This microphone is well made despite critics saying it with a background noise. To assess the level of noise it should be connected to a good quality recorder (H2n or otherwise), and see the level with audio software such as Audacity (free) who will eliminate the background buit. See also the only camera noise because it is often important. Takstar for the two capsules are medium performance but can be changed for more powerful (electronics store). At this price we can already achieve good short recordings.
