Top 5 Smartphone Microphones for Quality Audio

Buying Guide for Smartphone Microphones

Each year, new smartphones flood the market, boasting enhanced camera capabilities and larger displays. However, one area that continues to lag behind is the built-in microphone. The sound quality of these integrated mics often leaves much to be desired, making external microphones a necessity for anyone looking to capture high-quality audio. Whether you’re a podcaster, vlogger, or simply want clearer sound for everyday recordings, investing in a good microphone is essential.

Smartphone microphones are generally compact and connect via the headphone jack or charging port. While many wired options ensure consistent sound quality, Bluetooth alternatives offer freedom of movement. With a plethora of choices available, this guide will help you navigate the best options suited to your needs.

Key Considerations

Microphone Style

Smartphone microphones come in a variety of styles, each designed for specific use cases:

Clip-on (Lavalier) Microphones: Easy to attach to clothing, these mics capture audio from all directions. They allow for freedom of movement, ideal for interviews or casual vlogs.

Shotgun Microphones: These directional mics are perfect for reducing background noise, as they need to be pointed directly at the sound source. They are excellent for vlogging and interviews.

Handheld Microphones: These versatile mics are great for interviews and general use, capturing sound from all angles.

Stereo Microphones: Featuring multiple capsules, these mics can adjust to create different sound profiles and often include gain-control knobs for real-time adjustments.

Connection Types

Most smartphone microphones connect via the 3.5mm headphone jack, making them easy to use without any additional hardware. However, as many smartphones move away from traditional jacks, USB-C and lightning connector models are becoming increasingly common. Adapters are available to expand compatibility with various devices.

Size and Portability

One of the main advantages of smartphone microphones is their portability. Clip-on mics are compact and easily transportable, while larger handheld and shotgun models might require a carrying case.

Features to Look For

Software Compatibility

While many smartphone microphones are plug-and-play, some come with companion apps. These apps allow you to adjust settings like gain and noise levels on the fly, which can be particularly useful for achieving optimal sound quality.

Wireless Connectivity

With the rise of wireless technology, many brands now offer cordless microphones. Although generally pricier, they provide greater freedom of movement, making them ideal for dynamic content creation.

When shopping for microphones, you may come across the term “signal-to-noise ratio” (SNR). This ratio compares the level of desired sound to background noise, with higher SNR values indicating clearer audio.

Accessories

Many smartphone microphones come with useful accessories, such as pop filters and carrying cases. The more included tools, the better, as they can enhance your recording experience and save you time in the long run.

Price Ranges for Smartphone Microphones

Budget Options

You can find entry-level smartphone microphones for as little as £10 to £20. These typically include basic clip-on and lavalier mics that deliver decent audio quality for casual use.

Mid-range Choices

In the £40 to £60 range, expect higher-quality microphones with directional capabilities and additional accessories like pop filters and carrying cases.

Premium Models

If you’re willing to invest £80 to £100 and beyond, you’ll find microphones that approach studio quality, often featuring multiple output options including XLR and USB, suitable for both smartphones and traditional studio setups.

Tips for Recording

• Reduce Background Noise: When recording, ensure you’re in a quiet space. Turn off fans and minimise electrical interference to enhance audio quality.
• Maintain Microphone Distance: Keep the microphone at a consistent distance from the speaker to ensure even audio levels.
• Use a Pop Filter: If recording voice, consider using a foam windscreen or pop filter to eliminate popping sounds from plosive consonants.
• Check Sample Rates: Ensure your recording app is set to at least 44.1 kHz for optimal audio quality.
• Use a Carrying Case: Protect your microphone and accessories with a sturdy case to prevent damage.

Frequently Asked Questions

Q. What do terms like “polar pattern,” “omnidirectional,” and “cardioid” mean?

A. Microphones differ in how they capture sound, determined by their polar pattern. Some are sensitive to sound from all directions, while others focus on specific areas. Common patterns include:

• Omnidirectional: Captures sound equally from all directions.
• Unidirectional: Best for sound directly in front of the microphone, commonly found in shotgun mics.
• Bidirectional: Sensitive to sound from the front and back.
• Cardioid: Captures sound well from the front but less from the sides and back.
• Multi-pattern: Offers various polar patterns in one device for flexibility.

Q. What is the difference between condenser and dynamic microphones?

A. Condenser microphones are sensitive and suited for capturing delicate sounds, making them popular in studios. However, they may pick up unwanted noise. Dynamic microphones are less sensitive, making them ideal for loud environments.

Q. Can I record music with a smartphone microphone?

A. Yes, but the quality may not match that of professional studio microphones. Smartphone mics are improving, but for high-quality recordings, you may want to invest in a dedicated microphone designed for music.
