I have brand new X4's. I fully charged them, updated the firmware, and reset them a couple times.
As soon as they are powered on, there is a white noise/ static. It is very noticeable at lower volumes and in quiet spots in a song. After the music is paused, the static decreases after 2 seconds. After about 30 seconds, the static disappears completely. When the music starts up again, there is an audible click and then the song and white noise begin.
Is this normal? Not normal? It is quite distracting in a quiet environment at lower volumes. It isn't noticeable if there is enough environmental noise.
I don't think this is a Bluetooth thing because as soon as it is powered on, the noise is there, before anything connects.
