So this gadget comes in handy when you are in a vehicle and traveling with a DVD player with one headphone jack. Especially with a childrens movie with a heck of alot of songs playing on high volume, yet all children are quiet. I am sorry, did you hear heaven harps playing because I sure did.

They use this to listen to themselves instead of listening to the playback outloud....YES...LORD...he loves me. I prefer them to go in the studio...outside...but NO...they would rather listen to their music in the living room or the den. Why me...why. Now my daughter she can do the ....oh back to the review. Overall it is an excellent gadget, I swear I love it. Trying to think of something else they can come up with to match it!
