I have purchased 3 sets of the Logitech Freepulse wireless earphones. Over time, they all wore out and split in the middle of the headband, making them useless. I kept all 3 pairs and sent them to Logitech a month ago with a letter asking for a free set. I know they got the package - they signed for it. I also know they haven’t responded - even with a "***". Calling them is beyond useless, they act like I am the only person this has happened to. And don’t bother asking me why I kept buying a product proven to fail. I can’t answer it. Sometimes I'm not too bright.
