In order to get the finest quality from a avalier microphone for iPhone® Lightning, it's vital to consider its distance to your sound source. Most lav microphones have an omnidirectional capsule, which means they capture sounds from each direction equally and are hence very forgiving while recording. However, as a general rule, the mic should be placed on the chest, approximately a hand's breadth (20-30cm) away from the talent’s mouth. This will provide an uncolored and natural sound.

Attaching the lav mic to its clip

All lavs come with a clip that you can use to attach the mic to the clothing. These clips might be a bit difficult for first-time users, but they are really simple to utilize. Just remove the windscreen, pinch the spiral clasp, slide your mic into the loop, and release the clasp. And now you can mount the windshield back.

Mounting your lav according to the types of clothing

It’s simplest to place a wireless lavalier microphone for iPhone® and iPad to an edge of clothing, such as the seam of a button-up shirt, the lapel of a jacket, or the edge of a tie. Just make sure the mic is free of any clothes that could rub against it, or it will damage your recording.

Things can get a bit trickier if you're wearing clothing that doesn't have a firm seam for mounting, such as a singlet or t-shirt. You can put the mic on a neckline, but keep in mind that if it's too close to the neck, the sound will be coloured and odd. Avoid this by wearing a looser neckline or positioning the mic to the side rather than right beneath the chin.

The shoulder straps are another ideal spot to install a wireless lavalier microphone for iPhone® if you're wearing a singlet. If you're wearing athletic attire, this is generally the best option. If you want to be more creative, you can attach the mic behind a headband. You'll get an excellent outcome if the mic is 20-30cm from your mouth and there are no clothes rubbing against it.

Four tips to connect wireless lavalier mic to your iPhone®

The next step is to connect your wireless microphone for iPhone® once it has been placed and positioned properly.

Accessories are needed if connectors don't match

The accessories needed to connect an external microphone to your iPhone® may differ depending on the model you have. Both the Lightning and headphone ports can be utilized for audio input if you have an iPhone® with a 3.5mm audio jack. If your iPhone® just has a lightning connector and no headphone jack, you'll need to use a few adapters.

iPhone® requires TRRS plugs for audio recording

Even though your iPhone® has a 3.5mm jack, it won’t capture audio with every mic featuring a 3.5mm connector. iPhones often allow TRRS (tip, ring, ring, sleeve) 3.5mm headphones. You can also listen to music on your iPhone® by plugging in a headset with a 3.5mm TRS connection.

However, if you use a wireless lav microphone for iPhone® with a TRS connection, your phone will not recognize it, even if it is plugged in properly. Instead, the iPhone® will use its built-in microphone to record. Because the electrical connections do not line up or the audio does not transmit in two ways, a TRS plug will not operate with an iPhone® for audio recording.

Most microphones with a 3.5mm connector, thankfully, support the TRRS standard. As a result, if an external microphone says "iPhone® compatibility" in its product description, you can be very certain it utilizes a TRRS connector.

Use adapters to connect microphone with TRS/TRRS to your iPhone®

If the lavalier microphone for iPhone® wireless you're using has a TRS audio connector and your iPhone® has a 3.5mm port, put the TRS audio connector into a TRS-TRRS adaptor. Connect your iPhone® to the other end of the adaptor.

If your iPhone® doesn't have a standard audio jack, connect the microphone (as described above) to a TRS-TRRS adaptor, then to a Lightning to 3.5mm audio jack adapter. The Lightning side of the adapter will connect to the lightning port on your iPhone®.

If your external microphone has a TRRS connection, you may skip the TRS-TRRS converter — regardless of the iPhone® model you're using.

Plug and play with Lightning connector

Using an iPhone® wireless microphone for video is really simple. Simply insert it into the charging port, and your phones will recognize it as the default audio recording device for capturing voice. And then you can begin recording.
