Title

The HIFIMAN EF400 is a desktop DAC/amp combo built around HIFIMAN's own Himalaya R2R DAC and a balanced headphone amplifier stage. It's aimed at listeners who want a single box on the desk instead of a stacked chain, and who specifically want the R2R flavor rather than a conventional delta-sigma chip.

Use it as the anchor of a desk rig: computer in over USB, one pair of hard-to-drive planars out the balanced jack. Since it's balanced, it pairs naturally with HIFIMAN's own planar lineup and any headphone you can get a balanced cable for. If you're currently running a dongle and hitting the wall on volume with full-size cans, this is the step up.

  • Himalaya R2R DAC with balanced headphone amplification
  • All-in-one desktop unit, no separate DAC needed
  • Authorized HIFIMAN 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.
