Lavalier
Lavalier microphones, or lav mics, are a valuable addition to any filmmaker’s kit but are not the most critical tool. They serve a specific purpose, excelling in situations where portability, high-quality sound, and concealment are essential. Lav mics are ideal for shots where a shotgun mic cannot be hidden or would be too far from the subject. They also shine in scenarios involving multiple actors speaking, moving across a scene, or being spread out, thanks to their ability to connect individually to compact lav recorders on each subject.

Best Budget
The Rode SmartLav is a solid budget-friendly option for filmmaking. It provides decent audio quality, suitable for entry-level projects, though it may introduce a noticeable hiss in quiet environments, typical of lower-budget options. This can usually be cleaned up in post-production, resulting in a usable and close-recorded track. Its affordability makes it a practical choice, allowing filmmakers to equip multiple actors simultaneously rather than compromising on coverage or alternating recordings. Ideal for testing the waters or pairing with a shotgun mic for versatility.
Best Value
The Rode Lavalier GO is one of the most popular lavalier microphones. While it offers slightly less performance than the Lavalier II, the sound difference is barely noticeable. Built in the traditional lavalier style, it remains a solid choice, offering great value for its price.

Best - Arguably
The Rode Lavalier II is the latest version from Rode, featuring a new design with the mic positioned flat instead of pointing upwards, aimed at capturing audio as it leaves the speaker. This design provides a larger mic surface for better reach compared to the previous model. Though it costs more, it includes additional features like a furry windscreen. It's a great lavalier microphone, but unless you're considering a single mic, the Wireless Pro bundle might offer more cost efficiency.
