Product Information

MDR1A Hi-Res Headphones With 40mm Drivers


MDR1A Features:

Pure sound-every note!

  • Drawing inspiration from a legacy of personal audio reproduction, Sony engineers have developed the perfect balance of Premium style and hi-resolution audio performance. Introducing the MDR-1A Stereo Headphone featuring thoughtful design, lush long-term comfort, and ultra-responsive Hi-Res audio response for a sound experience bar-none.

Prepare for exceptional sound

  • Lightweight and responsive, aluminum-coated Liquid Crystal Polymer driver units possess the necessary rigidity and internal loss to deliver linear, wideband frequency response ranging from sub-harmonic lows (3 Hz) to ultra-sonic highs (up to 100 kHz) for balanced and natural sound reproduction.


  • Silver-coated oxygen-free copper (OFC) cable ensures minimal signal transmission degradation for pure audio response at the driver. A unique 4-wire architecture further enhances the audio experience, with a separate ground and signal connection to each driver for enhanced separation, expanded sound and tight bass.

Comfortable fit, powerful sound

  • Pressure-relieving urethane cushions wrap entirely around your ears for a comfortable acoustic seal and powerful bass response, while precise component machining, with the added placement of silicon rings around every moving axis, realizes smooth and silent ear cup movement. In the end, you can expect an immersive listening experience.

Upgrade your cans

  • Elevate an already outstanding listening experience to new levels via high-grade cables. High-performance wire paired with precision hardware facilitates the high-resolution, noise-free delivery of your favorite good-vibrations to your ears. Three models are available to suit: on-the-go (MUC-B12SM1), at-home (MUC-B30UM1), or balanced audio listening styles (MUC-B20BL1). Consult your retailer for further information.

Smartphone compatible

  • Specifically designed for Android smartphones, a configurable in-line remote with microphone delivers personalized music and call functionality. Using the free SmartKey APP (available at Google Play and the App Store) you can customize the in-line remote, control settings via your smartphone.

Supplied Accessories

  • Two, supplied cables accommodate listening flexibility. A conventional connecting audio cable (1.2 m), in addition to an in-line microphone and remote cable for smartphone (1.2 m). A convenient carrying pouch is also supplied to keep your headphones and accessories secure.
