What are the main performance differences between Sony ux series recording pens and px series recording pens? Such as ux533 and px333

For example, these two models are quite different in performance. The PX series is an entry-level model, which only meets the general recording needs, and the noise reduction effect and recording distance are limited. The UX series further optimizes the noise reduction and even adds FM frequency modulation. The two-way microphone makes the recording effect more stereoscopic.
