Our Top Picks
Best planar under $300: more refined treble and imaging than the HE400SE. Needs a proper amp.
Cheapest planar worth owning. Leaves budget for the amp it needs.
The budget desktop DAC/amp to pair with either headphone.
How these were chosen: amperheads does not own or test headphones. Picks follow manufacturer specs, power math, published measurements and dated owner consensus from r/headphones and Head-Fi.
Why Planar Magnetic?
A planar uses a thin membrane between magnet arrays, driven across its whole surface rather than by a single voice coil. In published measurements that usually shows up as:
- Low bass distortion and sub-bass extension that budget dynamic headphones roll off
- Fast transients, which owners describe as clean percussion and plucked strings
The costs: planars are power-hungry, heavier, and almost always open-back at this price.
Comparison
| Headphone | Price (Oct 2026) | Impedance | Sensitivity | Amp needed | Best for |
|---|---|---|---|---|---|
| HiFiMAN Sundara | varies, well under $300 | 37 Ω | ~94 dB/mW | Magni (Unity) or better | Serious listening, all genres |
| HiFiMAN HE400SE | ~$150 list | 25 Ω | ~91 dB/mW | Magni (Unity) or K11 R2R | Budget planar, bass-forward music |
Best Under $300: HiFiMAN Sundara
See today's price for the HiFiMAN Sundara on Amazon ↗The Sundara launched at $499 and has been revised since (HiFiMAN’s later version has improved pads and cable). In 2026 it has sold well below that at US retailers, so check the button for the live price.
Owner consensus and published measurements describe more even treble than HiFiMAN’s cheaper models, good imaging, and deep, textured bass. It is inefficient, so budget for a desktop amp: the Sundara amp guide has the current math. More in the Sundara review .
Who should not buy it: anyone without an amp, or with a small head.
Best Budget Planar: HiFiMAN HE400SE
See today's price for the HiFiMAN HE400SE on Amazon ↗About $150 list in 2026 (it launched at $149), with B-stock units sometimes much cheaper. Owners describe extended, fast bass, slightly thin upper bass/lower mids and a treble peak that can sound bright on some recordings. The cups are wide. Pair with a current amp from about $119 up; see the HE400SE amp guide , the HE400SE review and HE400SE vs Sundara .
No Longer Available: Drop HE4XX
The HE4XX was a Drop exclusive and disappeared with Drop on March 31, 2026. Earlier versions of this page recommended it. Used units appear on the classifieds; otherwise buy the HE400SE or Sundara.
Amps That Drive Planars (Current Models, October 2026)
| Amp | Price | Notes |

| FiiO K11 R2R | ~$170 | DAC and amp in one |
| Topping DX5 II | ~$299 | More headroom; DAC built in |
| Schiit Asgard X | $399 | Separate amp for a bigger upgrade path |

The Magni Heresy and Asgard 3 that older versions of this page named have been retired by Schiit.
Stepping Above $300
The usual next planars are the HiFiMAN Edition XS See today's price for the HiFiMAN Edition XS on Amazon ↗ and FiiO’s brand-new FT15 (launched September 17, 2026 at $499). The FT15 is too new for settled owner consensus. See best headphones under $500 .
What to Avoid
- Running planars straight from a phone: loud enough, but thin bass and compressed dynamics.
- Very cheap combo dongles for the Sundara: they drive the HE400SE adequately but leave the Sundara short of current.
- Expecting a closed-back planar at this price: almost every planar under $300 is open-back. HiFiMAN has shown a Sundara Closed-Back, but we could not confirm US availability.
