Length:: 2:38 MinsThis might be the best Bluetooth headset on the market but I'll never know because I can't get the thing to charge. Check out my video and let me know if I'm doing something wrong.NOTE: In the video, I mistakenly call this product the "Plantronics Explorer 645." This is in fact the "Plantronics Discovery 645" I'm reviewing.EDIT 2011-05-25 17:14PST: Spoke to a Plantronics technical rep earlier today and he said it sounds like my charging cradle is defective. Judging by what others have said about theirs, I doubt this is the case, but I've contacted the seller to see about getting a replacement. Will check in later with another update.
