Below are excerpts from the review:
There is no arguing that you likely wanted a pair of silicone eartips to live forever, but let’s be honest, this was never going to be a thing, so the next best thing is to get the best silicone eartips you can grab, and ddHiFi offers an excellent choice with their ST35, having both a strong package, even a little case for the IEMS, and a nice design, with he best comfort I tried to date for a pair of IEMs. If your eartips did survive for longer, it is likely a much harder type of silicone, which based on the emails I read from everyone, and based on the comments I received on Youtube Videos and here on Audiophile-Heaven, is a problem for some people, so if you can use ultra hard silicone eartips, they may live much longer, but if you can’t ST35 is the best I can recommend.
