EarAcoustic Audio STA Hi-End Series
Advanced Acoustic Engineering for Exceptional Sound
The STA series is built with cutting-edge dual-core dynamic coil technology, featuring Tesla-level magnetic coils for superior energy and performance. With a four-unit bilateral configuration, it delivers stunning analytical clarity and a vast dynamic soundstage. The 6mm micro coil handles high to ultra-high frequencies, while the 10mm large dynamic coil excels in mid-low frequencies. Equipped with an N50+N50 magnet system, it ensures double the driving force and a magnetic flux of approximately 10,000 GS, providing a robust sense of energy and unmatched sound quality.
STA-Hi End: High-Performance Transient Sound
The STA-Hi End features a 10mm ultra-rigid beryllium-plated diaphragm and a 6mm polymer composite diaphragm, using a dual-diaphragm design. This combination provides outstanding transient response and a balanced frequency range. The beryllium plating has an elastic modulus of around 300 GPa, allowing for a quick response to audio signals.
STA-Hi End MAX: Advanced Durability and Response
The STA-Hi End MAX is equipped with a 10mm DLC (diamond-like carbon) diaphragm and a 6mm polymer composite diaphragm, utilizing a dual dynamic coil design. The DLC diaphragm has an elastic modulus of around 400 GPa, offering fast signal response and a smooth frequency range.
Precision Engineering for Unmatched Audio Experience
The STA has undergone hundreds of rigorous and meticulous directional simulation experiments to design a standardized acoustic volume cavity structure. This ensures stunning resonance with musical emotions through rational verification. With a high-end audio-grade target frequency response curve, the STA delivers a warm listening experience that is truly irreplaceable. It covers an ultra-wide frequency range from 10Hz to 30,000Hz, offering an expansive loud field, and is capable of cycling a single song throughout the day.
Bridging Science and Art in Audio Tuning
STA explores the concepts of science and art in its tuning process. By selecting dual magnetic units for strong performance and efficient driving force in the mid to low-frequency range, paired with a 6mm micro coil for the high-frequency range, the tuning is carefully optimized across more than ten aspects. Dozens of acoustic parameters are meticulously refined to achieve an exceptional sound quality.
THD < 0.5%: Pure and natural tone
Sensitivity > 110 dB/mW: Easy to drive
Intermodulation distortion < 0.05%: Pure and durable tone
Transient response time < 3 milliseconds: Fast and clear rhythm
Low-frequency rebound ≈ 50 milliseconds: Strong and obvious sense of rhythm
Signal attenuation < 0.5dB: Transparent and delicate sound
Premium Surface Finish
Both the STA-Hi End and STA-Hi End MAX feature a high-quality surface finish designed for durability and aesthetic appeal. The electroplated ABS resin cavity and zinc alloy electroplated frame ensure a robust structure, while the metal-coated resin process delivers a glossy, premium finish that enhances the overall look and feel of the products.
High-Definition Interchangeable Audio Cable
The STA comes standard with a high-definition interchangeable audio cable, featuring an oxygen-free copper core and oxygen-free copper-plated silver wire. The cable offers a delicate, soft texture that is free from entanglement, ensuring stable and high-definition music transmission with rich detail. It has a 2.5mm single wire diameter and a 0.78mm dual-pin design for seamless connectivity.
