Some users report experiencing headaches or a sense of pressure when using noise-cancelling headphones. This is often related to the sensation of "ear fatigue" we discussed earlier. The sudden absence of low-frequency noise can feel strange at first, leading to discomfort for some people. However, these effects are typically temporary and often diminish as you acclimate to the technology. If you consistently experience discomfort, try different models, adjust the fit, or use variable ANC levels to find your comfort zone.
