I'm speaking strictly of imbalance though.
Vacuum sealed earphones can sometimes restrict the movement of air, and hence vibration/sound, on the tympanic membrane. Vented iems relieve that pressure, but sealed iems do not. If your ears cannot naturally relieve that pressure, then the way you perceive sound will be different.
Foam tips circumvent the issue because they do not seal in the same way that silicone tips do. They seal by occluding the ear canal without having to induce any suction.
Either way, I'm just sharing my 2c and what's worked for me with iems like the Tenore, FitEar TG334, Noble 6, ER4S, HF5, and others like them.
Hope it helps someone.
Yeah mate, i am not disagreeing with you. I don't doubt that some members might confuse vacuum seal issues with hardware failure, but when people like @gnarlsagan that also have experience with Ety iems complain about channel imbalance, i reasonably conclude that they are actually describing a h/w fault.
