Poco’s F9 Ultra pairs an ultra-bright display with a glowing Bose subwoofer

The Poco F9 Ultra smartphone features a unique Bose-branded subwoofer with integrated LED lighting and a high-performance 185Hz display. It targets mobile gamers with specialized audio profiles and high-brightness screen technology.
Why it matters
This device represents a niche trend in mobile hardware where manufacturers prioritize specialized audio and gaming-centric features over standard smartphone utility.
Xiaomi spinoff brand Poco has partnered with Bose for the second year in a row for its flagship F9 Pro and Ultra phones. The F9 phones double down on amped up audio, with a light-up subwoofer built into the Ultra, along with extremely bright displays, enormous batteries, and what should be Poco’s best cameras yet.
The F9 Ultra sees the return of the Bose-branded 2.1 sound system introduced on last year’s F8 Ultra. Poco has only slightly tweaked the hardware, upgrading each of the two main speakers while using the same subwoofer as before, but has changed the structure of the subwoofer mount to include a small LED ring around it. It’s only white, with no choice of color, but can be used for call and notification lights as well as rhythmic lighting during gaming or music, unlike the extremely limited HiLight feature in the new Pixel 11 phones.
