Start by power cycling your HD4's by turning them off and then back on. From there:
- Check to make sure the speaker wire connecting the left and right speakers is connected according to proper polarity (Red to Gold, Black to Silver) on both ends
- Please make sure all of your connections are complete and all of your connector cables are in working order (you will want to swap out some interconnects to test for this)
- If you are using any wireless devices, preamps, or external DACs in line with these speakers, please remove the wireless device from the application (temporarily) and connect the source directly to the speakers
- Please try using each input available (mini-jack, RCA, USB, as well as Bluetooth), one at a time, to see how the speakers react. When testing via RCA switch the RCA jacks (red to white and white to red) to see if the issue remains in the same channel
- Try using at least one additional source to see if the problem follows
