Xiaomi’s Redmi brand is poised to launch its K90 Pro Max flagship smartphone featuring integrated Bose audio technology and a distinctive “Tech Denim” material design, aiming to set it apart in the competitive global market.
The device will incorporate true Bose-branded speakers within its rear camera module, a significant audio upgrade. This 2.1 channel system includes two main speakers and a dedicated subwoofer, designed to provide an immersive sound experience for gaming, video consumption, and music playback.
These speakers are engineered to be water-resistant, ensuring they do not compromise the phone’s overall durability. The K90 Pro Max also features a software-driven sonic dust removal system, which uses sound waves and vibrations to keep speaker ports clean and maintain high audio quality.
Another notable design element is a “Tech Denim” version of the phone. This material is a modernized denim fabric, offering a tactile experience similar to real denim. It is also designed to enhance protection against dust and scratches, while providing better heat dissipation compared to standard black or white finishes.
Redmi’s Product Manager, Sun Cun, shared details on Weibo, confirming the K90 Pro Max’s IP68 rating. This certification guarantees complete protection against dust and allows the device to be immersed in up to 1.5 meters (approximately 5 feet) of freshwater for 30 minutes.
The K90 Pro Max is expected to debut in China on October 23, 2025. Unofficial reports, including those from prominent tipster Digital Chat Station, have detailed further specifications.
The smartphone will reportedly be powered by Qualcomm’s latest flagship chipset, the Snapdragon 8 Elite Gen 5, with processing speeds reaching up to 4.60 GHz. It is also said to feature a flat 6.59-inch 2K resolution display and an ultrasonic fingerprint sensor embedded beneath the screen.
For photography, the device is rumored to include a 50-megapixel main camera utilizing a 1/1.3-inch image sensor, complete with Optical Image Stabilization (OIS). A periscope zoom camera will complement the main sensor, adding advanced telephoto capabilities.
