Enjoy up to 45 hours of portable, high-resolution audio with the Sony NW-A45B Walkman Digital Music Player, offered here in a grayish black finish. This Walkman supports playback of PCM, AAC, WMA, and MP3 audio files, among others. It features 16GB of internal flash memory and supports microSD cards. The NW-A45 also boasts a 3.1" TFT color LCD touchscreen with an 800 x 480 resolution. Its built-in rechargeable battery provides up to 45 hours of continuous audio playback on a full 4-hour charge.
This Walkman utilizes several audiophile-friendly technologies, including DSD over PCM Playback and DSEE HX upscaling. Sony's wireless codec, LDAC, delivers a higher bit rate than standard Bluetooth, so you can enjoy an enhanced listening experience with a compatible pair of wireless headphones. You can also pair the Walkman with other compatible devices over conventional Bluetooth with NFC.
The NW-A45’s proprietary operating system works with Mac and Windows computers, and utilizes a simple drag-and-drop process for quickly moving songs from your computer library to the Walkman. Also, you can use the NW-45B as a USB DAC, circumventing your computer’s sound card and achieving better sound in the process through the unit’s S-Master HX amplifier.
