Product Description


Founded by Dr. Fang Bian, HiFiMAN today is widely regarded as one of the leading designers and manufacturers of high performance headphones. Their planar magnetic over the ear headphones showcase the sound you would expect from a premium headphone brand.

The key to this unique sound is their specially designed drivers. Planar magnetic drivers do away with the inefficiency of dynamic voice coil drivers. Even and accurate movement of the conductive diaphragm through a magnetic field provides a more natural listening experience not offered by conventional coil driven headphones.

Praised by editors at CNET, as well as the expansive audiophile community the original HE-400 Planar Magnetic Headphones made a lasting impression on the headphone industry. In the spirit of constantly perfecting their craft, HiFiMAN still found room for improvement. The HE-400i takes the highly acclaimed headphones to a new level, with focus on improved comfort for extended listening.

The HE-400i is 30% lighter than its predecessor, with improved efficiency in the construction of the driver. The newly designed headband features an improved pressure pattern, allowing greater comfort during extended listening sessions. The new FocusPad beveled hybrid ear pads are made with pleather and velour, constructed to follow the shape of the ear and improve both comfort and sound quality. With enhanced comfort and efficiency, the new HE-400i Headphones are perfect for those looking to enter the world of planar dynamic audio.
