DUNU EST 112 2 EST + 1BA + 1 Dynamic Driver Hybrid MMCX HiFi Audiophile In-ear Earphone
Material and design, everything is just right

The aerospace aluminum alloy five-axis CNC cuts a light and firm cavity, the stainless steel art panel is polished to be exquisite and shiny, the gentle and natural shape curve erases all the edges and corners, and the delicate matte transfers the wonderful touch from the fingertips to the heart.

Complex metal craftsmanship, pleasing design aesthetics

Each panel is meticulously carved, after several times of cutting, shaping, polishing, etching, sandblasting, cleaning, electroplating...just like handicrafts, it is beautiful and delicious.

Electrostatic, dynamic, balanced armature, one-time possession, one ear

DUNU's first Electrostatic, dynamic, and balanced armature hybrid earphones are integrated with three high-performance sound units. The superior structure is supplemented by precise adjustments, and the sound of the heavens blooms between square inches.

The air is within reach this time

The second-generation Sonion custom in-ear electrostatic unit, far exceeding the ultra-high frequency response of the balanced armature and the dynamic unit, is crystal clear, silky and stretched, and full of air. This time it is within reach.

Limited space can also create infinite possibilities

The white eartips are the official standard eartips. The sound is balanced and accurately restored, which is suitable for most music types.

Gray eartips are transparent eartips, which enhance high-frequency performance and enhance sound transparency. They are suitable for expressing female voices and some stringed instruments.

The black sponge cover is a memory foam soundproof cover, which improves the sound insulation performance, and the sound is smooth and full. It is suitable for eliminating some stimulating sound source burrs.

*The memory foam eartips need to be kneaded tightly before use, and then quickly placed in the ear canal to adjust to a comfortable position. The best effect can be achieved after the self-adaptive rebound filling.
