The vivo X300 Ultra will bring a host of improvements compared to its predecessor, and while we’ve mostly focused on the photographic side of them, there’s another side to it: audio.
Vivo’s Han Boxiao took to Weibo to tease some substantial improvements to the audio capture and audio reproduction of the upcoming global flagship.
The first has to do with enhancements to how the phone uses its four available microphones. They’ll combine spatial recording with noise reduction and AI smarts to isolate voices and enhance the sound recording.
Below is a screenshot Boxiao shared from the X300 Ultra’s new camera app. The phone will be able to capture audio directionally, tune recording to the phone’s front or back, have noise reduction (from 0 to 100%), and even gain adjustment (from -100 to 100), which is something of a pro feature.

The other improvement is more hardware-based and less AI. The X300 Ultra is getting a bigger and smarter top speaker. It will reportedly be nearly 3 times larger with a cavity of 0.8cc. That’s around a 167% increase in physical size, per vivo. Flagship phones typically have around 0.3cc to 0.5cc speaker cavities. That’s because the camera module, which typically sits in the top part of the phone, reduces the space.
Vivo has also boosted the amplifier by 20%. The result, per Boxiao, is a nearly 4dB improvement in the lower (bass) frequencies around 300Hz, and a wider high frequency by 3kHz. That means the top response could extend from 17kHz to 20kHz, which, while impressive on paper, would likely be lost on most users.
Vivo has reportedly reworked the entire upper right side of the phone to serve as a speaker enclosure and moved the speaker’s cavity cover “to the bracket”. Vivo says it has patented this innovative design.
It sounds like a mix of realistic hardware-based claims and a touch of marketing speak. We’ll know when we test the speakers in-house.
