Neewer CM14 Video Microphone (3.5mm) - $14.00 + Free Shipping w/ Prime or $25+

Terrible Product. The iPhone inbuilt mic has way better quality than this tin-can mic

Decent little mic IMO. I have 3 of them, and I use them for interviews and events with my DSLRs (video work).

They're not *PRO* sounding, but they are:
Better sound quality than the built in mic
Small and easy to carry
Comes with dead cat and accessories
Doesn't require batteries
Comes with cords for both DSLR/Mirrorless and Mobile
CHEAP

I can't say how it works on mobile cause I've never used it for my phone, but it is a cheap/lightweight upgrade from your camera's built in mic.

If you're looking for an inexpensive mic, search for reviews for the TAKSTAR SGC-598. It goes for about the same price on sale..

I have this and the TAKSTAR. Honestly, this mic is really good for the price (IMO). I like it better than the Rode I had previously. Seems to perform well overall, and definitely an upgrade over built in mic on cameras. Might not be worth it for phones, as many have fairly good mics already.

What's good for recording in a noisy room?

Quote from 1wondershow : What's good for recording in a noisy room?

Understanding microphone types can be very helpful. This is a cardioid/"shotgun" mic, which means it is directional - it picks up sound from the front, but is good at rejecting noise from the sides and the back. This can be very useful in a noisy room is you are able to point it directly at your subject without any other noise sources also being in the path of the pickup pattern. Since noise bounces off walls, this can be difficult to get just right. That's why you often see these types of mics, albeit much more sophisticated and expensive, used on boom poles pointing down directly at a talking subject. It can be kept out of the shot while not picking up noise behind the speaker.

That said, if it doesn't matter that a mic would be visible in your shot, a lavalier mic might be a better choice. Also called "lapel" mics, these are the ones that clip onto the clothes directly below the speakers face and only pickup sound from very nearby, which helps them reject all noise from sources further away than the speakers mouth.

I have 3 of these exact mics. Neewer QC can be so-so, but for the price these can't be beat. Rode sells similar mics for more than 4 times the price that honestly aren't as good. Anyone who's had problems with this mic either
A) got a bad unit,
B) Isnt using it correctly,
C) Has unrealistic expectations of a a DIRT cheap cadioid mic.

Hope this helps.
