EarAcoustic STA Pro delivers high-fidelity sound through its dual dynamic driver setup. A 10mm ultra-clear analysis composite diaphragm for powerful lows and mids paired with a 6mm composite diaphragm for precise highs. Tesla-level N50 magnets generate ~10,000GS flux density, ensuring sharp dynamics, ultra-low distortion and rapid transients under 3ms with strong bass rebound around 50ms. This creates a smooth and balanced profile with wide soundstage, rich details and clear instrument separation. The balanced sound profile reduces listening fatigue and immerses the listener. A premium 0.78mm 2-pin OFC/silver-plated mixed-weave cable is also included in the package. This cable is built professionally with audiophile-grade materials and the build emphasizes pure-sonic performance with zero microphonics.
