Hi there I too the clamp fitters away from my ehadphones and then I changed the head phones altogether. I think the clamps are for safety when attaching to a computer. But I charge my mini disc over night and it stops charging when it is charged. Note the message charging disappears. I do have a question thouugh where did you buy yours as I have one which I bought from ebay about a year ago and I am worried that I will never be able to buy one again as the mini disc is disappearing and I am devastated. Thanks Tracey
