★ Professional headphones that combine elegant, beautiful appearance with high-quality sound The unique open-air design, developed through years of research and development, delivers exceptional reproduction of mid- and high-frequency sounds, carefully reproducing every single sound and even reverberation. - By adopting a "flat wire voice coil" that uses ribbon-shaped wire, we have succeeded in making the voice coil smaller and lighter. It achieves excellent transient characteristics, responding quickly to even the most minute electrical signals, and the small gap between the magnet and voice coil improves sensitivity. - The diaphragm uses a "TWO-LAYER diaphragm" structure that combines two types of material and "Varimotion Technology" that changes the thickness at the center and outer edge. While maintaining high-frequency characteristics, the damper characteristics have been improved and split vibrations have been suppressed. - The ergonomically designed 3D foam ear pads provide a gentle and secure fit. Made from smooth velour material, it is comfortable to wear for long periods of time. - Features a self-adjusting function that allows you to adjust the length of the headband just by putting it on. - The ear pads are removable and can be easily replaced. [AKG headphones' unique technology] ■Varimotion Technology: A technology that appropriately controls the movement of the diaphragm by changing the thickness of the diaphragm at the center and outer edge. The thick central "SOUND ZONE" suppresses the split vibrations that cause distortion, resulting in extremely clear high frequencies. In addition, the thin outer edge of the "MOVEMENT ZONE" supports the smooth movement of the "SOUND ZONE" when high frequencies are output. When outputting low frequencies, it works together with the ``SOUND ZONE'' to act like a large diaphragm, producing powerful sound. ■TWO-LAYER diaphragm A diaphragm made by combining and bonding together thin films made from two materials with different vibration damping characteristics. It has high damping (braking) performance, and attenuates unnecessary vibrations that cannot be completely eliminated by ordinary diaphragms. Delivers clear and crisp mid-to-high range reproduction. ■Specifications Structure: Open-air type Sensitivity (1kHz): 93dB SPL/mW Frequency response: 10Hz to 39.8kHz Maximum allowable input: 200mW Impedance 62Ω Detachable around-ear ear pads, made of velour Input connector Standard plug (gold plated) Cable: 3m straight, single-sided, weight: 290g (excluding cable) Accessories: 3.5mm stereo mini plug adapter (snap-on, gold-plated)
