I decided to go with the WS4's it was not a price choice because there is little difference in the price when your buying the detector (only a few dollars) I went with the WS4's as someone else mentioned because it gives you more future flexibility. The WS5's are a "one trick pony" whereas the WS4's allow you to go to a full headphone (Vance or Grey Ghost) at a later date if you choose. They both appear to be about the same price, and I can't comment on which is better because I have tried neither, but I will likely pick up one or the other later in the fall when its getting colder. My biggest concern with the WS4's was on the comments about them hurting the backs of your ears, so far I have not found that to be the case. I plan to pick up the module that allows plugging in regular headphones or ear buds along with a few other accessories over the next couple of weeks so I have that covered as well.
