We bought it to improve our simulcast of church service via zoom. It is excellent for holding the telephone and the Mike improves the audio. We still are working out placement and audio more difficult because feedback is after the service and the smartphone is smarter than me. The problem I have is when an a speaker comes in on zoom. I have to disconnect the mike or integrating a 2nd telephone. When we figure it out it will be great.
Increases volume and clarity over.phone mic of course. Notice must be given to push hard at mic cord input as it might not seat fully. Play store open camera app offers no adjustment for mic level.
