Do mid-range [wireless mic kits](https://www.podcastvideos.com/articles/cable-therapy-when-going-wireless-becomes-a-technical-nightmare/) hold up against high-end pro gear? In a side-by-side test, the [Saramonic K9](https://store.saramonic.com/products/k9?srsltid=AfmBOoqKinztNUJ8l%5FrnrCzUocZ1oX5mCZ1Cs4FXCimjBdKuek2OCEL%5F&ref=podcastvideos.com), [Deity THEOS](https://deitymic.com/products/theos-digital-wireless/?ref=podcastvideos.com), and [Sound Devices Astral](https://www.sounddevices.com/astral/?ref=podcastvideos.com) were run through the same setup to find out. The focus: high-frequency clarity, artifacts, and real-world usability.

### Key Findings

- **Sound Devices Astral** had the cleanest high end—no filtering, no digital shimmer.
- **Deity THEOS** showed strong high-frequency filtering and minor digital artifacts.
- **Saramonic K9** had mild filtering, with less aggressive artifacts than THEOS.
- A **16 kHz low-pass filter** cleans up both budget mics nicely for most users.

### Real-World Use

All three were recorded simultaneously into a [Sound Devices 888](https://www.sounddevices.com/product/888/?ref=podcastvideos.com) using matched lav mics. No processing beyond loudness matching. What you hear is what each mic delivers natively.

Even if you detect a difference on studio monitors, most people watching content on YouTube or learning platforms likely won’t. For creators, educators, and indie filmmakers, the K9 and THEOS are more than serviceable—with a simple EQ tweak.

### Bottom Line

- **On a budget?** Grab the Saramonic K9 or Deity THEOS, and add a low-pass filter if needed.
- **Want pro-tier audio?** The Astral kit is expensive, but it delivers pristine results with zero fuss.

Audio purists might nitpick—but if it sounds good to your ears, it’s good enough.
