Nokia X5 (Nokia 5.1 Plus) Review

Audio Test

The audio test has been performed by using the TASCAM US-2x2 audio interface and the RightMark Audio Analyzer software as usual. All audio enhancement features are disabled. The test results unveil an average audio quality. The Frequency Response on our review unit is rated as excellent. The Noise Level, Dynamic range, THD, IMD + Noise, IMD at 10 kHz and the Stereo Crosstalk are rated as very good. The THD + Noise gets an average mark. The overall result is Very good. There's one, bottom-firing speaker placed to the left of the USB Type-C port. According to our subjective opinion, it is not super loud but is loud enough to lead a conversation in a moderately noisy environment. However, you might actually enjoy listening to music from the speaker as the sound is balanced and generally better than the one from speakers on other affordable mid-rangers.
