What reviewers said
HiFiMAN HE 1000se
The HiFiMAN HE1000se is a high-end planar magnetic headphone that delivers exceptional detail retrieval and a spacious, airy soundstage. Its bright-neutral tuning offers strong bass and treble extension, though the prominent treble can become harsh with lower-quality recordings. While its 35-ohm impedance and 96 dB sensitivity make it moderately easy to drive, it still benefits from quality amplification to perform at its best.
- Pro:Outstanding resolution and micro-detail clarity
- Pro:Wide, airy soundstage with excellent instrument separation
- Pro:Strong extension at both frequency extremes
- Con:Bright, peaky treble can fatigue on poorly mastered tracks
- Con:Requires a decent amp despite moderate sensitivity
- Con:Midrange lacks warmth and body for some tastes
