(IEM Review) Westone Pro X30: Stage monitor with emphasis on midrange. Not for everyday music appreciation. Good for listening to explanatory videos or practicing your instrument.

Sound quality description

In this review, I use the standard eartips size L and drive it with the FiiO M15.


The Westone Pro X30 is a stage monitor that emphasizes the sound of the midrange. Even on a stage where the audience is buzzing and the lights are dazzling, the artist can still hear the songs and the entire show. As a result, vocals and rhythms are clearly captured, but the sound is inorganic and utilitarian, lacking dynamism and subtlety, making it less suitable for music appreciation.


Please see here for detailed reviews on sound quality.


Sound quality general comment
  • Original Sound Fidelity: B-
  • Recommendation: C+
  • Personal preference: D


The Westone Pro X30 is a very well built performer's monitor. It is optimized to prioritize listening to rhythm, vocals, foreman instructions, and narration, which are essential for stage performances. It is made to be ideal for very limited applications, not suitable for use in music appreciation or DTM, and is too expensive.


They are designed for people who practice their own instruments or songs, want precise rhythm expression for sound games, or need to use earphones for a long time for study, and can be listened to for a long time without getting tired and maintaining a comfortable fit.


If you are looking for earphones that are suitable for DTM or music listening, you don't have to pile up a high amount of money because for $30 you can get the far more optimal and sound quality Tripowin Lea.

General comment

The Westone Pro X30 is a very good stage monitor, it lets you hear rhythms accurately, it sounds great even after long hours of listening, and it has a stable fit. However, it is not at all suitable for ordinary people to listen to music. This is because they are not designed for that purpose. The narration is easy to hear and the rhythm is easy to understand, so they are suitable for singing, practicing sound games, and watching lecture videos.
