Sony NW-A45 overview

  • 1Description

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.

Hi-Resolution Amplifier
Optimized for High-Resolution Audio, the S-Master HX amplifier reduces distortion and noise, allowing you to enjoy all the subtleties in your music.
The NW-A45B supports DSD audio formats by way of high-quality PCM conversion.
DSEE Upscaling
The Digital Sound Enhancement Engine HX (DSEE HX) upscales compressed digital music files such as MP3, AAC, ATRAC, and WMA, bringing them closer to the quality of high-resolution audio.
Precision-Engineered Build
The circuit board of the NW-A40 Series has been engineered for efficiency. The layout from the battery to the audio block minimizes the power loop, making the power supply stable. This results in a clear sound with solid low end. Other precision-engineered components include lead-free solder on the circuit board and the S-Master HX chip (CXD-3778GF), resulting in an efficient electronic connection.
Ambient Sound Mode with Compatible Headphones
Listening to music but still want to hear the outside world? When you're using compatible IER-NW500N headphones, select Ambient Sound Mode and the NW-A45B will let in external sounds to keep you aware of your surroundings.
LDAC Transmission
LDAC uses a conventional Bluetooth connection, but transfers at a maximum data transfer rate up to 990 kbps–approximately three times that of other audio profiles. The result is a wireless listening experience capable of streaming PCM files with high sample rates.
Use your NW-A45B as a USB DAC (digital-analog converter) by pairing it with a Mac or Windows PC. When connected and activated using the supplied USB cable, the unit replaces your computer's regular sound processing with its own hardware.
Touchscreen Controls
With the large, full-color touch screen, you can change tracks, create playlists, and more.
Bluetooth with NFC
Near Field Communication (NFC) and Bluetooth technology make connecting to your music fast and easy. Just touch your NFC-enabled device to the NW-A45B for a seamless connection, then start streaming.
MQA Support
The NW-A45B is fully compatible with MQA, furthering its functionality when it comes to lossless music.
Expandable Memory
Want to store more music on your Walkman? Pop in an SD card (available separately) for additional memory.
Handy Buttons for Quick Control
The play/pause, music selection, and volume buttons on the side panel are shaped and positioned for easy operation.

    Sony NW-A45 reviews

    NWA45B Walkman Digital Music Player (Greyish Black) is rated 4.7 out of 5 by 3.
    Rated 5 out of 5 by from Didn't know what I was missing until now. Wow. Just wow. I'm stunned with the sound and build quality. I've been using an ipod version (older than the classic) with the Wolfson DAC. It finally died and instead of fixing it I decided to move on.�I absolutely hated using my smart phone for music. So I did tons of research on DAC players and felt this unit fell in a reasonable price range.� After purchasing this, I picked up a 256 micro sd card and downloaded the sony media software for managing the audio content. The results are amazing. 100 times easier to work with than itunes. Using this player is like rediscovering my music all over again. Has Bluetooth and FM radio. Battery life is stellar as well.� I would highly recommend over apple audio products.

    Rated 4 out of 5 by from Good quality but very high priced The player has great sound and features. Do not go by Sony's web site for the spec's on this product. The pictures are a bit deceiving showing color matching headphones. Even the paperwork included with the product says the wired ones come with it. Calling Sony they explain that they only supply them in Korea and The UK.� Understand without them the FM Radio function will not work as they are needed for the antenna. I would have given 5 stars had they been included.

    Rated 5 out of 5 by from Great Dedicated Music Player Great sound and feature. Seamless integration with MusicBee. Easy connection with Bluetooth speakers/cars. Only complaint is that the FM receiver can't tune in my station at work but trying a few headphone options to help the antenna. Great product.
