From the singer’s breath to fingers squeaking on a fretboard, the Philips Fidelio open-back headphones match feather-light comfort with pristine tuning. Discover new layers of transparency and detail every time you slip them on.

Engineered For Exceptional Performance

The Philips Fidelio X3 headphones boast double-layered 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.

Premium Design

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. Air is able to flow freely through the fabric-eliminating air pressure build-up behind the diaphragm and creating immersive, spacious sound.

50 mm Drivers

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.

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.

Acoustically 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.

Sumptuous Muirhead Leather

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 from Any Source

Immerse in your favorite albums however you like to listen. The included cable boasts a 6.3 to 3.5 mm jack adapter, so you can listen on your smart device as well as your home setup.
