Features
- Enjoy optimal audio performance with Sony-unique DSEE HX technology. DSEE-HX revitalizes high-frequency audio response while also up-scaling existing audio signals (MP3, AAC, ATRAC, and WMA) to high-resolution levels.
- An extruded aluminum enclosure fits nicely in-hand and also protects the delicate circuitry inside from outside interference and impacts, while integrated, front and rear alloy endcaps protect the terminals from hard knocks. Recessed controls also reduce the chance of accidental access during playback.
- The internal rechargeable battery provides approximately 5 hours of balanced audio playback when connected digitally via USB, or up to 28 hours of playback when connected using the analog, 1/8” stereo input.
- Digital cables for Walkman and Xperia, micro-USB cable, stereo mini cable, silicone belt, and Protection sheet.
