VoxRadius
Engineered To Protect Your Voice, All Day Long
Why You Can Speak, Not Shout
The headset mic sits close to your mouth, so it picks up your normal speaking voice instead of a shout, then projects it clearly across the room.
Light Enough To Forget It's There
Small and light with an adjustable strap for waist or neck wear, so it stays comfortable through a full day of classes, tours, or coaching sessions.
Reinforced Where Cheap Ones Fail
The clips and charging port are reinforced for the on-and-off routine of daily use, built to keep working through a full school year or tour season.
UHF Signal Cuts Out Feedback
It runs on a UHF frequency instead of standard Bluetooth, keeping the signal steady and largely free of the squeal cheaper mics produce.
What our 17,000+ Customers say
Based On Real and Honest Experiences
VoxRadius totally changed my classroom. It's more accessible for every one of my kids now, and it's so much easier on my voice by the end of the day. I'm not hoarse by Friday anymore.
I teach spin five days a week and VoxRadius is so small I forget I'm wearing it, but it makes my voice really loud over the music. My cues carry to the back row without me yelling over the speakers.
After two cheap amplifiers that squealed and died within a year, I wasn't expecting much from VoxRadius. No feedback, no straining to be heard, and my tour group in the back can finally hear every word.
Frequently Asked Questions
How long does the battery last on a full charge?
How long does the battery last on a full charge?
One full charge runs about 4 to 6 hours of continuous use, and a full recharge takes around 4 hours. That covers back-to-back classes or tours comfortably; for an extra-long day, top it up on a lunch break.
Will it be loud enough for a full classroom or noisy tour group?
Will it be loud enough for a full classroom or noisy tour group?
Yes. VoxRadius is rated to project clearly across spaces up to 1000 square meters, more coverage than a typical classroom or tour group needs. You speak at a normal volume and the back row still hears you.
Is the headset mic wireless? Will it interfere with school WiFi?
Is the headset mic wireless? Will it interfere with school WiFi?
The mic connects on its own UHF wireless frequency, completely separate from WiFi and Bluetooth, so a school network full of devices won't cause lag, dropouts, or interference with your voice signal.
Is it comfortable to wear all day?
Is it comfortable to wear all day?
Yes. It's lightweight with an adjustable strap you can wear at your waist or around your neck, so it stays comfortable through a full day of classes, tours, or coaching without pulling at your ears.
Will this hold up, or will it break like my last one did?
Will this hold up, or will it break like my last one did?
VoxRadius is built with reinforced clips and a protected charging port, the two spots where cheaper amplifiers usually fail first. It's designed for the daily clip-on, clip-off routine of a full school year or tour season.
How do I avoid whistling or feedback?
How do I avoid whistling or feedback?
Wear the speaker at your waist facing away from the headset mic, start around 50% volume, and raise it gradually until it sounds right. Once positioned correctly, feedback is rarely an issue.
Can I play music or connect it to my phone?
Can I play music or connect it to my phone?
Yes. Plug in a USB drive or TF card to play and loop tracks from the display screen, or connect your phone to stream your own playlist between cues or announcements.
Will it work outdoors in the wind, or with a mask on?
Will it work outdoors in the wind, or with a mask on?
The headset mic sits right at your mouth, so it still picks up your voice clearly with a mask on, and the body-worn speaker projects over wind and traffic better than your voice alone.
