ARTA is an open-back planar magnetic headphone with a 3 Hz - 115 kHz frequency range, greater than 130 dB SPL maximum output, and very low total harmonic distortion below 0.05%. Its high-impedance design is best suited to experienced listeners and studio users with a powerful desktop amplifier.

★ Ideal for

ARTA suits home-studio users seeking a frequency-response reference headphone because its 3 Hz - 115 kHz range, high linearity, and very low distortion can support detailed monitoring, although its 6000 price and need for powerful amplification make it less affordable than typical studio monitors.
