Hi there,
I read on here a few times that some people couldn't find the link to claim their free Samsung silver buds, so here it is.
Just enter your details, take a photo of your Delivery note, and enter the IMEI on the wee sticker on the back of the Tablet.
Once sent you should get a text saying that your claim has been verified and you should receive your buds within 45 days..
Hope this helps...
