EarAcoustic Audio STA-Pro Series
Advanced Acoustic Technology for Unmatched Sound
The STA series is powered by dual-core dynamic coil acoustic architecture, featuring double energy for superior sound quality. With Tesla-level magnetic coil technology and a bilateral four-unit design, it delivers remarkable analytical precision and a wide dynamic sound field. The 6mm micro coil handles high and ultra-high frequencies, while the 10mm large dynamic coil excels in mid to low frequencies. With a combination of N50 and N50 magnets, the STA series achieves a magnetic flux of approximately 10,000GS, offering a powerful and energetic audio experience.
Precision Engineering for Unmatched Sound Performance
The STA Pro features a 10mm and 6mm dual polymer composite diaphragm, delivering sharp dynamics and rich detail with a smooth, balanced frequency range. It undergoes hundreds of simulation experiments for optimized acoustic performance.
The STA Pro Ultra combines a 10mm nano ultra-thin graphene diaphragm and a 6mm polymer composite diaphragm, offering powerful dynamics and musical detail. The graphene diaphragm’s elastic modulus is approximately 100 GPa, ensuring ultra-fast response.
The STA Pro MAX uses a 10mm liquid crystal polymer (LCP) diaphragm with a 6mm polymer composite diaphragm, delivering a durable sound with rich musical charm. The LCP diaphragm’s elastic modulus is around 100 GPa.
High-End Audio Performance for Exceptional Listening
The STA series boasts a high-end audio-grade target frequency response curve, delivering an ultra-wideband loud field with a range from 10Hz to 30,000Hz. This balanced frequency response enhances the music appreciation experience by revealing richer sound details, making it easy to distinguish the positioning and layering of various instruments and vocals. Designed to reduce auditory fatigue and increase listening endurance, the STA ensures a warm and immersive listening experience, ideal for cycling a single song throughout the day. It accurately reflects the original sound, meeting the professional needs of audio engineers, artists, and producers, allowing them to judge sound quality and achieve precise on-site ear feedback.
The Perfect Fusion of Science and Art in Sound
STA explores the intricate balance between science and art in tuning, selecting dual magnetic units that offer powerful performance and efficient driving force in the mid-to-low frequency range. Paired with a 6mm micro coil dedicated to high frequencies, STA undergoes detailed tuning across more than ten aspects, along with meticulous optimization of dozens of acoustic parameters. With a total harmonic distortion (THD) of <0.5% and intermodulation distortion <0.05%, the result is a pure, natural tone that remains durable and transparent. The STA Series is easy to drive and delivers fast transient response time (<3 milliseconds) and strong low-frequency rebound (≈50 milliseconds). Signal attenuation <0.5dB ensures a delicate and transparent sound.
Premium Surface Finish
The STA-Pro series uses ABS resin material with an electroplated cavity and zinc alloy electroplated frame. The resin process creates a glossy surface, ensuring both durability and a sleek, refined look.
High-Definition Interchangeable Audio Cable
STA comes standard with a high-definition interchangeable audio cable featuring an oxygen-free copper core plated with silver. The cable's delicate, soft texture ensures it is free from entanglement, delivering stable and high-definition music transmission with rich details. It features a 2.5mm single wire diameter and a 0.78mm dual pin design for enhanced connectivity and performance.
