Ear Plugs are a life saver when trying to sleep while your better half is driving and listening to the comedy channel. Imagine you are sleeping away and you cannot hear the XM Radio but all of the sudden you hear great shouts of laughter. I have thought of strangling him but then would have to run solo and that is not an option. We have purchased the cheap little ear plugs and they are great. Very little road noise, very little rattling, and just some back ground laughter at times. Give them a try and see what you think.
