Sony MDR-M1 supports high-resolution audio and ultra-wideband playback ranging from 5Hz to 80kHz thanks to its specially designed driver unit that combines soft and hard materials to accurately reproduce low and high frequencies, offering a stunningly accurate and balanced sound performance. Additionally, the tuned port (Beat Response Control) enhances low-frequency response, ensuring tight bass and accurate rhythm by quickly reproducing sudden sound changes. The closed acoustic design provides high sound isolation, eliminating ambient noise and leakage, making these headphones perfect for studio recording and on-the-go mixing. Engineered for comfort and stability, the MDR-M1 ear pads feature thick, low-resilience padding for an airtight fit, while the lightweight design ensures comfort during long sessions. Headphones include two detachable cables, ideal for convenient use in a studio environment, and a 6.3mm plug adapter to ensure compatibility with a wide range of audio equipment.
