Hi there, I'm hoping to get some opinions on something I've encountered with my pair of K701's recently - any help would be really appreciated.
I've been doing some tests using sine sweeps and have noticed that playing very low bass at very high volumes results in both the left and right ear cup vibrating and rattling against my ears, and a knocking sound to accompany. This disappears as the bass becomes higher. Please note that this isn't distortion or clipping, it's the drivers physically moving and resonating. It also won't be a hair or anything like that, I'm sure it's down to the power and depth of the bass itself.
Now, is this vibration/rattle of the driver and casing to be expected when pushing the headphones like this? One sign that perhaps it's normal is that the vibrations occur in both left and right earcups, and it seems unlikely that both would be defective.
I can reproduce this in certain music with very low bass but only at very high volumes. Low bass at normal to high volumes in music will occassionally produce a feeling of vibration against my head but without much of an audible effect in itself.
Any opinions would be great
Thanks
