Users have reported high cabin pressure when using their unit's ANC. It's a pressure-like feeling inside your ears when the ANC is on and is a similar sensation to when a plane ascends and descends. It's caused by your brain perceiving the lack of low-frequency sound as a pressure difference between the inner and outer ear, which can become uncomfortable. The cabin pressure of these headphones feels strong when their ANC is on. However, it shouldn't be an issue for most users unless you're already sensitive to ANC. In comparison, other ANC over-ears, like the Bose QuietComfort 45/QC45 Wireless, seem to have somewhat less noticeable (but still present) cabin pressure.
不知道楼主是怎么得出"软件优化然后迫使用户购买新产品是真的"这个结论的, 迫使用户买 QC45 吗?
