Sennheiser HD 490 PRO | Open-back Studio Monitoring Headphones for Modern Music Production
Professional Open-back Monitoring Headphones Designed for Precise Mixing and Mastering

The Sennheiser HD 490 PRO is a professional open-back monitoring headphone from Sennheiser, featuring an open-back architecture and neodymium drivers, offering a wide frequency response of 5Hz - 36,100Hz (-10 dB). These studio headphones, designed specifically for modern music production, mixing, and mastering, aim to deliver an extremely neutral, uncolored sound, allowing for the most precise judgments. Combining excellent ergonomics with the included dearVR MIX-SE spatial simulation plugin, they bring unparalleled clarity and comfort to professional audio engineers.
Compared to traditional monitoring headphones that offer only a single acoustic characteristic, the Sennheiser HD 490 PRO achieves high flexibility by providing two sets of interchangeable ear pads (for mixing and for producers), allowing for two different monitoring perspectives on a single pair of headphones, making the precise mixing workflow more comprehensive.
