Warranty Model Professional Official AKG Professional Air Monitor Headphones K240 STUDIO Limited Edition Japan Exclusive Model with Original Sticker

The "K240 STUDIO Limited Edition" is a professional studio headphone based on the "K240" series, which has been a long-time favorite in music production studios around the world. Since its introduction in 1975, the K240 has been a staple in recording and mixing, contributing to the creation of numerous classic albums. Its track record of being used in historical works, including Quincy Jones' "We Are the World," proves the reliability and high sound quality of the K240. ■Wide Dynamic Range with XXL Transducers Equipped with AKG's proprietary large driver, the "XXL Transducer." This achieves balanced reproduction from low to high frequencies, enabling accurate monitoring required in production environments. Rich bass and clear treble faithfully reproduce even the smallest details of the music. ■ Precise sound quality control with VariMotion Technology The diaphragm employing the patented "VariMotion Technology" has a structure that changes the thickness between the center and the outer edge, suppressing partial vibrations. This allows for a balance between the delicate nuances of the high frequencies, the power of the low frequencies, and the transparency of the mid frequencies. As a result, the sound localization and depth are reproduced with extreme accuracy, dramatically improving the quality of mixing and recording. ■TWO-LAYER diaphragm for clear and crisp mid-to-high frequency reproduction This diaphragm is made by combining and bonding thin films made from two materials with different vibration damping characteristics. It achieves high damping performance, attenuating unnecessary vibrations that cannot be completely eliminated by ordinary diaphragms. This results in clear and crisp mid-to-high frequency reproduction. ■Natural sound thanks to semi-open air structure: By combining the advantages of closed and open-type headphones, the semi-open air design achieves a natural sound without a feeling of confinement. It maintains a comfortable fit even during long work sessions. ■Specifications Structure…Semi-open air type Sensitivity (1kHz)…91dB SPL/mW Frequency response…15Hz～25kHz Maximum input power…200mW Impedance…55Ω Ear pads…Around-ear, detachable, synthetic leather Input connector…3.5mm stereo mini plug (gold plated) Cable…Detachable, single-sided Weight…230g (excluding cable) Accessories…EK300 (headphone cable (3m straight, OFC)), standard plug adapter (screw-type, gold plated) The "K240 STUDIO Limited Edition" is a professional studio headphone based on the "K240" series, which has been a long-time favorite in music production studios around the world.
