OnePlus 5 remains the affordable price with the best processor and larger RAM, but not the audio sub-system. OnePlus was not the best ones in audio performance in this price range, but also not the worst ones.

OnePlus 5 is equipped with Qualcomm Snapdragon 835 processor, the CODEC of it may be the WCD9341 that Qualcomm recommended, but some vendors are using the former WCD9335. We do not know which one OnePlus choose.

By convention, we use professional sound card to record sounds, combined with common analysis, to provide quantitative results. The output level of OnePlus 5 is -6dB, similar to that of iPhones.

We met problem on OnePlus 5, the harmonic distortion is similar to that of HTC U11. We found out that this problem comes from Netease Cloud Music, not the engineers. Some Netease Cloud Music versions may lead to a SRC problem, such as 4.01, and the built-in music players of OnePlus and HTC are Netease Cloud Music with SRC problem. It is easy to solve this problem, update to the latest version. We will update our HTC U11 audio review recently.

The latest Netease Cloud Music passed tests successfully, few harmonics, ideal indicators, no SRC problem, but no Hi-Res support.

It is a little surprising when we hear it, as OnePlus enhanced power, so the sound is not as tiny as before, and creates the stereo imaging, not that hard. The power enhance helps users have more earphones to choose. We recommend you to buy a vivo, an OnePlus relative, XE800. This earphone can represent sound dedicate with strength and thickness on sound. What's more, OnePlus 5 + XE800 are far better than those $20 entry MP3 players.

OnePlus 5's audio performance is one of the best among smartphones without separated DAC. Recently we may gather those best smartphones without separated DAC to see which one is the best.
