The Austrian Audio Hi-X65 Professional Open-Back Over-Ear Headphones are designed for critical listening applications in audio production and demanding hi-fi environments. These headphones feature a 44 mm driver with High Excursion technology, utilizing a ring system with a strong magnetic field for improved airflow and precise diaphragm control. The open design allows for a natural, spatial sound with exceptional clarity in instrument placement and audio detail reproduction. The construction with a copper-coated aluminum voice coil reduces diaphragm weight for faster response times and minimized unwanted resonances. The Hi-X65 headphones offer high-resolution sound accuracy for mixing, mastering, and detailed music enjoyment. With a height of approximately 21 cm, adjustable headband, and adjustable ear pads, they enable comfortable long-term use. The over-ear design with soft ear pads provides effective sound insulation while maintaining the acoustic properties of the open design. Weighing about 350 g, they combine durability with comfort. All components are made in Austria from high-quality materials, reflecting the brand's tradition in professional audio technology. The matte black finish and robust construction ensure long-term reliability in studio and home listening environments. The connection is made via a detachable 3 m cable with 3.5 mm and 6.3 mm adapter options for versatile connectivity to audio interfaces, mixers, and high-fidelity audio systems. The Hi-X65 model represents the successor in Austrian Audio's professional headphone series, building on decades of audio engineering expertise to provide precise monitoring capabilities for audio professionals and discerning listeners who value accurate sound reproduction.
