Rode Wireless GO II with Lavalier GO
The Rode Wireless GO II paired with their Lavalier GO has become my go-to recommendation for speakers who need absolute reliability without complexity. After I reviewed this system at a three-day corporate training event, I was genuinely impressed by how it handled everything I threw at it walking between rooms, presenting outdoors during lunch sessions, and even dealing with the RF interference from hundreds of smartphones in a crowded ballroom. The dual-channel capability means you can mic two speakers simultaneously, which proved invaluable when I moderated a panel discussion last spring.
What sets this system apart is the onboard recording feature that saved me during a keynote when the venue’s sound system decided to cut out mid-presentation. The transmitters were capturing clean audio as backup the entire time, and I didn’t lose a single word. The Lavalier GO itself features an omnidirectional condenser capsule that picks up natural voice reproduction without that harsh, overemphasized presence peak you hear in cheaper lavs. In my experience, the 4mm diameter cable strikes the perfect balance between durability and discreteness thick enough to avoid that fragile feeling but thin enough to hide under most clothing without creating rustling sounds.
Pros:
- Dual-channel recording with onboard backup storage prevents audio loss
- Exceptional wireless range and reliability in challenging RF environments
- Compact transmitters easily clip to clothing without weighing down fabrics
- Universal USB-C charging eliminates proprietary battery concerns
- Clean, natural voice reproduction without excessive sibilance
Cons:
- Omnidirectional pattern picks up more ambient noise in loud environments
- Battery life of about seven hours requires mid-day charging for full-day events
- No true diversity reception system like professional UHF wireless sets
- Included lavalier cable could be slightly longer for more placement flexibility
Shure MVL Omnidirectional Condenser Microphone
Sometimes simplicity wins, and the Shure MVL proves that wired lavalier microphones still have their place in public speaking scenarios. I keep this mic in my presentation kit specifically for podcast interviews and situations where I’m recording directly to my smartphone or laptop without needing wireless transmission. When I tested it during a webinar series last fall, the audio quality genuinely surprised me this $50 microphone delivered clarity that rivaled systems costing ten times more, provided you don’t need to move beyond the cable length.
The MVL connects via TRRS, making it compatible with smartphones, tablets, and computers without requiring additional adapters or interfaces. During a month-long speaking tour where I was doing both live presentations and capturing behind-the-scenes content, this mic became my reliable companion for quick social media videos and impromptu interviews. The foam windscreen effectively reduces plosives and breath noise, though I learned to position it slightly off-center from my mouth for the most natural sound about two inches below and to the side of my chin works perfectly.
Pros:
- Exceptional value delivering professional sound quality under $60
- No batteries or charging requirements completely plug-and-play operation
- Universal TRRS connectivity works with smartphones, tablets, and computers

- TRRS connection incompatible with XLR-based professional audio systems
Sennheiser XSW-D Portable Lavalier Set
The included ME 2-II lavalier microphone represents decades of Sennheiser’s engineering expertise in miniature form. When I tested this during outdoor speaking engagements, the cardioid-ish pickup pattern (they call it “speech-optimized omnidirectional”) rejected wind noise and crowd conversations significantly better than true omnidirectional capsules. The sound signature emphasizes vocal intelligibility with a gentle presence lift around 5-8 kHz that helps voices cut through without sounding harsh or sibilant. I’ve recorded hours of presentations with this system, and the consistent audio quality across different rooms and venues demonstrates remarkable engineering.
What impressed me most during extended testing was the battery life the transmitter runs for five hours on a single charge, while the receiver keeps going for five hours as well. The compact receiver plugs directly into XLR inputs on mixing boards or camera systems, eliminating bulky belt pack receivers. I particularly appreciate the mute switch on the transmitter, which I’ve used countless times during conference breaks to avoid broadcasting casual conversations. The system also includes a 3.5mm jack receiver option, giving you flexibility to connect to cameras or recording devices without XLR inputs, something that proved essential when I needed to capture content for musicians exploring their craft through various media.
Pros:
- Digital 2.4 GHz transmission eliminates traditional frequency coordination hassles
- Automatic channel switching prevents dropouts in crowded RF environments
- Compact form factor with multiple receiver options for different applications
- Cardioid-influenced pattern improves isolation in noisy speaking venues
- Sennheiser sound quality delivers broadcast-ready audio reproduction
Cons:
- Five-hour battery life insufficient for full-day conferences without recharging

- Digital transmission introduces slight latency unsuitable for music performances
- Higher price point than comparable analog wireless systems
Audio-Technica AT831b Cardioid Condenser Lavalier
Sometimes you need a lavalier that connects to professional audio systems, and the Audio-Technica AT831b fills that specific niche beautifully. When I reviewed this mic for a corporate training series where we ran it through a professional mixer and PA system, the transformerless output delivered remarkably low self-noise and excellent dynamic range. The cardioid pickup pattern became particularly valuable in a challenging hotel ballroom with terrible acoustics it rejected the room reverb and ambient HVAC noise that omnidirectional mics would have captured mercilessly.
The 55-inch cable terminating in a locking 3-pin mini XLR connector (with included XLRF adapter) gives you professional connectivity that interfaces seamlessly with bodypack transmitters or hardwired setups. In my experience, this represents the sweet spot between broadcast-grade lavaliers costing thousands and consumer-oriented models that compromise on build quality. The metal housing inspires confidence compared to plastic-bodied alternatives, and after a year of regular use, mine shows zero signs of wear beyond some minor cosmetic scratches on the clip.
During sound checks for a speaker series I presented last year, our audio engineer specifically commented on how well this mic handled gain before feedback compared to the venue’s house lavs. The frequency response extends smoothly from 40 Hz to 18 kHz, capturing the full richness of the human voice without the thin, telephone-like quality of cheaper microphones. I’ve found it particularly effective for speakers with deeper voices, as it reproduces low-frequency chest resonance naturally without boominess. The included foam windscreen and clothing clip cover the essentials, though I eventually invested in a furry windscreen for outdoor presentations where even light breezes created unwanted rumble.
Pros:
- True cardioid pattern provides excellent rejection of ambient noise and feedback
- Professional mini XLR connection integrates with bodypack transmitters seamlessly
- Extended frequency response captures full, natural voice reproduction
- Durable metal construction withstands professional touring and daily use
- Transformerless design delivers low self-noise for clean audio in quiet passages
Cons:
- Requires separate wireless bodypack transmitter or hardwired connection to mixer
- Phantom power requirement needs 11-52V from professional audio systems
- Cardioid pattern demands more precise positioning than omnidirectional alternatives
- Higher cost than consumer wireless systems with built-in transmitters
Sony ECM-LV1 Compact Stereo Lavalier Microphone
The Sony ECM-LV1 occupies an interesting position in my microphone collection it’s the one I recommend to speakers who primarily create video content alongside their live presentations. When I tested this during a series of lecture recordings for an online course, the stereo capsule configuration captured a sense of space and dimension that mono lavaliers simply cannot reproduce. The dual omnidirectional elements positioned on the same clip create a surprisingly wide stereo image that makes recorded presentations feel more engaging and immersive when played back.
What makes this microphone particularly valuable for public speakers transitioning into content creation is its versatility across different devices. The cable splits into two 3.5mm plugs one for microphone input and one for headphone monitoring which works perfectly with smartphones, DSLR cameras, and portable recorders. I’ve used mine extensively for capturing presentation footage, and the ability to monitor audio in real-time through the second plug has saved me from multiple recording failures when connections worked loose or cables got bumped. The nine-foot cable provides plenty of length to position your recording device on a podium or nearby table while maintaining freedom of movement.
Pros:
- Stereo recording creates more engaging spatial dimension for video content
- Split cable design enables real-time monitoring during critical recordings
- Nine-foot cable provides generous reach for various recording setups
- Dual windscreen options cover both indoor and outdoor recording scenarios

Frequently Asked Questions
What’s the difference between omnidirectional and cardioid lavalier microphones?
Omnidirectional lavaliers pick up sound equally from all directions, which creates natural voice reproduction and forgives imperfect placement on clothing. However, they also capture more ambient room noise, audience conversations, and HVAC sounds. Cardioid lavaliers focus their pickup pattern forward, rejecting sound from the sides and rear, which gives you better isolation in noisy environments and reduces feedback potential when working with PA systems. In my testing, omnidirectional works best for controlled recording environments and smaller venues, while cardioid becomes essential in challenging acoustic spaces or when you need maximum gain before feedback.
How should I position a lavalier microphone for optimal sound quality?
After testing dozens of placements across hundreds of presentations, I’ve found the sweet spot is typically six to eight inches below your chin, positioned near the center of your chest on whichever side feels more comfortable. This placement captures clear voice reproduction while minimizing breath noise and plosives that occur when mics sit too close to your mouth. I always clip the microphone to stable clothing like shirt collars or jacket lapels rather than loose fabrics that create rustling sounds with movement. The cable should drape naturally with a small service loop near the clip to prevent tugging from transmitting handling noise to the capsule.
Do wireless lavalier systems work reliably in conference venues with lots of RF interference?
Modern digital wireless systems using 2.4 GHz transmission have dramatically improved reliability in crowded RF environments compared to older analog UHF systems. When I’ve used digital wireless at major conferences with hundreds of attendees, the automatic frequency hopping prevented the dropouts and interference that plagued earlier technologies. That said, I always arrive early for sound checks and keep a wired backup microphone in my kit technology occasionally fails, and having a contingency plan ensures your presentation continues smoothly regardless of technical difficulties.
How much should I expect to spend on a quality lavalier microphone for professional speaking?
Professional-quality lavalier systems range from around $50 for wired options like the Shure MVL up to $300-400 for complete wireless setups like the Rode Wireless GO II. In my experience, the $200-300 range delivers the best value for serious speakers, providing broadcast-quality audio, reliable wireless performance, and durability that survives regular travel and use. Budget options under $100 can work for occasional speakers or those just starting out, but investing in quality audio equipment pays dividends in professional credibility and presentation impact over time.
