Why should I use lapel microphones to record the videos I upload to YouTube?
I could name you a lot of benefits that you will get if you record the audio of your videos with a good lavalier microphone, however, I am going to focus on the most important benefits, because that is what will differentiate you from the other channels, and will make your videos get more visualizations, that after all, is what all the Youtubers want.
Audio is sixty per cent of your production!
Some people say that the audio is 50% of a video. To my humble opinion, the audio is more than that fifty per cent, why? Very simple, when you watch a video if the image looks blurry, but the sound is of good quality, you will finish watching the whole video. However, if a video has an excellent image quality (4K for example), but has lousy audio, people will leave the video within a few minutes of playback.
Therefore, I always think that audio is essential. It is preferable to buy a good lapel micro first, and wait to buy a better camera later. Unfortunately, most people who want to start in the world of YouTube, they do it the other way around, they buy a good camera, and they think that the audio from the camera is enough to record the videos.
To avoid outdoor noise and wind
To record videos outdoors, there is nothing better than a lapel microphone to capture the audio as clean as possible, without so much external noise and, above all, preventing the wind from spilling into the recording. It’s advisable to buy a windshield for this type of microphones, to avoid as much wind as possible. Another trick that works very well is to introduce the lavalier microphone inside the shirt.
Here you can see and listen to a Youtube Direct that I made in Guadalajara to try the best mobile tie microphone, I speak of the Shure MOTIV MVL.

What do TRS and TRRS mean in lapel microphones?
I’m not going to write or detail how and why these connections exist; I’m just going to teach you to differentiate them and, above all, what each of them is for, although I think that in the image that I made, you can see it very clearly.
This type of 3.5mm mini jack connection is the one used in microphones for smartphones, you can see it, for example, in the best lapel microphones of current price (2017 – 2018): Rode Smartlav +, iRig Mic Lav, BOYA BY-M1, Shure MVL /A, Audio-Technica ATR-3350, among others.
Each metal part of the TRRS connectors are the contacts, and each of the stripes is the contact separators.
All TRRS mini-jack connectors are the same?
No. But do not worry, since all the microphones that I’m going to recommend in this post, I’m sure they’ll work on any Android phone unless it’s very, very rare. On iPhone and iPad you will not have any problem.
It is the one that generally comes in the headphones and, as you can see in the image above, only brings two black stripes (separators).
Can you plug TRRS lavalier microphones into DSLR cameras, compact cameras or camcorders?
Yes. For any microphone that is TRRS to work in DSLR cameras, compact or camcorders, you have to buy a TRRS to TRS adapter of good quality, such as the brand RODE SC3 (there are cheaper, but of poor quality, this is the best, since it does NOT introduce noise in the recordings).
I bought the mini jack extension cable for the RODE camcorder microphone since it gives me a lot of versatility when it comes to recording audio or recording outdoors with the lavalier microphone.
What parameters should I set when buying the best mobile tie microphone?
In the world of audio, many terms and parameters exist. If all you need is a good tie microphone for your mobile, I am convinced that you will not read thousands of forums and pages where they talk about each of these parameters, since the list is extensive. Therefore, I have drenched on the most critical parameters in which we should set when buying lavalier microphones or any other microphone that has a good quality.
What is the sampling rate?
The tracking frequency refers to the times per second in which the level of the digital signals changes. To make one, the thousands of changes per second that occur, make these digital signals become sound waves, which results in the voice in the microphones.
The higher the sampling rate, the better the audio quality will be. For example, a sampling rate of 22,050 Hz would be much lower than the sampling rate of 192,000 Hz.
In audio, always buy devices that have at least 44,100Hz. Be very careful if you purchase devices with a higher value than this one since there are players that can not with these values, therefore the standard is 44.100Hz.
I attached an image where they explain in a summarised way, but with many details, what is the frequency response in the microphones, something significant in these devices.
Polar patterns in the microphones
The extreme patterns in the microphones determine the sensitivity to the sound of the receiver, depending on the direction or angle from which the sound proceeds.
There are the following sound patterns:
● Eight-way or Bidirectional
Number of audio channels in the microphones
We all hear the word Mono and Stereo but … what does this mean? Well, although it seems easy, that it is, many people confuse these two words.
This means that the microphone only has 1 Audio Channel, although later, through software, it can convert this mono channel into stereo by duplicating the track. I do this with the WaveLab software, but you can do it with Audacity without any problem.
The stereo microphones are those that record the audio through 2 channels.
This characteristic determines the capture resolution of the audio caseñales, that is, the bits determine the dynamic range of the audio signal, or what is the same, determines the maximum and the minimum of the decibels that a message has to be recorded.
It’s a bit complex to understand, but if you take as a reference that the resolution of 16 bits is right, then up there will be better, like the 24-bit resolution, which is the one that is customary to use in the professional field since it offers the Best Quality.
Transmission speed (bitrate «Kilobits per second»)
This parameter, the bitrate, is responsible for defining the amount of physical space (megabytes) that will occupy each second of recording. To give you an example: 3 minutes recorded at 128kBit / sec. It will hold 2.81Mb of space on the SD card or hard disk where you save the recordings.
The higher the Bitrate with which you record, the better the quality will be. The Shure Motiv MVL microphone you can choose all these parameters since it has an app for IOS in which you can set the receiver to your liking.
In audio, it is known as decibels to the size of the volume or, to be more precise, to the intensity of the sound. So that you have it clear, I put this simple example to you: when everything is silent, with the absence of any source of music or noise, the level of decibels will be 0dB. At the other extreme would be the intensity of decibels that could break the eardrums and hurt you a lot, this intensity is around 130 and 140dB.
To give you an idea, the decibel level used in a one-on-one conversation between two people is between 10 and 30dB. Between 30 and 40 dB, the intensity is still low and is what we often hear in our environment.
Begins to be annoying from between 60 and 75dB, which is the intensity of sound that can throw a vacuum cleaner or dryer, for example.
What can I need a lavalier microphone for mobile if my headphones already have a receiver included?
I include this question because it is what my friends have done to me when I recommend recording the audio with lapel microphones on the mobile phone. The first thing, whenever I can, I make a comparison of the quality of audio on-site so that I listen to the reason why I always use to see me with a tie microphone in the meetings or parties that I attend (I’m the group’s weird DJ).
When they listen to the audio quality of the Shure MOTIV MVL microphone that I always wear, compared to any receiver integrated into the headphones, it is often enough to answer this question.
But there is still more since apart from quality, the versatility of tie microphones also plays a significant role:
● You can hide the receiver between the shirt to go without it in the shot
● You can protect the microphone from the wind by the wind filter they bring, which will make the audio much cleaner.
● By plugging the Rode SC6 adapter into the phone, you can connect two microphones and a headset to monitor the audio.
● With the microphone integrated into the headphones, you always have to wear headphones to talk, with the tie, you can hide wherever you want as they are omnidirectional.
What are the best lapel microphones for mobile?
We arrived at the end of the article. I did not want to say goodbye, without first recommending, what for me, are the best lavalier microphones for smartphones today. If you are looking for this type of receivers you will find an infinite number of varieties, but, unfortunately, the vast majority of these cheap cordless microphones are useless.
Up to the present, I have tried tie microphones of all qualities, in fact, the one I have better now is the Tram TR50, a lavalier microphone. Then I had to buy the transmitter and receiver Lectrosonics UCR201. But beware, you do not have to spend this fortune to get good audio on a mobile, and I bought it because it was for a family project, and we wanted to get the best audio quality.
For this section, I am going to recommend the Top 5 best lapel microphones for mobile phones that I have tried. As you know, I never recommend products that I have not tried before, and if a product I try is terrible, always or, at best, I never write on my blog about those products that are not worth it.
I am preparing a complete analysis of the five lavalier microphones for cell phones that I will recommend in this article. All the reviews will always carry audio files recorded with these microphones so you can listen to the quality that each of them emits. I will also record videos on my Youtube channel so you can look and see how they behave when doing live shows on Facebook and YouTube.
The first of the list could not be other than the magnificent Shure Motiv MVL. I hesitated a lot before acquiring this microphone, since there were very few references or opinions about him here in Spain, but, thanks to a professional audio friend who lives in New York, who was the one who recommended this brand and model, now I can record and broadcast excellent quality audio from my Android mobile.
I can assure you that it will be the best investment in a mobile microphone that you can make.
The best known. If you are looking for information about this excellent lav microphone for mobile, you will find plenty of analysis in forums and YouTube.
Soon I will make a thorough comparison between the ShureMotiv MVL vs Rode SmartLav Plus so that you can say which of the two emits the best sound. This comparison will be available shortly.
My humble opinion is that the Shure captures much less noise than this Rode, but I would like you to be who of the final verdict. Stay tuned for the comparison that I will upload to my YouTube channel.
This specific lav microphone for mobile is very versatile, and above all, it is the ideal option for all those who want to record from the mobile interviews, since it has an adapter included in the price with which you can plug in another microphone.
The only but I put, is that the cable is tiny, for it, the solution I found at the time, when I bought it, was to acquire the extension cable TRDS RODE SC1, with this TRRS cable solve all the problems in this aspect (remember not to buy poor quality or cheap wires, since you will lose quality and the audio files will be very noisy, always buy the RODE brand)
The Saramonic LavMicro also has excellent audio quality and is optimised, above all, to record the broadcast, which, when you broadcast on Facebook or YouTube, you can rest assured one hundred per cent that the audio quality will be good.
Account of the native form of connection TRRS, with which, you will not need any adapter to begin to emit life or to record videos from the mobile with audio of good quality.
This was one of the first tie mics I used. Although it does not have TRRS connector, TRS, I solved this by purchasing the Rode SC4 adapter. The other small drawback is that this microphone is very expensive in Amazon.
