Enjoy music as the artist intended with High-Resolution Audio Take your digital music collection to another level with High-Resolution Audio. By converting analog music to digital at a higher rate than CD (24 bit/192 kHz, rather than 16 bit/44.1 kHz), High-Resolution Audio gets you closer to the original studio master recording so you can enjoy your music just as the artist intended. Dynamic HD drivers deliver authentic sound Powerful 1.57 in HD drivers with large vents allow the headphones to deliver punchy, rhythmic bass on even the most demanding track. A light but rigid aluminum-coated liquid crystal polymer diaphragm responds quickly to reproduce vocals and mid-high range notes with intense clarity. Turn up the volume and hear clear, precise sound across the spectrum. Wide frequency response for a full range of sound The wide frequency range - spanning 3 Hz to 100 kHz - is designed for today's broad variety of music styles. The 3 Hz low end of the frequency range offers more than enough latitude for even the deepest sub-bass notes. At the 100 kHz high-end, you'll be able to enjoy vocal melodies, subtle audio harmonics and tonality, giving your music more life and realism. High sensitivity for a loud, clear performance With a high sensitivity of 105dB/mW, these headphones are highly efficient in converting electricity into acoustic signals. This means you hear clearer sound across the entire audio spectrum (compared to less sensitive headphones) when listening to music through the same source and at the same volume. Aluminum-coated LCP diaphragm for more precision An aluminum-coated, liquid crystal polymer diaphragm produces more consistent and precise sound across the entire frequency range compared with conventional LCP drivers. Sound energy lost during transmission to the headphone housing is more uniform for a true and authentic performance. Also enjoy a flatter frequency response, even when listening to the ultrahigh frequencies in High-Resolution Audio.
