sivamaruthikatta It happens after firmware update and unfortunately, there is no way to roll back the firmware version. For me, I sent it back to the distributor to get a replacement unit and I haven’t updated the firmware version since

Same here! The hissing sound with ANC is so annoying, especially in quiet places. It’s so distracting that it makes me feel like it’s raining outside. I hope they fix this soon because it’s hard to ignore!
