What are phone microphones?

The recording device for mobile phones has a big feature, that is small size, that is because the characteristics of the phone itself are portable and compact for daily use and carrying. The mini microphone for cell phone generally can be divided into three kinds: lavalier type, shotgun type, and they look like sculpture type. The first one is the most common kind that so many vloggers on YouTube and Tiktok are using them. A lavalier mic sometimes referred to as a lapel mic, collar clip mic, neck mic, or body mic, is typically worn as a bodyworn mic someplace on the speaker's body. While the performer or presenter is performing, they enable them to wander about freely. The nearer to the source, the sound is better.

Five things to look for in an ideal phone microphone

1. The Right plug - How to connect mini microphone to phone?

Broadly speaking, there are two ways, one is the transmitter using Bluetooth tech directly connected to the phone. This way you need to open the Bluetooth receiver settings on the phone in advance. But the Bluetooth wireless system can only work within a certain distance. So the one you need might separate into two parts of receiver and transmitter, which can greatly expand the range of the recording activities. While walking hundreds of meters away and talking, the mini phone microphone still maintains clear and stable sound transmission. And the way how to connect the receiver to the phone is to plug in, connect, set up, and record through the appropriate jack. Android phones use the traditional USB interface like Type-C or the new one called USB-A. iPhones use the lightning port for input and output. There are some with TRRS 3.5mm ports. Once the receiver and phone are successfully connected, then turn on the transmitter, pairing quickly, and you can start your videos. 

2. A Rugged body – Can it handle different extreme environments?

Some people will have specific requirements for the strength of construction of the mic, such as shooting in sub-zero temperatures, or the need to shoot extreme sports, such as parkour, climbing, cycling, etc., not only some of these, many times you will need a mini microphone that plugs into phone which is sturdy and lasting enough, worth your money and can be used for your shooting for a long time. After all, no one wants to buy a mic that is fragile and easily broken.

3. Sensitivity - Why does my phone microphone sound muffle?

If your recorded sound seems muffled, it proves that you need to buy a professional external mic for recording. If you still can't hear it clearly, it means that the one you bought does not have high sensitivity. It is one of the important features, which is attached to the product data sheet, so you can easily find it. For example, the table for SYNCO G3 portable microphone for vlogging with phone is marked with”-28dB (±3dB, re 1V/Pa at 1KHz)”. A sensitivity rating indicates how powerful the output signal will be at a specific sound pressure. What is a decent rating for sensitivity? Depending on the use, a strong mic sensitivity rating may be required. More gain is needed to get the mic signal to line level the lower the sensitivity. A 16 mV/Pa mic sensitivity would need 60 dB of amplification to achieve a line level at a conversation level of 70 dB, which is a decent rating.

4. Signal-to-Noise Ratio (SNR) – Why is it mostly recording the speaker’s voice and not noise?

A wireless LAN connection's performance is directly impacted by SNR. Larger SNR values indicate that the signal strength is stronger relative to the noise levels, allowing for higher data rates and fewer retransmissions, which together improve throughput. In general, networks that utilize speech applications should use signals with an SNR value of 25 dB or higher, whereas networks that use data applications should use signals with an SNR value of 20 dB or more.

5. Polar Pattern – How does it capture your sound so accurately?

Portable phone conference microphones have a certain trajectory to pick up sound, which is the key to a good external mic capturing your sound more accurately than built-in ones. Different trajectories form different specific types, divided into three categories like cardioid, bidirectional, and omnidirectional. The third one is the pattern of most of the wireless lavalier kind.
