Sony MDR-1ADAC Hi-Res Headphones with USB DAC Amp

Sony announced $400 hi-res headphones, which integrate a digital-to-analog converter/amplifier, model MDR-1ADAC. The built-in USB DAC amp takes the digital output of your PC or mobile device and converts the signal to an analog output for amplification. The MDR-1ADAC can play both PCM (at up to 192 kHz /24-bit) and DSD (at up to 5.6 MHz) music files directly, without the need of an external decoder. Additionally, its built-in S-Master HX digital amplifier reduces noise and distortion across all frequencies, and reproduces each track in outstanding detail. The MDR-1ADAC headphones support PCM 192 kHz/24 bit, and DSD 2.8MHz/5.6MHz — New 40mm aluminum coated liquid Crystal Polymer HD drivers also deliver frequency response up to 100kHz.

The new MDR-1ADAC headphones also come with multiple-inputs and the cables that are necessary to connect to a smartphone, portable audio player or PC. In order to accelerate the Hi-Res experience, Sony has created several different cables for direct connection – including the specially developed thin and flexible USB connecting cable, the Digital connecting cables specifically for Walkman and Xperia devices, an exclusive iOS Lightning connector cable as well as a conventional audio connecting cable. Plus its built-in rechargeable battery provides up to 7.5 hours of continuous playback. When the battery runs low, you can continue to enjoy your music in a conventional manner.

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 earcup movement. In the end, you can expect an immersive listening experience.
