Digital to Analog Audio Converter with Bluetooth 5.1 Receiver,Digital Optical to 3.5 mm DAC Wireless Adaptor,Coax to Analog RCA 3.5 mm for TV, Gaming

I was not happy with this thing for a while, but I kept pushing and it finally straightened out… alittle.I use this to transmit audio from my TV to my Bluetooth earbuds.Here were my problems and their solutions:1. Connection: I couldn’t get my earbuds to connect.- Hold down the “Mode” button to put the device in transmit mode. The blue light will turn red. The device will then start looking to connect to your other bluetooth devices (such as earbuds). Make sure your earbuds are in pairing mode during this time. They will automatically connect to one another.2. Static Noise: All I heard was static when connected.- Place your TV audio settings to PCM output mode. I used the optical cable.3. Volume Control: I could not control the volume of the audio with the tv remove nor the device volume nob.- Unresolved. I have no way to control the volume of audio in my earbuds.4. Audio Delay: There is a pretty significant audio delay using the bluetooth transmit feature.- The audio delay slowly corrects itself after about 5 minutes of use.* 4 stars. It was pretty annoying to play around with just to get it to work with no volume control. I would not buy again, but I am not replacing it unless the volume issue becomes unbearable. [...]
