The HiFiMan HE400S is one of the most respected entry-level planar magnetic headphones in the audiophile world, offering exceptional sonic performance with a lightweight and comfortable design. Unlike conventional dynamic headphones, the HE400S uses planar magnetic driver technology, where conductive layers are spread across nearly the entire diaphragm surface for more accurate movement, lower distortion, and improved detail retrieval.

Designed to be highly efficient and easy to drive, the HE400S performs well even from smartphones, portable players, laptops, and standard headphone outputs without requiring a powerful dedicated amplifier. Despite its accessible design, it delivers the spacious soundstage, fast transient response, and clean bass performance that planar headphones are known for.

The open-back construction creates an airy and immersive listening experience with natural imaging and instrument separation, making the HE400S ideal for critical music listening, gaming, and home hi-fi setups. Its lightweight build, suspended comfort headband, and soft angled ear pads allow for long listening sessions without fatigue.

The HE400S has become highly regarded among headphone enthusiasts for delivering excellent detail, clarity, and musicality while remaining affordable within the planar magnetic category.
