You get what you pay for. This is a very cheap (thin plastic) item. After fully charging this "transmitter" and my Panasonic headphones, I was never able to connect them. The headphones work fine with my other bluetooth enabled devices (phone, smart tv etc) but not this one. They returned the money after 2 painful days. My advice: It's better to spend a little more and buy a higher quality device than those cheap Asian imports.
