Featuring an open-back design that delivers an extremely wide, three-dimensional soundstage and ultra-precise sound reproduction, the HD 490 PRO gives you the clarity you need to make your most important decisions. Full-spectrum audio precision: Sennheiser's innovative open-frame architecture improves master clarity and balance, delivering a comprehensive, accurate, and clearly defined audio experience. This advancement significantly aids in identifying and resolving issues related to panning placement and conflicting frequencies, resulting in a more refined final master. Eliminate blind spots in production At the heart of the HD 490 PRO earcups are cutting-edge neodymium magnets and innovative low-frequency cylinders. These components work in sync to produce full, accurate, and clearly defined bass, identifying and resolving those pesky low frequencies that can get in the way of a detailed mix or master.
