Specification AgeRangeDescription : Adult AudioDriverType : dynamic_driver Brand : Moondrop BulletPoint1 : Closed-back Headphones for Professional Monitoring: The Joker was designed to meet the stringent monitoring requirements of professional recording studios. It delivers precise sound reproduction and avoids the inaccurate timbre and veiled details of traditional professional monitoring closed-back headphones. The Joker's replaceable cable/ear-pads make it easier to modify and maintain. BulletPoint2 : High-performance 50mm Dynamic Driver: The first generation of 50mm dynamic drivers independently developed by MOONDROP is based on a magnetic circuit architecture optimized through FEA (Finite Element Analysis), and the large size alloy-coated dome diaphragm provides a solid hardware foundation for high-quality audio monitring. BulletPoint3 : Asymmetric Brass Acoustic Cavity, Multiple Anti-Standing-Wave Design (Closed-back Headphone Breakthrough) : To overcome common acoustic problems caused by cavity standing waves in closed-back dynamic driver headphones, MOONDROP took as a reference point the structure of the legendary MDR-R10 closed back dynamic-driver headphone. BulletPoint4 : Superior Workmanship: The exterior of the brass acoustic cavity is coated with a special black paint finish that will develop a unique and beautiful patina from repeated use and polishing. A special abrasive pad is provided for users wishing to create their own original finish. Please note that abrasive polishing will void the return/replacement warranty. BulletPoint5 : Interchangeable Cable Design, Multiple Use Scenarios: The Joker uses standard dual 3. 5mm headphone jacks to permit easy cable swapping for a variety of usage scenarios such as studio monitoring, professional mixing, and even audio-visual entertainment. *Shipped with a 3.5mm plug headphone cable.
