Redmi has officially revealed its latest flagship, the K90 Pro Max, setting a new benchmark in the premium smartphone segment. The device, scheduled to launch in China on October 23, 2025, introduces a first-of-its-kind collaboration with Bose, featuring a 2.1-channel audio system with a dedicated subwoofer-style rear speaker. This partnership underscores Redmi’s commitment to delivering superior audio experiences alongside cutting-edge smartphone technology.
Premium Design and Build
The K90 Pro Max showcases a sophisticated design with ultra-narrow bezels and a unibody metal “volcanic” camera housing. Its “Flowing Gold White” finish and denim-textured blue variant provide a modern aesthetic that combines elegance and durability. A standout design feature is the circular rear speaker located next to the camera module, branded “Sound by Bose,” marking the first collaboration between Redmi and the renowned audio company. Despite the inclusion of this innovative speaker, the device retains its IP68-rated water and dust resistance, ensuring both durability and functionality.
Immersive Audio System
The rear Bose speaker is engineered to function as a true subwoofer, offering deep, rich bass for an enhanced audio experience. Redmi Product Manager Sun Cun confirmed that the system delivers immersive sound without compromising the phone’s durability or design integrity. The 2.1-channel audio setup aims to elevate gaming, music, and video playback experiences, positioning the K90 Pro Max as a premium choice for audio-conscious users.
Powerful Specifications
Under the hood, the K90 Pro Max is powered by the Qualcomm Snapdragon 8 Elite Gen 5 processor, coupled with the D2 graphics chip, ensuring top-tier performance for gaming and multitasking. It sports a 6.9-inch display with “Qingshan Eye Protection 3.0,” 1-nit brightness support, and full DC dimming, designed to reduce eye strain during extended use. The device is backed by a 7,560 mAh battery supporting 100W wired fast charging, 50W wireless charging, and 22.5W reverse charging, offering both convenience and long-lasting performance.
Camera Capabilities
The smartphone features a 50MP primary camera with Optical Image Stabilization (OIS), a periscope telephoto lens capable of 5X optical and 10X lossless zoom, and an anticipated ultrawide lens for versatile photography. This camera setup ensures professional-level imaging and detailed shots across various conditions.
Launch and Global Availability
The Redmi K90 Pro Max will debut in China on October 23, 2025. There are expectations that it may be released internationally under the Poco F8 Ultra branding, allowing a broader audience to experience its innovative features.
With its premium design, advanced audio system, and flagship-level specifications, the Redmi K90 Pro Max is poised to redefine expectations for high-end smartphones in 2025, appealing to users seeking both performance and immersive multimedia experiences.
