A number of reviewers praised its crisp sound quality. Its USB and XLR connectivity gave reviewers flexible options when they want to connect directly to their computer or to an audio interface - which improves the sound quality of the audio input. Its a very directional microphone picks up precise audio with rarely picking up any background noise. Some reviewers mentioned it works fairly well when used as a boom mic for shooting videos outdoors. They also mentioned it doesn't pick up too many plosives so that a pop filter is not really needed as long as it's used at a certain distance.


Some users mentioned the stand wasn't sturdy and the USB connection was flimsy. They would use a different stand and USB cable that fits well with microphone.


This is a good entry level microphone if you are looking a versatile microphone used for both at-home and outdoor use.
