Philips Fidelio X3 — Wired Open-Back Over-Ear Headphones, Hi-Res Audio Certified

The Philips Fidelio X3 are wired open-back over-ear headphones designed to deliver a wide, natural soundstage with uncolored audio reproduction for immersive listening. They employ precisely tuned 50 mm multi-layer polymer diaphragms with dampening gel to produce detailed highs, a full, smooth midrange and impactful bass that remains controlled rather than overpowering. Hi-Res Audio certified wired stereo headphones ensure you can hear the full impact of every note when connected to a high-resolution source for lifelike performance. The open-back construction uses acoustically transparent Kvadrat speaker fabric to prevent air pressure build-up behind the diaphragms, resulting in a spacious, immersive presentation. Premium finishing includes responsibly sourced materials — the black Muirhead Scottish leather headband is sustainably and ethically sourced. Ready for both your headphone amp and everyday mobile devices, the Fidelio X3 supports balanced and unbalanced inputs; detachable balanced and unbalanced 3 m oxygen-free cables are included.
