I have two headeets connected on maz volume and its still very quiet.** A: I don't have this problem, but I can suggest two things. The first is to try to increase the volume on the transmitter by pressing the + or ^ button on the front section of the transmitter. The second it to try to increase the volume of the input source feeding the transmitter. **Q: I have an outdoor weather station that connects with Bluetooth to an indoor tablet would this device boost the distance I can locate them apart?** A: Sorry, the B03 only supports audio output or input via Bluetooth (one of two modes) **Q: If in Bypass mode. If i plug into the sound bar and use one bluetooth device. Will i get a delay on the bluetooth speaker?** A: Bypass connects an input directly through to the connected output, and the B03 will neither transmit nor receive. **Q: I plan on using my 3.5mm line out on my DAC to the line in on this device. In transmit mode will my DAC volume control be passed along to the speaker** A: I am using my stereo systems headphone output to power the bluetooth transmitter. The system's volume control is definitely reflected in the earphones. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well *by M***T on 22 February 2024* Used to transmit my turntable output to bluetooth speakers, as well as pass-through to my soundbar.
