This is a high quality professional video microphone that sits on the top of the camera via a hot shoe. It is a great microphone for any film maker on a budget and it sounds far better that an built in camera mic.The box is very nice and from the box alone, i could tell this is a premium product. In the box you find the microphone itself and a wind filter. This microphone requires a cell battery and the great thing is that in this case, it is included. This is nice to see, as it means you can get up and running as soon as it is out of the box. To use the microphone you simply insert the battery, mount the microphone to the camera, plug the aux cable into the microphone port on your camera, turn it on and hit record - Just don't forget to turn the microphone on or you will have no audio!The microphone is very well built and fits nicely on top of the camera, it mounts to the hot shoe mount and secures with some locking nuts to keep the microphone still and secure., it is a nice size so it is sturdy. The cable is coiled cable so it is stretchy so there is no excess getting tangled, but at the same time, it will reach all camera ports so it's ideal.The sound quality of this mic is very nice, it is crisp and clear, and doesn't have any background noise.Overall, this is a great microphone for any filmmaker on a budget as it sounds better than any built in camera microphone and will improve any videos by far without breaking the bank! Amazing! very happy :)
