When I adjust the HEDDphone, I hear a crackling noise. Is this normal?
The Air Motion Transformer squeezes air out of multiple Kapton-folds. Due to this principle, you may sometimes notice quiet crackling sounds while adjusting the HEDDphone to your ears. This happens when air pressure is applied to the diaphragm and does not affect the driver‘s performance. The crackling won’t appear when you have found your ideal listening position.
