Build Quality: The NW-ZX300 features supreme build quality
with a 3.1"
TFT WVGA color display (800 x 480 pixels) with white LED backlighting. It has a
capacitive touch screen made of matte glass to allow smooth fingertip control
with fewer fingerprints. The device is
constructed with a rigid aluminum milled frame to keep the circuit boards secure,
preventing noise and distortion. The circuits and components are attached to the
circuit board with a Sony-developed high-quality, lead-free solder for a purer signal path. The
S-Master HX digital amplifier is optimized for high-resolution audio playback,
delivering smooth, natural sound over a wide 20Hz-40kHz frequency range.
DSEE-HX: Sony has included their DSEE-HX "up-scaling"
technology in the NW-ZX300. DSEE-HX uses an algorithm to analyze the music, and
automatically replace the "lost" information. DSEE-HX (Digital Sound Enhancement
Engine) gives your highly-compressed music files new life so they
sound almost as good as true Hi-Res Audio quality.
Memory: The NW-ZX300 has a 64 GB internal memory, which has
the capacity for the following number of recordable songs:
- MP3 (128 kbps): 15,000 songs
- AAC (256 kbps): 7,600 songs
- 44.1 kHz/16-bit: 1,300 songs
- 96 kHz/24-bit: 420 songs
- 192 kHz/24-bit: 210 songs
- 2.8224 MHz/1-bit: 340 songs
- 5.6448 MHz/1-bit: 170 songs
- 11.2896 MHz/1-bit: 80 songs
Note: The unit's
memory card slot will also accept microSD cards for even more memory capacity.
Bluetooth/NFC: With built-in Bluetooth 4.2, you can stream your music files wirelessly
devices up to 30 feet away. Devices that have the NFC (Near-Field Communication)
function, can be automatically turned on, and paired with the Walkman, by simply
touching the back of the Walkman to the device on the NFC logo.
Sound Quality Settings: You can adjust the sound quality
with the following selectable functions: Equalizer/Tone Control, DSEE HX, DC
Phase Linearizer, and Dynamic Normalizer. You can save up to 3 sound settings
for later recall.
Rechargeable Battery: The Walkman has a built-in Lithium-Ion
rechargeable battery for exceptional stamina.
