The HE400se brings HiFiMAN's Stealth Magnet planar drivers down to a genuine entry-level price. You get the planar hallmarks, fast clean bass and an open spacious stage, with a relaxed treble that stays kind to rough recordings.

At 32 ohms and 91 dB it will make sound off almost anything, but it scales: a dongle gets it going, a modest desktop amp gets it upright. Open-back means the room hears it too, so treat it as a home pair rather than an office one. Still the standard answer to "what should my first planar be?"

  • Stealth Magnet planar drivers, open-back
  • 32Ω / 91 dB sensitivity
  • Best paired with a desktop amp or capable dongle
  • Authorized retailer, 1-year warranty

Frequently asked questions

Is this unit genuine?

Yes. TonePier is an authorized retailer — every unit comes from the brand or its official distributor, carries a valid serial number and is covered by the full manufacturer warranty.

How long does shipping take?

SKUs stocked in our US warehouse ship within 1–2 business days. Items shipped direct from our China hub typically arrive in 8–15 days with full tracking. The product page tells you which applies before you order.

What if it isn't for me?

You get 45 days to decide. Keep the packaging, keep it in like-new condition, and send it back for a refund. Ear tips unsealed for hygiene reasons are fine — we expect you to actually listen.
