The Aeromic AM11LS is Fitness Audio's headset microphone for instructors who teach in high-sweat rooms every day: HIIT, cycling, dance and group fitness. Hand-built in Australia by Fitness Audio, maker of instructor microphones since 1994, it is rated for up to 7 classes a day, 7 days a week when two mics are rotated (see Rotation below), and covered by a 2-year sweat warranty.
The low-sensitivity LS capsule sits behind double mesh and an acoustically transparent Carbon Collar, which stops sweat clogging the capsule and gives you more volume before feedback. The capsule is fully potted and sealed. A one-piece hand-moldable PhatFrame, an all-steel cable and a connector with four layers of sweat defense are why Aeromics stay in service for years.

Rotation: how to get the full rating
The 7-classes-a-day rating assumes you alternate two Aeromics, using each one every other class, or take the windscreen off and give a mic an hour to dry between classes. Sweat needs time to dry out of the capsule and connector. A single mic used back-to-back will not last as long as the rating suggests.
All class ratings are for non-consecutive classes. Hot classes (hot yoga, hot Pilates): up to 3 hot classes a day, non-consecutive.
Weight 1.2 oz. All-steel cable, 45.3 in. Full specifications are in the table below.

Aeromic · The daily-driver headset
Built for seven classes a day.
Hand-built in Australia for instructors who sweat through HIIT, cycle and dance every day. Rated for up to 7 classes a day with two mics in rotation, and covered by a 2-year sweat warranty.
How it lasts
Seven a day. Seven days a week.
The Aeromic is rated for up to 7 classes a day, 7 days a week, when you alternate two mics so one dries while you teach on the other.
Between classes, pull the windscreen off and give the resting mic about an hour to air out. That keeps the capsule and connector dry, and it's what the 2-year sweat warranty assumes.
Example day
One instructor, two Aeromics
- 6:00 AMCycleMic A
- 7:15 AMHIITMic B
- 12:00 PMPumpMic A
- 5:30 PMDanceMic B
- 6:45 PMBootcampMic A
The mic you're not wearing dries with its windscreen off.
For the instructor
1.2 oz on a frame you shape once. The capsule sits beside your mouth, so there's no breath blast and no big foam ball in front of your face.
Order it with the connector that matches your transmitter (TA4F, TA3F, 3.5 mm locking or MTU8) and it plugs into Shure, Sennheiser, AKG, Samson and Fitness Audio packs. Not sure which? Use the Connector Finder. Or skip the beltpack: an MTU8 mini transmitter mounts straight on the frame.
Treat the windscreen as a consumable. Swap it every few weeks and the sound stays clean.
For the gym
Buy two per instructor on a heavy schedule and the rotation takes care of itself. Black with the yellow boom, so it's easy to spot on the rack.
2-year sweat warranty, repairs done in California, and support by email at info@fitaud.com.
Hot yoga or cycle studio? The Cyclemic has the same capsule on a J-curve boom that drains sweat away. Lighter schedule? The EMic is the value pick at up to 20 classes a week, with the same rule: two in rotation, windscreen off to dry.

FAQ
Frequently asked questions by current and future customers
Why does a fitness instructor need a specialty headset mic instead of a regular one?
Standard headset mics are designed for theatre and corporate use — they fail within months in a fitness environment because sweat corrodes the cable, swells the capsule foam, and rusts exposed metal. The Aeromic was engineered from the ground up for fitness: all-steel cable instead of copper, one-piece polymeric frame with no exposed metal, Carbon Collar around the capsule, and four layers of sweat defense at the connector. It's the difference between a tool built for the job and a tool adapted to it.
What is the 2-Year Sweat Warranty and what does it cover?
The Aeromic carries a conditional 2-year warranty against sweat damage. It covers use of up to 7 classes per day, 7 days a week, with two mics in rotation or an hour of drying time between classes. Most headset mic manufacturers explicitly exclude sweat from their warranty; the Aeromic is warrantied against the thing most likely to kill it. Keep your purchase receipt as proof of date.
Will the Aeromic work with my existing wireless system?
Almost certainly yes. The Aeromic uses our MultiMic connector system that fits every major wireless brand: Fitness Audio, Shure, Sennheiser, Audio-Technica, AKG, Samson, MiPro, Telex, Sony, Nady, JTS, Chiayo, TOA, and others. Tell us your bodypack make and model when you order and we'll confirm the right connector — most commonly TA4F (4-pin mini-XLR) for Shure/Fitness Audio/MiPro or TA3F (3-pin mini-XLR) for AKG/Samson.
Can I use one Aeromic across multiple gyms with different wireless brands?
Yes — that's exactly what MultiMic was designed for. If you teach at Gym A on Shure and Gym B on Fitness Audio, a single Aeromic plugs into both. This is especially valuable for traveling presenters, master trainers, and freelance instructors working across multiple facilities.
What is the Low Sensitivity (LS) capsule and why does it matter?
Counter-intuitively, lower sensitivity gives you more usable volume in a room. The LS capsule delivers more gain before feedback starts, behaves better with digital signal processors, and is more compatible with bodypacks from other brands. In practice: you can push the mic louder over the music without that piercing feedback squeal.
Will the Aeromic stay on during high-impact choreography?
Yes. Instructors teach BodyPump, plyometrics, kickboxing, dance, and high-impact aerobics in Aeromics without issue. Once you bend the one-piece PhatFrame to fit your head, the behind-the-head design locks in place through jumping, burpees, and head movement. No bouncing, no shifting, no readjusting mid-class.
Do I need a foam ball windscreen?
No. Because the capsule sits beside the mouth instead of in front of it, breath blasts and plosives are physically avoided rather than masked. A small windsock is included for added vocal warmth and an extra sweat barrier, but you'll notice professional Aeromic users don't have the giant foam ball that's common on other brands.
How do I clean and care for it?
Wipe the boom and headband with a dry or barely-damp cloth after each class. Don't submerge it, don't spray cleaner on the capsule, and never store it wet inside a bag. Let it air-dry in a ventilated space between sessions. The windsock can be rinsed gently and air-dried separately. Proper care is what gets you 3–5+ years of life from a single mic.
What's the difference between the Aeromic and the Cyclemic?
Same internal capsule, same PhatFrame, same all-steel cable, same Carbon Collar, same 2-year warranty. The Aeromic comes in black-and-yellow with a straight boom for general group fitness — instructors who move around the room and aerate the mic naturally. The Cyclemic comes in black-and-orange with a J-curve boom specifically to drain sweat for forward-leaning cycle and hot yoga instructors. Cycle or hot yoga = Cyclemic. Everything else = Aeromic.
Can I use the Aeromic for hot yoga if I rotate two of them?
It will work, but the Cyclemic is the better choice for any heated environment. The J-curve boom specifically addresses the sweat-drainage problem of fixed-position, high-heat teaching. If you teach a mix of heated and non-heated classes, many instructors own one of each.
Can multiple instructors share one Aeromic?
We strongly recommend each instructor have their own headset — the windsock and earpieces sit against the face and absorb sweat. The wireless bodypack can be shared between instructors, but the headset itself should be personal, like a toothbrush. For the same reason, headset mics cannot be returned once worn.
Does the Aeromic include a wireless transmitter?
The Aeromic on its own is the headset only — you plug it into your existing wireless bodypack. If you don't have a wireless system yet, we offer Aeromic bundled with the Fitness Audio U-Series UHF system, the DX6 Digital Wireless system, the Mini-TX armband (no separate bodypack), and major third-party brands. Contact us and we'll spec a complete package for your facility.
Will the Aeromic sound exceptional through any sound system?
It sounds great through almost any system, but it sounds exceptional through a Fitness Audio Aeromix mixer (1+1 SR, 2+2 SR, or 3+5 LS). The Aeromix mixers are tuned by the same engineering team that builds the Aeromic — clean highs, punchy bass, no low-volume hiss, and the smoothest gain-before-feedback behavior. The two products are designed to work together.
How do I order the right Aeromic for my situation?
Get in touch and tell us: (1) your wireless bodypack brand and model, (2) whether you teach heated or non-heated classes, and (3) your weekly class load. We'll confirm the connector, recommend one mic or two for rotation, and quote a complete system if you need one.
