Illustrative placeholder — we don’t have licensed photography for this product yet.

Research summary

Why it scores 6.8.

The cheapest planar worth owning. Across 1 cited source and 2.680 owner reviews, the HiFiMan HE400se rates strongest on price fairness and performance, and weakest on support & warranty.

Where it falls short

  • Build quality is the weak point — headband and cable both fail
  • HiFiMan's QC and RMA record is poor
  • Needs more power than a phone

Price history

Not enough yet to tell you anything.

2 observations, recorded 28 July 2026. We have 2 observations over 0 days. We need at least 5, spanning at least 14 days, before a range tells you anything. Nothing here is a trend yet.

We have no price feed, so this fills up only when someone re-checks the listings by hand. We would rather show you an empty clock that started than a chart drawn from two points.
Something wrong here?
What we have, what it should be, and how you know.
A link to a measurement, teardown or review. We will not change a score without one — see /methodology.
Only so we can tell you what we did. Nothing else.

Published corrections appear on /revisions with the reason. We may not write back.

No outcome data yet

We ask everyone who buys through us, 6 and 12 months later, whether they still use it. We’ll publish the answer here — including when it’s bad.

No one has told us how this worked out yet. No score on this page is affected by it yet.

Purchases are recorded in this browser, and on the server only until it restarts. There is no mailer yet, so no follow-up will actually arrive. We publish a rate at 30 answers and not before — a percentage from three people is a made-up number.
