Perfection of Sound in a New Version
After nearly a decade, DUNU is back with a refreshed Alpha series, presenting the Alpha 3 as a new benchmark for all lovers of high-quality earbuds. Alpha 3 is a combination of innovative acoustic design, the highest quality materials and masterful workmanship that together create a comprehensive and impressive sound experience.
Advanced Acoustic System
The Alpha 3 heart is a large 14.2mm dynamic transducer equipped with a composite membrane of liquid polymer crystals (Liquid Crystal Polymer) with flexible suspension. This advanced design provides a natural and balanced sound, featuring a high diaphragm stiffness while being flexible to hang, resulting in precise and efficient sound reproduction.
Independent Low Frequency Amplifying Acoustic Chamber
DUNU used an innovative, independent acoustic chamber in Alpha 3 to amplify dynamics and low frequencies, placed in the headphone holder. The central sound tube combined with the rear chamber provides excellent dynamic performance and exceptionally robust bass reproduction.
Surrounding Invisible Multi-Channel Acoustic Holes System
The ventilation system is designed to provide visual discretion while controlling air flow with precision. Acoustic holes placed on the back of the housing cooperate with a large dynamic transducer, guaranteeing impressive sound and high comfort of use.
Stability and Comfort Design
The Alpha 3 housing is made of lightweight aluminum alloy in combination with stainless steel in the acoustic chamber. The housings are characterized by a forward-moving center of gravity, which effectively improves wearing stability and ensures a comfortable fit during long-term use.
Highest Purity Cable
Alpha 3 is equipped with a high-quality cable made of single copper crystals plated with Litz silver. The cable is covered with an insulating layer for efficient and precise signal transmission. The headphones are finished with a 3.5mm standard plug, made in a uniform style with precision-machined metal elements.
Rich Equipment
DUNU joins Alpha 3 with a new, more spacious carrying case that easily accommodates headphones along with three pairs of balanced donut sponge pads and three pairs of versatile low-frequency amplification sponge pads.
Hi-Res Audio Certification
Alpha 3 has been certified by the Hi-Res Audio Japan Audio Society (JAS), confirming its ultra-wide frequency response and ability to clearly reproduce high-quality sound signals.
