I haven't had an issue as I got mine with 1st shipment preorder as well. However if Samsung halted production it is obvious there was a quality issue at the production level therefore in general all products pushed out under previous production should be recalled/replaced. They didn't halt and "improve" the quality based upon "one offs". Just inquiring if there has been an announcement that I missed regarding Samsung addressing the current customer of the product.
The primary concern was with the earbud tips, as they repeatedly tore off during replacement attempts due to their adhesion to the earbuds themselves. If you have not encountered this issue, then it is unlikely to affect you. However, if you wish to seek assistance, you may visit a Samsung store for potential support.
