Many cameras have a built-in microphone, as part of their default features. If you have ever tried to record audio through your camera’s built-in microphone, however, you’ll have run into a few issues.
We’ll run through a couple of these issues, as well as present our solution to terrible in-camera audio: wireless microphones. This guide covers two Sennheiser systems for video, not every wireless microphone on the market.
Best Wireless Microphone
What Are Wireless Microphones?
Wireless microphones are a type of microphone that can transmit and receive sound wirelessly through radio waves, without the need for any cables.
Wireless microphones do not share one frequency or one range. The sets below use 1.9 GHz or 2.4 GHz, while other systems use UHF. Usable distance depends on the radio, the power, and what sits between the transmitter and the receiver.
The first wireless microphone was invented for original use in theater. It enabled people to speak from the stage without running cables through the theater.
Match your proposal to the rates you want to charge
Presentation matters: structure and wording that support premium positioning without feeling salesy.
Nowadays, you will see wireless microphones used everywhere: sports stadiums, concerts, even private meetings where mobility becomes important!
Most video cameras (especially DSLRs) weren’t built for good audio recording.
Manufacturers have spent their time and attention on creating a device that captures great video, but not necessarily great sound.
The sound quality may not be so high, volume may be weak, especially if your subject is not near the camera. And if you have unwanted background noise present, then all bets are off!
Unless you are in a quiet environment, you will definitely be able to hear road noise in the background, animal noises or unwanted conversation getting picked up. Unwanted non-diegetic sound!
Wireless microphones enable you to get a mic up close to the subject and record the audio that you actually intend on recording.

Audio Quality and Performance
The AVX Digital Wireless System employs cutting-edge digital transmission technology to deliver pristine audio quality.
It operates in the license-free 1.9 GHz band (1880–1930 MHz, depending on the country) and moves to a clear frequency when it detects interference.
The system offers automatic frequency management, which means it scans for the best available frequency and adjusts accordingly, minimizing dropouts and ensuring reliable wireless audio transmission.
The audio quality is exceptional, with a frequency response of 20Hz to 20kHz, capturing a wide range of audio frequencies with clarity.
Additionally, the system utilizes a high-quality microphone capsule that captures speech and dialogue with remarkable accuracy.
The system’s dynamic range and 19 ms latency further enhance its performance, making it suitable for various audio recording applications, including interviews, documentaries, and video production.
The video shows an AVX combo that adds a handheld transmitter. The set linked above is the ME 2 lavalier kit.

Sennheiser has packed the AVX Digital Wireless System with numerous features to streamline the audio recording process.
The system boasts one-touch pairing, allowing for quick and hassle-free setup.
It includes automatic sensitivity control, which adjusts audio levels in real-time to prevent distortion and ensure consistent audio quality.
The transmitter and receiver both use rechargeable lithium-ion packs: about 15 hours on the bodypack and over 4 hours on the receiver.
The receiver can switch on and off with the camera’s P48 phantom power. It does not power microphones that need phantom.
The AVX-ME2 set in the buy box includes the bodypack and an ME 2 lavalier. A handheld transmitter is a separate AVX set.
