Enjoy music as the artist intended with High-Resolution Audio 

Take your digital music collection to another level with High-Resolution Audio. By capturing music at a higher rate than CD (up to 384kHz/32-bit, rather than 44.1kHz/16-bit), High-Resolution Audio allows you to get closer to the original studio recording and enjoy your music just as the artist intended.

High sensitivity for a loud, clear performance

With a high sensitivity of 108dB/mW, these headphones are highly efficient in converting electricity into acoustic signals. That means you’ll hear a louder sound across the entire audio spectrum (compared to less sensitive headphones) when listening to music through the same source and at the same volume level.

Dual Balanced Armature drivers for robust highs and mids  

Fine-tuned for richer in-ear audio. Light and compact, Balanced Armature drivers are engineered for the precise, efficient reproduction of mid- and high-end frequencies, so every vocal line soars with crystalline clarity. Their linear-drive, T-shape design reduces flex in the armature, reducing sound distortion for sharpness and clarity.

Aluminium Super Tweeter for soaring highs 

Enjoy high-ends that soar with precision and clarity, thanks to a responsive all-aluminium Super Tweeter. One half of the dual Balanced Armature drivers, the Super Tweeter has an aluminium diaphragm that is quick to respond while reducing resonance. The result is pristine, distortion-free high-end notes.

Wide frequency response for a full range of sound

The wideband frequency range – spanning 4Hz to 40kHz – is designed for today’s broad variety of music styles. The 4Hz low end of the frequency range picks up every powerful sub-bass note. At the 40kHz high-end, you’ll be able to enjoy vocal melodies, subtle audio harmonics, and tonality in outstanding clarity, as well as feel sound beyond your natural hearing.

Dual layer cord for balanced listening 

Listen through the supplied dual layer cord for rich, authentic sound. The cord features a central copper wire that’s specifically engineered to deliver clearer high-ends. A layer of silver then covers this wire, making it ideal for producing warm, rich bass. When combined, this ensures you’ll be able to enjoy pristine, balanced sound.
