Problem: Jabra directed me to these as a replacement for the lost pieces for my Wave. THESE ARE NOT what I need. Meh. Gonna be two more weeks before I get home to return them.I don't blame the merchant, blame Jabra for directing me to waste weeks buying, waiting for, and returning the wrong stuff. Swedish morons
