This feature allows the microphone to effectively block out unwanted background noise and transmit clear and crisp audio. One example of a wireless microphone renowned for its outstanding background noise rejection is the Shure SM58. This microphone utilizes a cardioid polar pattern that focuses the pickup pattern on the main sound source, reducing the pickup of surrounding noise. Another excellent option is the Sennheiser EW 135-P G4. This microphone features a supercardioid pickup pattern, which provides even stronger background noise cancellation than a cardioid pattern. Additionally, the AKG D5 offers excellent background noise rejection thanks to its patented Laminate Varimotion diaphragm technology that filters out unwanted noise.
Microphone type (handheld, lavalier, headset)
There are three main types to choose from: handheld, lavalier, and headset.
Handheld microphones are the most common type and are often used in live performances and presentations. They are easy to hold and control, making them a popular choice for singers and speakers. One example of a high-quality handheld microphone is the Shure BLX24/PG58 Wireless Handheld Microphone, which features a cardioid pickup pattern and a frequency response range of 50 Hz to 15 kHz.
Lavalier microphones, also known as lapel or clip-on microphones, are small and discreet. They are often used by television presenters, public speakers, and performers who need their hands free. A noteworthy option is the Sennheiser EW 112P G4-G Portable Lavalier Wireless System, which includes an omnidirectional lavalier microphone and offers a frequency response range of 40 Hz to 18 kHz.
Headset microphones are similar to lavalier microphones but incorporate a small microphone capsule that is worn on the performer's head. They are commonly used in fitness classes, theatrical productions, and sports events. One compelling choice is the Audio-Technica System 10 ATW-1101/H92TH-TH Headset Wireless System, which features an adjustable headset for a comfortable fit and a frequency response range of 20 Hz to 20 kHz.
Each microphone type serves different purposes, so it's important to choose based on your specific needs and application.
Microphone sensitivity
Microphone sensitivity refers to how well the microphone is able to pick up and amplify sound. Higher sensitivity microphones are ideal for environments with low sound levels, as they can capture even the faintest of sounds. On the other hand, lower sensitivity microphones are suitable for environments with louder sound levels as they can handle high sound pressure without distorting the audio.
There are different types of wireless microphones available in the market that cater to various sensitivity requirements. For instance, the Shure SM58 is a popular choice among musicians and entertainers with its high sensitivity (dBV/PA: -54.5) that captures detailed vocals and instruments even in noisy environments. Alternatively, for larger venues and professional audio production, the Sennheiser e945 offers a slightly lower sensitivity (dBV/PA: -51) for improved rejection of feedback and optimal performance. Additionally, budget-friendly options like the Audio-Technica AT2020 Wireless have excellent sensitivity (dBV/PA: -37) for personal use and casual recording sessions. The sensitivity of the microphone is crucial in ensuring clear and accurate sound reproduction, making it an essential factor to consider when making your wireless microphone purchase.
Microphone pickup pattern
The pickup pattern determines the direction and scope from which the microphone can capture sound. There are several common pickup patterns to choose from:
Cardioid: This pickup pattern captures sound from the front of the microphone while reducing noise from the sides and rear. The Audio-Technica AT2020 Cardioid Condenser Studio Microphone is a popular choice for podcasting and studio recordings.
Omnidirectional: An omnidirectional microphone captures sound from all directions equally. This is ideal for capturing ambient sound or in situations where multiple sound sources need to be recorded simultaneously. The Shure MV88+ Video Kit offers an omnidirectional microphone option for video recording.
Bidirectional: As the name suggests, a bidirectional microphone captures sound equally from the front and back while minimizing side noise. This pattern is commonly used for interviews or recording two people facing each other. The Rode NT-USB Mini USB Microphone features a bidirectional mode for added versatility.
It's important to choose the pickup pattern that best suits your specific recording needs to ensure clear and accurate sound reproduction. Additionally, be sure to check the frequency response range and signal-to-noise ratio of the wireless microphone, as these factors also contribute to its overall performance.
