Has anyone here bought and used the Quattro listening device for their hearing aids? It's something you can put next to your TV or phone or on a table if you're eating in a restaurant--all to assist you in hearing better if you're wearing hearing aids. It sends a signal directly to the hearing aids to improve hearing--that is what is advertised. I'm seriously thinking about getting one as an audiologist who has one and even has a cochlear implant says he's very happy with his. Andone here have any experience with this device or any other one that they know of that is similar? Thanks.
