Some adapters are for microphones with batteries, and others specify microphones with no batteries. Note that this does not appear to work on all devices and microphones, apparently there are some differences in impedance levels of the microphones that the phones can’t deal with.

External microphone through the headset port Especially problematic seems to be recording loud sounds, such as concerts, although even those capabilities are improving. Newer phones have two or three microphones, but differ quite a bit in their sound recording abilities. Microphones on various models of phones vary quite a bit. Also very handy is the ability to email the recording, or save it to cloud storage, such as Dropbox. Important things to look for in an app are the ability to: 1) adjust gain levels 2) change sampling rates 3) display the recording levels on the screen, so you can make any adjustments necessary and, perhaps not as important, 4) save the files to multiple formats (at least.
