Sony Walkman WM1 Series Portable Audio Player NW-WM1ZM2 [256GB]

◆The pursuit of sound quality leads to unprecedented excitement. Signature Series
The Signature Series is the culmination of unconventional sound creation based on all of the high-quality sound technologies that Sony has cultivated to date.
What we sought was the reproduction of minute sounds, from the moment the performance begins, when the singing begins, to when the final sound fades away into complete silence.
With a power of expression that allows you to feel the atmosphere, temperature, and humidity of the venue, we aimed to deliver a luxurious musical experience and the full emotional impact of music that comes with the pursuit of sound quality.

◆High-performance full digital amplifier "S-Master HX" compatible with high-resolution playback
Supports DSD native playback (up to 11.2MHz) and linear PCM playback (up to 384kHz/32bit).
In addition, the maximum practical output is 60mW + 60mW (16Ω) when connected unbalanced, and 250mW + 250mW (16Ω) when connected balanced.

◆ "DSEE Ultimate" gets even closer to high-resolution audio sources with AI technology
Supports lossless audio sources, expanding 44.1kHz/16bit audio sources up to 192kHz/32bit equivalent
Using AI (artificial intelligence) technology that has learned vast amounts of music data, the music's scenes are analyzed in real time and optimally upscaled to high-resolution sound quality (※).
The bits are expanded and the sampling frequency is increased to a maximum of 192kHz/32bit. AI technology is used to automatically identify songs and improve the reproduction of subtle sounds.
In addition, thanks to the evolution of the AI ​​algorithm, the upscaling performance of CD-quality audio sources (44.1kHz and 48kHz/16bit) has also been improved.
*When "DSEE Ultimate" is ON for both wired and wireless connections. (Extended up to 192kHz/32bit) When connected wirelessly (Bluetooth) with LDAC codec, playback is possible at up to 96kHz/24bit. [NW-WM1ZM2/NW-WM1AM2]

◆High-quality 10-band equalizer (31Hz-16000Hz)
High-quality signal processing allows fine-tuning of sound quality. Multiple adjusted settings can be saved.

◆ Supports balanced output that completely separates left and right sounds
Balanced output completely separates left and right sounds and outputs sound signals without going through the ground. It reduces crosstalk (interference between left and right signals) that adversely affects the stereo feeling, and reproduces delicate sound with low noise and distortion.

◆Uses a φ4.4mm (JEITA unified standard) balanced connection for high connection stability
It uses a φ4.4mm headphone jack (5-pole) that allows for a balanced connection with a single headphone plug and provides excellent connection stability.

◆Uses the high-performance headphone jack "Pentaconn" made by Nippon Dicks
One terminal, two contacts reduces contact resistance. The structure with two contacts per terminal makes the resistance values ​​of each channel closer than with a normal φ3.5mm connector, and also lowers the contact resistance, allowing for the full expression of sound resolution, breadth, and depth.
* "Pentaconn" is a registered trademark of Nippon Dix Co., Ltd.
◆ Carefully selected parts with attention to detail in pursuit of even higher sound quality
It delivers natural, smooth, high-quality sound that makes you feel as if you are listening to a live performance right in front of you. It is equipped with a variety of carefully selected high-quality parts, including a gold-plated machined oxygen-free copper housing with a purity of approximately 99.99%.
By using a new high-quality solder with gold added to the hand-soldered and reflow soldered areas, the ability to reproduce fine sounds is improved, resulting in improved spread and positioning.
By combining each part in an exquisite balance, including large parts that are used in desktop amplifiers, we have achieved stronger power supply and lower impedance.

◆ Gold-plated oxygen-free copper machined housing
It takes about 1.5 times longer to process aluminum to cut oxygen-free copper with a purity of about 99.99%. We chose oxygen-free copper because it is difficult to cut, and we prioritized sound quality. The increased purity reduces the resistance value.
It combines low impedance with high rigidity, and reproduces clear, powerful low frequencies and extended, crisp high frequencies.
*Compared to our previous model NW-WM1Z

◆Installing oxygen-free copper cutting blocks for even lower impedance
Impedance is significantly reduced by installing a gold-plated oxygen-free copper machined block (approximately 99.96% purity) between the housing and the board.
It improves the ground stability of the digital block equipped with a CPU, built-in memory, etc., achieving clear sound quality that rises from silence.

◆ Compatible with Google Play Store and streaming services
You can install streaming services such as Amazon Music, Apple Music, LINE MUSIC, Spotify, and YouTube Music according to your preference.
We offer a huge variety of music across all genres, so you can enjoy not only your favorite songs but also discover new music.

◆360 Reality Audio playback possible - A new experience with sound pouring in from all directions -
A new music experience that makes full use of Sony's spatial audio technology, creating a immersive sound field that makes you feel as if you are in the room where the artist is performing live.
You can experience 360 ​​Reality Audio by subscribing to a compatible music streaming service such as Deezer or nugs.net and playing compatible content. The Walkman NW-A100 series, NW-ZX500 series, and WM1 series are equipped with the full digital amplifier "S-Master HX" (※), and are designed for high quality sound that is unique to music-only devices, allowing you to experience 360 ​​Reality Audio with great sound.
When combined with Sony's 360 Reality Audio certified headphones, your Walkman, which supports personal optimization (※2), can deliver a more three-dimensional sound experience.
*1 S-Master HX is only available with a wired connection.
*2 To personalize your Walkman, you will need "Headphones Connect" and the "360 Spatial Sound Personalizer" app on your smartphone.
*360 Reality Audio only supports playback of audio content. 360 Reality Audio does not support playback of video content.

◆Side buttons that are easy to operate even when the item is in a bag
Hardware buttons for basic operations (play/stop, skip forward/backward, volume control, etc.) are located on the side of the device. They are large and easy to press, so you can operate the device without looking at the screen, even while it's in your bag, on the train, etc.

◆USB Type-C(R) terminal
The highly versatile USB Type-C(R) connector has been adopted, which has faster data transfer speeds and charging times, improving convenience.
*When connecting headphones with a USB Type-C(R) connector, you may not be able to adjust the volume on the volume control screen depending on the headphones.
Headphones that do not have volume controls may produce a loud volume, so please refrain from using headphones with a USB Type-C(R) connector.
