Poco has unveiled its F9 Pro and F9 Ultra smartphones, marking the second consecutive year of collaboration with audio specialist Bose. The devices double down on audio performance, with the F9 Ultra featuring a Bose 2.1 sound system that returns from last year's F8 Ultra.
The Ultra model houses a dedicated subwoofer with a small LED ring around its mount, while the two main speakers have been upgraded from the previous generation. The F9 Pro also features Bose speakers, though without the subwoofer.
Beyond audio, Poco describes the F9 phones as having extremely bright displays, enormous batteries, and what it calls its best cameras yet. The company has not yet released full specifications, pricing, or availability details.
The partnership with Bose is a key differentiator in the competitive smartphone market, where audio quality is often an afterthought. Last year's F8 Ultra was the first Poco phone to include a Bose subwoofer, and the company appears to be refining the concept with the new models.
