This product is really a piece of junk! It picks up EVERY sound in the room. It can not differentiate between sounds you want and don't want. it makes horrible scratchy/static sounds, you can hear yourself speak, chew, breathe...it pretty much amplifies everything LOUDLY! You cannot even move while you are using it...if you accidently move it or touch it...the volume of that sound scares you to death! In addition to all of the above, the quality of the sound is tinny and very poor. THIS IS A WASTE OF TIME & MONEY! Please take my word for it and don't bother, because you'll end up having to go thru the inconvenience of returning it.
