Why do my speakers connect but I have no sound?

Hello, please check: 1.Make sure the audio interface is correctly connected. 2.Turn the volume of both devices to the maximum 3.Try to pair with other devices to check if there is still the same problem After checking please feel free to contact us via email.

Unable to connect 2nd headphone. Followed directions exactly several times, but still can't connect 2nd headphone. Any suggestions?.

Now that I see the actual full question NO I DON'T THINK SO.

Can i use the aux input to connect my phone, so i can then transmit to bluetooth speakers? (i need to boost the phone's signal)

It should transmit any audio signal to Bluetooth devices (headphones, speakers, etc.), provided that the signal is inputted through either the 3.5mm aux input jack or the optical TOSLINK connection. If your phone does not come with a 3.5mm audio output jack, you have to buy an adopter cable.
