Safety features in headphones seem rather lacking in general. Noise cancellation tech especially is prone to causing these sudden loud tones if you somehow manage to cause a feedback loop. I fell asleep with WH-1000XM4s once soon after getting them and was treated to deafening feedback at a very unreasonable amplitude. Returned them. Apple has actually been the exception there, not only do they limit the amplitude, they also detect feedback loops (also often caused by trucks backing up) and stop noise cancelling until the source of feedback is gone.
