flew on the A321 twice this weekend. Same carrier, same configuration. But going in row 1 and *zero issues*… APP3 worked like a charm and cancelled all unwanted noise nicely. Going back in row 10 and right next to the engines… once at cruise altitude the APP3 become unusable for me. Constant woooooosh woooosh noise oscillating up / down with ANC on. So noticeable that it kinda gave me a mild headache. It appears to me that the current FW struggles with cancelling out the engine noise which has slight changes in frequency due to auto-throttle at cruise speed and overcompensates or whatever. Row 1 is probably to far removed from the engines but right next to them the ANC goes wonky….
Hope apple will fix this with a new FW update ….
