The Selected 10mm coaxial dual dynamic is distinguished by its superior sound quality. The bass is rich and comfortable, and the intensity is full; On the other hand, the vocals are naturally magnetic and full of thickness.

The DB3 uses a combination of "1BA+ dual dynamic" for a total of 3 drivers. Comparatively to dynamic headphones, the DB3 focuses much more on details.

The DB3 utilizes a special customized extremely high frequency balanced armature driver unit, which produces pure and clear high frequency signals, enhancing the resolution for more expressive and richer musical instruments.

Aluminum alloys are more stable and have fewer undesirable resonances due to their higher density. The NICEHCK team considers these tiny details to be integral to improving sound quality, even though they are only small.

A combination of zinc alloy face panels and an environmentally friendly PC shell makes the DB3 stand out as a work of art. The Shell is translucent and full of the feeling of reality. The face panel is fixed with three screws, and reeks of technology.

DB3 uses mainstream PCB electronic crossover technology to divide the frequency bands of low, medium, and high accurately. The Synergy between the dual dynamic and the balanced armature enables the DB3 to achieve a tri-frequency far exceeding the price.

The DB3 is tuned by an acoustic engineer with more than 10 years od experience, and spares no effort to purse better sound quality. The low-frequency is comfortable and powerful, the medium-frequency magnetic is full, and the high-frequency sound is clear and pure.
