The F8 Ultra is the first smartphone with a subwoofer, and this makes an audible difference that impressed us in our review. We subjected the sound system to additional measurements.

The Poco F8 Ultra clearly stands out from the competition with its Bose-optimised speakers, establishing itself as one of the best multimedia smartphones in the high-end segment. Unlike the Poco F8 Pro, which already impresses with Bose-tuned stereo sound, the Ultra model integrates an even more ambitious setup: two front speakers plus a dedicated subwoofer on the back provide a spacious, bass-heavy sound experience that takes films, games and music on the go to a new level.

Bose technology optimises frequency response, soundstage and dynamics specifically for the compact smartphone enclosure. In testing, the two symmetrical 1115F stereo speakers deliver a clear, balanced profile with strong bass thanks to the 1620 subwoofer – a difference that is immediately audible. High frequencies remain largely precise and mid-range frequencies natural, even at high volumes. At maximum volume, there is only minimal distortion, which is exceptional for a device of this size. The subwoofer not only enhances action scenes in films, but also provides immersive gaming sound and rich beats. It hardly matters whether the device is held in your hands or placed on a table; the sound quality remains consistent.

Compared to competitors such as the Samsung Galaxy S25 Ultra or iPhone 17 Pro Max, the Poco F8 Ultra sets new standards: Bose provides a wider sound stage and deeper bass without the need for headphones. Dolby Atmos and Hi-Res Audio support round off the setting.

Despite its strengths, at extreme volume levels, a slightly more powerful amplifier could make the highs even tighter. Overall, Bose makes the Poco F8 Ultra a real audio highlight: perfect for users who see their smartphone as a portable concert hall.
