Just wondering whether those with the frayed connectors are all plugging in the same way or not.
Are you having the cord come out from the connector pointing up or down?
It shouldn't matter, but if all of you have been in the habit of connecting the same way, it might be something for everyone to try and avoid.
It may be that if pointing up, the weight of gravity is dragging it out of the connector. If pointing down, it may be because the cable bends when it touches the desk that is stressing the cable/connector joint.
