When choosing a lapel mic for a smartphone a number of things need to be taken into consideration, the most important one being the feature of producing good and consistent quality sound. The following a few features and their applications that you may consider when buying a lapel mic for a smartphone.
Unidirectional or Omni-directional microphone.
A microphone that has a 360 direction may be good while doing outdoor video recordings on one’s mobile. However, such a microphone may pick up unwanted noises and clutter from the surroundings which could impede the quality of the recording. Regarding lapel mic for a smartphone such mics would be unsuitable for carrying out an interview or self-recording. Abrasion with one’s garments would tend to produce unwanted sounds. In the case of a uni-directional microphone, things are much more favourable for the case of such a microphone, not picking up surrounding noises. Abrasion noises from the clothes are not audible. The quality of the recorded sound would be much better.
Microphone plugs inter-changeability.
These are made in a 3.5mm size and are for 3 different adaptations and are not interchangeable except in the case of a smart conversion adaption cable being added. A smartphone mic is not interchangeable with an apple phone nor can these be used for a camera or laptop.
There is a significant difference in the price of a mic with a metal and a plastic. Metal bodies are finished in high-quality chrome that gives a splendid appearance. In case of an etched metal microphone, such would be suitable for a person not wanting a dull finish to complement their attire. The natural metal body mikes have the metal in the mic feeling as if that was alive while plastic feels like a dead material as regards the “feel”. A plastic mike would be suitable for buildings with high-security metal detectors, like at airports. A plastic mike would not have to be stripped of a person’s body upon the frequent passage of security metal detectors.
Microphone clips & wire clips.
The metal clips are generally chosen over plastic ones because of longevity and aesthetics. Plastic clips can be used in areas where one has to be frequently scanned by metal detectors.
For the purpose of transmitting, receiving or recording that is often the case that the wiring is located on a person, usually in a coat-pant pocket or the like. In choosing a lapel mic for a smartphone, the recommended length of a wire is 1 meter to 1.2 meters in length depending on the height of a person as well as apparel pocket location. A wire shorter or longer than these dimensions would tend to be an obstruction to movement, a short wire making movements restrictive and a longer wire tending to curl up causing hindrance.
A frequency range of 20-20 kHz.
Mics with such a frequency range are considered good for sound cut off limits as they maintain a good audio range between the high and low audio cut off points
Low to high impedance.
The low impedance mikes being considered the better ones for the following reasons:
Less than 600 ohms, best in quality, however very steeply priced and better suited for the professionals.
Medium impedance 600 to 10,000 Ohms, giving a good overall sound, priced right for amateur use.
High impedance, 10,000 ohms and above, being lowly priced suitable for those with a limited budget
