My Eris 4.5 BT sound great. However, when I put them in bluetooth pairing mode, I hear a very subtle static that repeats 4 times every few seconds or so. Figure it's sending/receiving a signal. When I connect the Eris to any device, the speakers emit a high-pitched crackling noise. It's not loud at all, but if there is no other sound coming from the speakers, it is very noticeable. Turning the volume up or down does not affect the cracking noise.
I've tried different outlets, power strips, devices, power cycling, no other BT devices in range... This is the second set with the same issue.
Is this just a noise that BT speakers produce? The speakers are wonderful and I'm very impressed with the sound, but the bluetooth function is unusable which was an important factor when I purchased these.
Anything else or suggestions I could try?
