-move applications and the long cable is 3 meters long for professional monitoring applications. These cables can be connected together for even more distance if desired. Included cable clip can secure detachable cable from pulling out by incident.
