Moondrop has introduced the Moondrop Harmon wired in-ear headphones, the housings of which were developed jointly with HeyGears, a leading brand in the field of 3D printing. So, DLP-3D printing technology is responsible for the perfect fit of the headphones.
Moondrop Harmon is equipped with three dynamic drivers with an advanced XTM crossover, as well as a sound tuning system with four acoustic chambers. The design of the Moondrop Harmon headphones uses three dynamic drivers with a diameter of 10 mm - a dual composite system of 10 mm drivers in the H.O.D.D.U.S (Horizontally Opposed Dual Dynamic Driver System) format is responsible for the bass and the third 10 mm driver works at midrange / high frequencies.
The headphones use a four-chamber tuning system, the final version of which was created using state-of-the-art FEA simulation - the result is a dual composite isobaric configuration of 10 mm drivers arranged in parallel in a horizontal plane.
The 10 mm mid-high frequency driver uses a composite diaphragm with a glass dome and flexible suspension, which is produced using specialized glass molding technology. This micron-thick diaphragm is characterized by high rigidity and improved damping while maintaining an ultra-lightweight design.
The headphones are supplied with a high-purity copper cable with 2-pin 0.78 mm connectors and a replaceable plug system. Included in the package are a mini-jack 3.5 mm and a balanced Pentaconn 4.4 mm connector. Moondrop Harmon in-ear headphones are available for sale at a suggested retail price of $349.99.
