Sony NW-WM1ZM3/WM1AM3/ZX900 Three Flagship Walkman Digital Music Players Listed for China at 10,999–29,999 Yuan
IT Home, November 13 — Sony's Signature series flagships NW-WM1ZM3 and NW-WM1AM3, along with the slightly lower-positioned NW-ZX900, three Walkman digital music players, have now been listed for the China market.


Among them, the NW-WM1ZM3 is priced at 29,999 yuan, the flagship NW-WM1AM3 at 16,999 yuan, and the sub-flagship NW-ZX900 at 10,999 yuan, with a deposit of 500 yuan for all three products. Pre-orders will close at 12:00 noon on November 15, with final payment accepted from November 15 to 16, and shipping expected on November 16.

The NW-WM1ZM3 flagship features a 99.99%-purity gold-plated oxygen-free copper (OFC) body with an overall gold-plated finish, and even the body screws undergo a low-resistance gold-plating process. Sony says this provides a more stable ground connection, resulting in more powerful bass, a wider soundstage, and smoothly extended highs.


The NW-WM1AM3 and NW-ZX900 adopt an aluminum alloy main body paired with a gold-plated OFC rear body, balancing body rigidity, light weight, and sound quality. The WM1 series also upgrades from a single large-capacity solid polymer capacitor to dual capacitors, combined with hand-soldered OFC wiring, to provide cleaner and more stable power delivery.



In terms of software and audio processing, all three models are equipped with S-Master HX digital amplification technology and a DSD remastering engine. The latter can resample PCM audio into an 11.2MHz DSD ultra-high-frequency audio stream for a presentation closer to analog sources; with this upgrade, the feature can be enabled for both locally downloaded and Wi-Fi streaming playback. S-Master HX also adds a "look-ahead noise shaper," which is said to process transient signals faster and more clearly.
Battery life and screens have also improved. The NW-WM1ZM3 and NW-WM1AM3 feature 5.5-inch screens, with up to about 35 hours of MP3 playback and up to about 31 hours of streaming playback; the NW-ZX900 uses a 5-inch screen, with up to about 40 hours of MP3 playback and up to about 35 hours of streaming playback.
