best zoom h4

I heard this coming from the bedroom the other day best zoom h4; I did not know what it meant so I asked my husband. He said it was a recording device he could use, when our children are in a band to record them and put the music on the internet for all to hear. I do not know what it is with him and our children playing in a bean because I have heard him singing in the bathroom and he sounds awful. I was laughing at him. He does not know how to sing.
