A budget planar magnetic headphone that redefines what is possible at its price, delivering the speed, detail, and low distortion of planar technology with stealth magnets derived from flagship designs.
The HE400se is a watershed moment for entry-level monitoring, bringing the technical prowess of planar magnetic drivers to a price point once dominated by basic dynamic cans. By incorporating trickle-down 'Stealth Magnet' technology, HiFiMAN has achieved a level of transparency and transient speed that is frankly startling for around $100. The frequency response is impressively linear; the bass is tight and extends deep without bloating, while the mids remain clear for vocal tracking and critical EQ work.
Ergonomically, the padded headband is a significant improvement over older budget designs, though the 390g weight might fatigue some users during marathon mixing sessions. The biggest trade-off is power requirements. Despite the low impedance, the 91dB sensitivity means a standard laptop jack won't cut it"you'll need a dedicated headphone amp to reveal its full dynamic range and avoid a thin, compressed sound. Additionally, the included cable is notoriously stiff and feels like a budget afterthought.
For the home studio producer or the budding audiophile, this is the ultimate gateway drug. It offers a surgical perspective on audio that dynamic drivers in this bracket simply can't match. While it lacks the ultimate 'slam' of high-end models, its value-to-performance ratio is currently unrivaled in the open-back market.
