A wireless microphone gets the mic closer to the person speaking without running a cable back to the camera. That means cleaner audio for interviews, presentations, events and content where your subject needs room to move.
Built-in camera microphones can pick up more surrounding sound because they sit further away. A wireless setup lets you place the microphone closer to the voice.
Choose a Wireless Microphone for How You Record
Different microphone styles suit different jobs. Think about who you are recording and how much they need to move.
Clip-On Lavalier Systems
Lavalier mics clip onto clothing and leave the speaker's hands free. They suit interviews, presentations, social content and videos with one or two speakers.
Handheld Wireless Microphones
Handheld systems work well for interviews, presenting and live performance. They are also easy to pass between speakers when several people need to talk.
Headset Microphones
Headsets keep the microphone close to the mouth while leaving both hands free. They are useful for presenters, instructors and performers who move around while speaking.
Wireless Shotgun Systems
Shotgun microphones can be paired with compatible wireless or plug-on transmitters to remove long audio cables. This suits run-and-gun video and shoots where the microphone needs to sit away from the camera.
Understand 2.4GHz and UHF Wireless
Many compact wireless systems use the 2.4GHz band. They are easy to set up and suit content creation and smaller productions, although nearby Wi-Fi and other wireless devices can create congestion.
UHF systems give you more control over frequency selection and can suit setups running several wireless channels. UHF operates within regulated spectrum, so check that the system and frequency band meet current ACMA requirements for use in Australia.
Connect Your Microphone to Your Gear
Your connection depends on what you record with. Cameras commonly use 3.5mm or XLR inputs, while phones may connect through USB-C or Lightning. Compatible computers can connect through USB.
Some combinations need an adapter or audio interfaces. You can also compare camera microphones and audio recorders if wireless is not the right fit for every recording job.
Check Range, Battery Life and Backup Recording
Wireless range figures are usually measured in favourable conditions. Walls, crowds and competing wireless signals can reduce how far a system works reliably, so do not choose on the advertised maximum alone.
Check battery life against the length of your usual shoots. Charging cases are handy for compact systems, while replaceable batteries can work better when you need to record for longer.
Some transmitters can also record audio internally as a backup. A safety track records a second version at a lower level, which can help if the main recording suddenly gets too loud.

FAQs
Do I need a licence to use a wireless microphone in Australia?
You do not normally need to apply or pay for an individual licence when using a compliant wireless microphone under the applicable ACMA class licence. You still need to use permitted frequencies and follow the licence conditions. Check current ACMA requirements before buying or using a UHF system, particularly one purchased overseas.
Can two wireless microphone systems be used in the same room?
Yes, compatible systems can often run together. Each needs a clear channel or suitable frequency arrangement to avoid interference. Check how many simultaneous channels the system supports if you plan to use several microphones.
Will a wireless microphone work with a smartphone?
Many wireless microphones work with compatible smartphones through USB-C or Lightning. Some combinations need an adapter or interface. Check the connection and phone compatibility before choosing a system.
What causes dropouts and static during recording?
Distance, walls, crowds and competing wireless signals can all affect the connection. Frequency congestion can also cause problems. Keeping a clear path between the transmitter and receiver where possible can improve reliability.
How far can a wireless microphone realistically transmit?
It depends on the system and where you are recording. Advertised ranges are often measured in open spaces with a clear line of sight, so everyday range may be shorter. Walls, people and interference can all reduce the usable distance.
