EarAcoustic STA Pro

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.
