When I used to sew on my Babylock Pro Line I can't hear others when I sew together with my quilting friends. After I got my Brothers Innov-is I can hear them but they can't hear me over their sewing machines. They have to stop to ask or answer questions or make comments. I can even talk on the phone and sew at the same time. This is very beneficial if you have a sister that seemed to have an uncanny ability to sense when you are sewing intently and call just to chat.
