You might as well buy from one of the other many fake "genuine" headphone replacement sellers on here. First off I will talk about delivery time. I ordered this Oct 21 and did not receive it until 5th Nov.
I contacted the seller and left negative feedback on the 30th Oct. To their credit they got in touch to say they had sent it days ago and offered to send a replacement in case it had got lost. However they didn't, they started ignoring my emails instead. Then it finally turned up and I noticed the invoice had 29th October printed on it in the footer. So they lied when they had sent it, it took them more than a week to even dispatch.
Furthermore they are not genuine Samsung at all, they have round cables instead of flat and the wrong ear pieces. Having said that they are not bad quality, better than some of the other fakes I have had and at least have a bit of bass. I just would get them from someone else who doesn't waste your time.
