Highlights
Exceptional performance
The Philips Fidelio X3 headphones boast doublelayered ear shells that reduce resonance and
vibration. The neodymium drivers are
engineered to tilt at 15 degrees, fitting the
natural geometry of your ear for optimal
accuracy at high frequencies. The result: flawless
performance, with exquisite detail.
Feel the passion
Air is able to flow freely through the fabriceliminating air pressure build-up behind the
diaphragm and creating immersive, spacious
sound.
The art of balance.
The 50 mm acoustic drivers boast diaphragms
composed of multiple polymer layers, and filled
with damping gel. The flexibility and smoothness
of each diaphragm delivers perfectly balanced
sound. The bass is impactful without being
overpowering. Midrange frequencies are full and
smooth. High frequencies are exquisitely
detailed.
Transparent Kvadrat fabric
The clean, elegant design of these premium
over-ear headphones beautifully updates their
predecessor-the legendary Fidelio X2. The dark
satin finish of the metal frame seems to float
over the durable, black Kvadrat fabric that
covers the ear cups.
Responsibly sourced
These over-ear headphones aren't just built to
sound spectacular: they feel incredible too. The
light, soft inner headband adjusts to fit perfectly.
The outer headband adds a reassuring weight,
while the snug fit of the feather-light memory
foam ear-cup cushions creates a perfect seal.
Ideal for long listening sessions.
Open-back design
The open-back ear-cup design is covered with
acoustically transparent Kvadrat speaker fabric.
Hi-Res Audio.
Twinkling pianos. Blistering rock. Whatever you
love, these Hi-Res Audio headphones let you
feel the full impact of every note. When wired to
a high-resolution source, you’ll get the full
benefit of lossless audio that’s recorded at a
higher sample rate than CDs—for a brilliantly
lifelike performance.
The black Muirhead Scottish leather that covers
the outer and inner headband is sustainably and
ethically sourced. Beautifully soft and textured,
this high-performance leather lends a
sophisticated touch to the headphones.
Authentic sound
Immerse in your favorite albums—ho
like to listen. The included cable boasts a 6.3–3.5
mm jack adapter, so you can listen on your
smart device as well as your home setup.
