I forgot phones could still surprise me until I tried one with a subwoofer

The POCO F9 Ultra pairs flagship hardware with a dedicated Bose-tuned subwoofer, and one noisy party convinced me smartphone speakers can still be genuinely interesting.

I forgot phones could still surprise me until I tried one with a subwoofer

I recently experienced a reminder of the surprising capabilities of smartphones when I tested the POCO F9 Ultra. This device surprised me with its powerful 2.1-channel audio system, featuring symmetrical 1115D stereo speakers and an independent 1620 subwoofer. This combination, tuned by Bose, creates an immersive sound experience that cuts through noise and highlights vocals and detail in music.

The phone's subwoofer delivers distinct bass notes, making the overall sound fuller without muddying the midrange frequencies. Despite its small size, the F9 Ultra manages to recreate the experience of a larger Bluetooth speaker, making everyday tasks more vibrant. The subwoofer's prominent circular grille adds to the device's unique design, and its dynamic lighting enhances functionality during calls, music playback, and supported games.

While the F9 Ultra doesn't rival the capabilities of flagship smartphones, it delivers a balanced audio performance and a refined design, making it a standout choice among modern devices.
