Title: Constant Hissing
Review: Charges well, looks great, on off button easy to use, but it only works well if you sit still. If you walk, stand, adjust your head they start hissing. It's impossible to enjoy a tv program bc I have to constantly press rewind on my DVR. If you don't have a rewind button forget about using these.
