Hello,
Just got my soundcore motion + today and upon powering it on I immediately noticed a hissing noise. I have updated it to the latest firmware. The noise still persists. Is this a normal thing or is because of defective hardware? I’ve tried moving it to multiple locations so I don’t think it’s because of interference. It also happens when Bluetooth is off and not connected to any device and also happens when connected with a 3.5mm connection.
