My mistake I did not read the reviews.  I needed this for a play my daughter has a part in and the sound equipment we have needed a microphone.  We were on a budget and well I should have saved my money.  I can use this to hear things like a head phone if I want to hold it up to my ear and listen like a headset but cannot get the sound to come out on any sound system I have used and I have 4 different ones that I maxed the volume out on with no luck.  Very disappointed in this particular Sony product...
