Sony NW-WM1Z Review

How does the audio quality compare?

The Sony NW-WM1Z delivers a remarkably rich and detailed sound experience, supporting high-resolution audio formats including DSD and PCM up to 384 kHz/32-bit. Its proprietary hardware design and operating system focus solely on audio playback, stripping away unnecessary smartphone features that could compromise sound quality.

Compared to competitors like the Astell&Kern AK380 and FiiO X7, the WM1Z stands out for its warm tonal balance and expansive soundstage, making it particularly suited for classical and jazz genres.

Is the design as premium as claimed?

Constructed with a solid gold-plated copper chassis, the NW-WM1Z not only provides aesthetic appeal but also contributes to its robust build quality. It weighs 455 grams, giving it a premium feel while being somewhat bulky for a portable device.

User feedback highlights that while the weight is a minor inconvenience for on-the-go use, it significantly adds to the device's premium perception and durability.

How user-friendly is the interface?

The user interface is intuitive, albeit slightly dated, featuring a simple layout that caters to a straightforward audio experience. It includes physical buttons for navigation, which some users appreciate over touch-screen controls prevalent in modern devices.

While the simplicity enhances accessibility, some users have noted the limited functionality in terms of app integration as a drawback compared to smartphone-like competitors.

Does it last for long listening sessions?

With a battery life touted to last up to 30 hours of continuous playback for standard audio formats, the NW-WM1Z performs admirably in this area. It supports fast charging, allowing users to quickly get back to enjoying their music.

However, users have reported that playing high-resolution audio formats can reduce the runtime significantly, with some experiences suggesting a fall to around 10-15 hours, particularly when using Wi-Fi features.

Is it worth the investment?

Considering its premium materials and superior audio quality, the price point is justified for dedicated audiophiles. However, casual listeners may find it excessive for their needs, especially given alternative options that provide substantial audio quality at lower price points.

Simultaneously, some reviews indicate that the NW-WM1Z’s performance still holds up against newer models, ensuring its relevance in the high-end market even years after release.
