Should I use a lavalier, handheld, or headset microphone?

Each type has specific strengths. Lavalier (lapel) microphones clip to the presenter's clothing and are hands-free, making them the standard for corporate keynotes, TED-style talks, and any presentation where the speaker needs to use their hands or move freely. The tradeoff is that audio quality depends heavily on placement, and clothing rustle or movement can introduce noise.

Handheld microphones offer the best overall sound quality and reliability because the capsule stays at a fixed distance from the mouth. They're ideal for Q&A sessions, award presentations, guest speakers, and any situation where the mic passes between multiple people.

Headset (earset) microphones wrap around the ear and position the capsule near the corner of the mouth. They offer the best clarity and level consistency because the mic moves with the speaker's head. They're the standard for theatre, high-energy presenters, live demos, fitness instructors, and any scenario where the speaker is physically active. The visual profile is more noticeable than a lavalier.
