Hifiman HE-1000 V4

The HE1000 V4 Planar Magnetic Open-Back Headphones from Hifiman have been updated from their previous model HE1000 headphones and offer redesigned earpads that are thick with an asymmetrical shape, a stronger cable, and polyester earpad surfaces instead of velour material to increase sound transparency for use in the home, studio, with portable devices, and more.

Featuring diaphragms so thin they are measured in nanometer thickness, the result is a pair of headphones that have a frequency response of 8 Hz to 65 kHz and an impedance of 32 Ohms. Their updated headband design will accommodate a wider range of head sizes. Their planar driver is the cornerstone of their remarkable sound.

The headphones have an updated earcup design that is trimmed down in size for a slimmer, sleeker look; they are now 11mm in thickness, a significant reduction in size from the original model's 14mm measurement. The earpads have become thicker with an asymmetrical shape that follows the form of the earcups. They are supplied with a cable that is made stronger with the improved materials of crystalline copper and crystalline silver wire, and built with a wide frequency range, low signal loss, and enhanced emphasis on their low-end for quality audio reproduction. A single-ended 1/4" cable is included along with a balanced 4-pin XLR cable.
