What is Hi-Res Audio?
- The goal of a High Resolution Audio system is to playback audio files without degrading quality, as the signal passes along the audio chain, through the electronics and speaker or headphones.
- High resolution audio files originated in the music recording industry and have a higher bit depth and sampling rate than 16bit / 44.1kHz CD file format.
- Covers a wider frequency range and wider dynamic range, stretching beyond the limits of our hearing.
- The Japan Audio Society and the Consumer Electronics Association have defined a standard set of requirements for High Resolution Audio systems, and only products meeting those requirements are eligible for the Hi-Res logo.

50 millimeter high power drivers
Each speaker is carefully handpicked, tuned and tested, and is being paired for the most detailed natural sound. The 50 millimeter drivers utilize high power neodymium magnets to reproduce all your music’s dynamics and deliver well balanced crisp bass, transparent mid-range and pristine high frequencies.

Acoustic open back design
An acoustic open-back architecture eliminates air pressure build-up behind the driver, allowing the diaphragm ample free movement, greatly enhancing sound transparency and smoothening extended high frequencies.

Layered motion control
Layered Motion Control (LMC) drivers feature a multi-layered polymer diaphragm that encases a layer of damping gel. These layers form a flexible boundary and – together with the gel – absorbs and dampens any exaggerated frequencies, resulting in a smooth and flatter frequency response. The result is a more balanced, natural and refined range of high frequency sounds.

Memory foam earpads
The materials used for the Fidelio X2 are carefully selected to ensure long-wearing comfort and enhanced sound performance. Deluxe breathable ear pads with memory foam are designed for optimal ergonomic fit. Not only does the foam mould itself perfectly to the shape of your ear, it also seals in bass sounds while keeping out ambient noise.
