If you run a spin class, a bootcamp, a dance studio, a training room or walking tours, you need to be heard over music and movement — with both hands free. A headset microphone on a wireless bodypack is the answer. Here's how to build a reliable setup.
The kit
| Item | Why | Price* |
|---|---|---|
| AIR-B2 dual-channel system | Receiver + two handhelds for guests, announcements or a co-instructor | $247.99 |
| AIR-BX-B1 bodypack | Belt-pack transmitter with headset and lapel mics | $69.99 |
| AIR-BX charging dock (optional) | Keeps the bodypack and a handheld charged at the front desk | $69.99 |
*AUD inc GST at the time of writing.
The bodypack pairs to channel 1 of the AIR-B2 by IR sync; channel 2 stays available for a handheld or a second bodypack for a co-instructor.
Why a headset, not a lapel?
- The mic stays at the same distance from your mouth as you move, so your level stays constant.
- It sits close to the mouth, so it needs less gain — much less prone to feedback in a room full of speakers.
- It picks up less music and room noise than a chest-clipped lapel.
The AIR-BX-B1 includes a lapel too — handy for seated sessions like yoga, meditation or a boardroom talk.
Why the receiver matters in a gym
- True diversity — two antennas per channel handle bodies moving between you and the receiver.
- USB-C powered receiver — runs from a power bank for outdoor bootcamps and park sessions.
- Up to 100 m line of sight — more than enough for a studio or an oval.
- Low latency (<2.9 ms) — your voice stays in time with your movements.
Battery life for a busy timetable
The bodypack runs about 10 hours on its removable 18650 cell. For studios running classes from 5 am to 8 pm, keep a charged spare cell and swap at lunchtime.
Sweat, movement and wear
- Clip the bodypack to the back of a waistband or use a running belt or armband pouch.
- Route the cable under clothing so it doesn't catch.
- Wipe the headset down after classes; store it dry.
- Position the capsule at the corner of the mouth, not in front, to reduce breath noise.
Connecting to your studio sound
Most studios have a mixer or amplifier with a mic input. Use the receiver's XLR output for the headset channel, or the 6.35 mm mixed output into a single input. Keep the music a little lower than you think — a clear voice beats a loud track.
FAQ
Can two instructors use headsets at the same time?
Yes — use two AIR-BX-B1 bodypacks, one on each channel of the AIR-B2.
Will it work outdoors?
Yes. Power the receiver from a power bank and keep it in sight of the class.
