I have a set of Sentry ***CD earphones that I am trying to get replacement foam earcove...

After going to Walmart for the emplacement earpads for earphones the sell, I was directed to go on line to Sentry for them, no response due to it being a weekend. On Monday I called and was told to go to Amazon for parts, no luck there but contact Sentry since parts are made in China. I ws then directed to a web site for earphone pads but it wanted a part number and*or size in mm for the specificc pads and also all they showed were pads for Sony earphones altho I kept typiny in Sentry. I asked are they the same for Sentry as for Sony, no response so I flaked off the black plastic pieces that were coming off on my ears and said ***** it, I feel like a bouncing ball and don't think i will recommend Sentry or Amazon to anyone. You asked for my response and you have it and I had heard Amazon was great.
