Soft leather earpads provide a comfortable fit during long listening sessions. 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/192kHz, rather than 16-bit/44.1kHz), High-Resolution Audio allows you to get closer to the original studio recording.Sony MDR-Z7 High-Resolution Audio Headphone with 70mm HD driver units power through your music, keeping every note precise, no matter how high you turn up the volume. Because of their massive size, these drivers create a plane wave effect in the earcups that prevents reflection delays and minimizes sound loss. So you can hear all the emotion and energy of the original recording with punchy bass and crystal clear high notes. The wideband frequency range - spanning 3Hz to 100kHz - is designed for today's broad variety of music styles. The 3Hz low end of the frequency range offers more than enough latitude for even the deepest sub-bass notes. At the 100kHz high end, you'll be able to enjoy vocal melodies, subtle audio harmonics and tonality.&nbsp;Sony MDR-Z7 High-Resolution Audio Headphone with a sensitivity of 105dB/mW, these headphones are highly efficient in converting electricity into acoustic signals. That means you'll hear a clearer sound across the entire audio spectrum when listening to music through the same source and at the same volume level. An aluminum-coated, liquid crystal polymer diaphragm gives a consistent sound across the entire frequency range. Sound energy lost during transmission to the headphone housing is more uniform, to ensure a true and authentic performance. You'll also enjoy a flatter frequency response, even when listening to the ultra high frequencies of High-Resolution Audio.The closed-back, enfolding design wraps around the ear, helping to seal in music and keep distractions out. Acoustics are reflected back towards your ears, so you'll hear even the subtlest of sounds. You'll also feel every beat, as the closed-back design helps to maximize the bass signatures in your music.
