[Xiaomi Poco X3 NFC Guides, News, & Discussion] ROMAZON:
the famous website for camera benchmark and testing DXOMARK recently made a full professional Audio review for Poco X3 NFC , they performed a variety of objective tests and undertake more than 20 hours of perceptual evaluation under controlled lab conditions.

so here I'll share some major summaries from their article , and will leave a link for their full article at the end for more in depth details.

Test summary

Considering the budget price of the Poco X3 NFC, its overall score of 63 is impressive, even if it means it’s an average audio performer. It scored higher than some much higher-priced smartphones, such as the Lenovo Legion Phone Pro, another gamer-centric model, which costs about twice as much.

In playback testing

, our engineers found the treble precise, with good high-end extensions. Spatialization came in for praise, with good wideness, localizability, and distance performances. Our engineers noted few artifacts. As for audio playback drawbacks, there is a strong lack of bass, and the excess of high-mids produces nasal-sounding and metallic resonances. Balance seems to be shifted to the right of the device in when in landscape mode. Minimum volume is too low, to the point that dynamic content is barely hearable or simply not hearable at all. The lack of bass heavily hinders precision and punch.

As a recording device

, the Poco X3 NFC produces average but consistent timbre performance in each use case. In the spatial attribute, it delivers good wideness. The recording loudness is also good in the memo app. And although there is some pumping and distortion on loud content, the device’s overall artifacts performance was fairly good. The signal-to-noise ratio is below average, with our engineers noting that background noise is very present and sounds unnatural because of the Poco X3 NFC’s midrange-focused and muffled rendering. The envelope is below average, and other than wideness, its spatial performances are not great. In the camera use cases, recording of loudness was below average; maximum sound level was average.

Conclusion

For a smartphone in this price range, the Poco X3 NFC turns in a solid all-round performance — nothing truly exceptional, but no big flaws either. It produces precise treble with good high-end extensions, and the spatial attribute is slightly above average, with good wideness, localizability, and distance performances. The device produces few artifacts. On the other hand, the lack of bass along with an excess of high-mids produces some unpleasant resonances. That lack of bass also dulls bass precision and punch. The minimum volume step is simply too low.

The device’s score as a recording device, while average, still lifts it above several more expensive models. Its timbre performance was average but consistent across the use cases. The Poco X3 NFC did a good job of recording loudness when using the memo app. It also produced fairly clean recordings, with few artifacts. On the negative side, the SNR was below average — background was overly present and unnatural-sounding because it was so midrange-focused. The dynamics performance was also slightly sub-par, with below-average envelope and spatial scores.
