Rode SmartLav+

You usually can't go wrong with Rode's products, and this one's technically not a bad one either. It comes with a nice leather pouch that has a moisture absorbing bag in it. The wire itself is made or coated with kevlar, at least that's what the warning label says. The cable indeed seems quite solid, even though it's pretty thin. Then the downsides: as so often happens with TRRS lav mics, it does muffle the high end a bit; on the other hand, your phone's preamp might affect tha too.. Rode's own TRRS-TRS adapter cable is sold separately, which is a bit of a letdown; the device should come with one from the get-go, as the cheap Behringer models that are meant for the same purpose include such adapter. At least on my Android phone, the mic takes over my phone's audio output completely, meaning that you might end up needing a separate splitter cable if you want audio out while the mic is attached. The microphone itself is pretty good for field recordings where you need isolation from surrounding sounds, echoes, etc, and it does make the speaker's voice quite clear and pop-free. One should also note that the recording app that Rode offers for this mic only works on Apple phones, which also is a bit of a bummer, since the mic's high-end drop isn't anything drastic, you can fix it with a marginal EQ adjustment. Anyway, it's a good Rode-quality product with some minor downsides, and be aware that you'll need to figure out your audio output cabling/routing if you're using it on a phone (or at least on an Android one) and need audio out while recording.
