Review on PROZOR Digital to Analog Audio Converter with Optical and Coaxial Inputs - Convert Digital Audio to RCA L/R, 3.5mm, and Optical Out by Elder Unogu

I output sound from Prozor optical audio to my soundbar but the reason I bought this is so my wife can hear the soundbar while my hard of hearing ears wear my Sennheiser wireless headphones RCA or 3.5 can carry headphone inputs. I contacted the seller and initially they responded and made me several suggestions none of which changed anything and said they would send me a replacement if we couldn't get the Prozor to work. But they stopped communicating and never sent me a replacement. So I'm sending it back and ordering again, hoping the first one was just defective. If the new one works I'll change my estimate.
