＜AKG / K712PRO Open-Back Headphones＞
■Newly Developed High-Performance Driver Unit
The driver incorporates a newly developed high-performance unit and employs AKG's proprietary housing structure. By optimally regulating the airflow within the housing, the driver unit's reproduction capabilities are maximised. It delivers clear, expressive bass – often challenging to reproduce in open-back headphones – while the mid and high frequencies offer AKG's signature delicate, distortion-free, pure and clear sound.
■Overwhelming Immersion: Precise Reproduction Conveying Atmosphere
The immense sonic detail delivers richly immersive sound, as if witnessing a live performance. It conveys the atmosphere and emotion present during recording, showcasing top-tier spatial expression. It meticulously reproduces every intricate sonic nuance without compromise.
■Two-Layer Diaphragm Structure
By designing the diaphragm using two distinct materials, it combines the best properties of each. This suppresses unnecessary vibrations from the diaphragm while accurately reproducing subtle sonic nuances.
■Vari-Motion Technology
Vari-Motion Technology, which varies the diaphragm thickness between the centre and outer edge, sharpens sound contours and achieves distortion-free, clear mid-to-high frequencies. It maintains an exquisite balance between the bass and mid-to-high frequencies.
■Flat Wire Voice Coil
The driver incorporates a flat wire voice coil using ribbon-like wire. This allows the wire to be wound at a high density, resulting in a compact and lightweight moving part that delivers excellent transient response. Combined with a powerful neodymium magnet, sensitivity is enhanced, enabling swift response to even the most delicate audio signals.
■Large-Diameter Ear Pads
The large-diameter ear pads fully enclose the ear, minimising pressure and maintaining comfortable wear even during extended monitoring sessions. The surface features a smooth velour material, offering a soft, premium feel.
Furthermore, the ear pads are removable and hand-washable, ensuring they remain clean for use. Inside the ear pads, low-rebound material conforms to the shape of the temples. This snug, gap-free fit allows you to fully enjoy the premium AKG sound of the K712 PRO.
■Genuine Leather Headband
The headband utilises soft, durable genuine leather. It also incorporates the familiar AKG ‘self-adjusting function’, which automatically adapts to your head size upon wearing.
■Convenient Detachable Cable
The detachable cable design allows for easy replacement should it become damaged. Two types are included: a straight cable and a coiled cable.
