One end of the first cable received wouldn't fit securely into our sound bar or TV (both Samsung). You had to apply quite a bit of pressure to get the 'good' end in, but we weren't prepared to apply more force to get the other end in and damage our new equipment. I emailed the seller, got a replacement and both ends are fine. The seller was great and I would buy another of these if I ever need one. Good value for money.
