Dedicated music players have become specialist devices, and Sony is leaning further into that distinction. The NW-WM1ZM3 Signature Series Walkman puts an elaborate audio circuit inside a gold-plated, precision-machined oxygen-free copper chassis, prioritizing wired listening over smartphone convenience.

The flagship succeeds the WM1ZM2 in Sony’s premium portable-audio lineup. Its copper construction is intended to reduce electrical interference, while carefully selected internal components, upgraded power circuitry, and oxygen-free copper wiring support the company’s approach to cleaner signal delivery. The player uses Sony’s S-Master HX digital amplifier architecture alongside DSEE Ultimate processing and a DSD Remastering Engine.

The hardware is substantial for a portable device: the body measures approximately 3.39 by 6.20 by 0.91 inches and weighs 1.48 pounds. A 5.5-inch Full HD touchscreen runs Android 16, allowing streaming applications alongside locally stored music. Built-in storage is 256GB, with a microSD slot for expansion. A conventional 3.5mm headphone jack sits beside a 4.4mm balanced output; Bluetooth 5.4 and Wi-Fi add wireless connectivity.

Sony quotes up to 33 hours of playback for 24-bit/96kHz FLAC files through its music app, with runtime depending on format and connection. For listeners already invested in high-resolution portable audio, the WM1ZM3 represents an unusually material-intensive alternative to a phone and external DAC. Sony’s regional product pages list the model, but a confirmed U.S. retail price and release date have not been established.
