★Open-air headphones that carefully reproduce even the subtlest audio signals. ◎The unique open-air design, developed through years of research and development, achieves outstanding reproduction of mid- and high-range sounds, carefully depicting each and every sound and reproducing even the reverberation without any loss. ◎By adopting a "flat wire voice coil" using ribbon-shaped wire, we have succeeded in making the voice coil smaller and lighter. It achieves excellent transient characteristics and responds quickly to even the most minute electrical signals. The gap between the magnet and voice coil can be made smaller, improving sensitivity. The diaphragm is a "two-layer diaphragm" made of two different materials, and employs our unique "Varimotion Technology" that varies the thickness between the center and outer edge. This improves damping characteristics and suppresses split vibrations while maintaining high-frequency characteristics. ◎ Ergonomically designed 3D foam ear pads. Made with memory foam for a gentle, secure fit. Made of smooth velour for comfort even when worn 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 cable and ear pads are detachable and can be easily replaced. VariMotion Technology, a technology exclusive to AKG headphones, optimally controls diaphragm movement by varying the thickness of the diaphragm's center and outer edges. The thick "SOUND ZONE" in the center suppresses distortion-causing split vibrations, resulting in extremely clear high frequencies. The thin "MOVEMENT ZONE" on the outer edge supports smooth movement of the "SOUND ZONE" when outputting high frequencies. When outputting low frequencies, it works together with the "SOUND ZONE" to operate like a large diaphragm, producing powerful sound. Installed models: K712 PRO-Y3, K701-Y3, K702-Y3, K612 PRO-Y3, K240 MKII-Y3, K240 STUDIO-Y3, K271 MKII-Y3 Two-Layer Diaphragm: This diaphragm is made by combining and bonding together thin films made from two materials with different vibration damping characteristics. It achieves high damping performance, attenuating unnecessary vibrations that cannot be completely eliminated with a normal diaphragm, resulting in clear, crisp reproduction of the mid- and high-range frequencies.
