Our Verdict

Philips Fidelio X2HR

HiFiMan HE400se

The Philips Fidelio X2HR and the HiFiMan HE400se are comparable audiophile headphones. Both headphones are comfortable and well-built, with sound profiles that lack low bass but feature detailed mids and inconsistent highs. However, the HiFiMan are planar magnetics with a more immersive passive soundstage. Due to fit, positioning, and seal, they're also less sensitive to deviations in bass and treble delivery.
