If I grab it other ways it will show a pulse reading but rarely change. ♥️♥️♥️ I really hope Plantronics comes out with some new gaming headsets similar to this, but perhaps with a more sturdy mic structure. Just the key holder with a tag on it. Reminds her of the days when things where made with pride. It makes all the difference. I have other bluetooth buds and cans and they have occasional and persistent issues with connectivity. See the pictures for the difference (not great photo quality and my old ones look kinda gross I know hah)I was hoping they may just have been a poor product from Amazon but I checked the product on the Reef website and saw that the photos do match this exact new design (at least back part of the shoe is identical). These are the flimsiest, cheapest things I’ve ever bought. Doesnt come with overall instructions in the kit but thats okay.
