MDR-1A Sony Premium Hi-Res Stereo Headphones

Take your digital music collection to another level with Sony's MDR-1A high-resolution stereo headphones. 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. 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. 

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. 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. 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. Precisely sculpted vents maximize the airflow in the headphone, allowing the LCP diaphragm to breathe more easily and deliver an instant response to powerful low-end bass lines.

The closed-back, enfolding design wraps around the ear, sealing in music and keeping out distractions. Acoustics are reflected back toward your ears, so you hear even the subtlest sounds. You also feel every beat, as the closed-back design maximizes the bass signatures in your music. With a balanced four-wire connection and silver-copper dual cord, audio channel separation is improved for better sound. Unlike conventional headphones, which share a ground wire, the cord includes left, right, and independent ground wires for both channels, so you hear less distortion and crosstalk. Soft leather earpads with pressure-relieving cushions, designed to rise and shape around your ears for a comfortable fit. Smooth materials and seamless stitching provide a harmonious mix of comfort and durability for long hours of listening. Take these headphones anywhere you go. A swivel folding design makes it easy to store them when not in use or while traveling. The earcups swivel flat to slip easily into a suitcase or bag.
