Here are 3 ways to use a lavalier mic with your iPhone or iPad.
1. RODE smartLav – $60, offers built-in TRRS 1/8″ miniplug connection. The first real lavalier mic specifically designed for iOS devices under $100. Note that the TRRS connection is not compatible with other 3.5mm / 1/8″ miniplug devices such as portable recorders, camcoders – we even tested it with the GoPro Hero 3, no audio is picked up – these mics are specifically designed with the TRRS connection to work with iOS devices. The smartLav is an excellent choice as it is less expensive and higher quality than other options.
2. KV Connection cable $29 + TRS Audio Technica ATR-3350 lav $22 Watch video on YouTube from user accceratemarketing Essentially this video is over a year old and offers a solution using the two items linked above. Unfortunately the inexpensive AT lav leaves a lot to be desired – it is very flat – lacking high frequency response which really provides the detail in a person’s voice. Note that using a different KV Connection cable, you can also add a higher electret condenser lav mics that require plug on power. Mics like much higher quality $199 AT899. Or any lav of choice with 1/8″ connector, popular choices are available from Tram, Sony, Sanken, Oscar Sound Tech, Countryman, DPA, RODE, Sennheiser and more.
3. MicW – $199, also offers built-in TRRS 1/8″ miniplug connection. See NAMM press release . Note that in addition to the omni version MicW also offers a cardioid lav. Cardioid lavs are generally used for sound reinforcement as they are directional – meaning they will pick up in the direction which the capsule is facing. This is great for avoiding feedback from large monitors in a venue. However, for most of us, we will want an Omni lav mic as the omni-directional mic will hear 360 degrees (all the way around in every direction). Even if the lav is accidentally bumped and completely inverted it will still sound the same. In fact, a lot of pros will intentionally mount omni lavs inverted to avoid plosives (gusts of wind) from the speaker’s mouth. The accidental gusts can cause a “pop” to mic and are something to be aware of.
