I have this Bluetooth adapter purchased mainly to connect my Bluetooth headset with my TV. For this adapter is unfortunately useless. When I connect this anchor Bluetooth adapter into the headphone jack of my TVs and Kopple with my Bluetooth headset, I notice a significant delay between picture and sound. That bothers already when watching newscasts. In movies it disturbs of course the more. By comparison, I have connected to my Amazon Fire TV the same Bluetooth headset, and noticed no lag even after hours of watching movies and series.
The unit goes back to the seller, and I have to dedicate more time to find a usable device. Pity about the time.
