Planar Magnetics like you’ve never seen before: Many headphone companies have tried their hand at Planar magnetic drivers, but none have done it quite like hifiman. Its driver technology has landed them in Time, Forbes, CNET, and CES Editors’ Choice Award Extremely versatile: A pair of high-efficiency, open-back Planar Magnetics that don’t need a fancy amp to sound amazing. Listen to them directly from your phone, laptop, or desktop computer, or add a headphone amp to take them to the next level Dual-sided magnet array: For uncompromising responsiveness and sensitivity, we implemented a dual-sided magnet driver array that uses magnets on both sides of the diaphragm membrane to generate sound waves. Premium aesthetic, Comfortable feel: Like the HE4XX, the HE-X4 retains the fan-favorite: large earcups, plush earpads, and lightweight build. An updated headband provides increased durability and strength for uncompromsing comfort. IMPROVED SENSITIVITY: On the sonic side, dual-sided magnet arrays similar to that of the HE5XX help the HE-X4 achieve improved sensitivity over the HE4XX—with a distinctly warm and subtly dark tone all its own.
