Review on 🦈 Vdera SF-E-11-AMZ Sharkfin White Self-Molding Earbud: Unleash the Perfect Fit for Ultimate Comfort by Scott Bailey

Is it suitable for holding headphones? Yes. Does it block any noise? Not really. First, the instructions are tiny. They should be at least twice the size, the photo shows almost no details. As a result, I opened the video online, which is better. Instructions for putting on the headphones are sparse in either case. I found that after failing two of these I used the leftovers to try something different, keeping the shape more on the actual bud and sealing the ear canal a bit, which blocked the noise better. But even with the best method, they do a poor job of canceling out noise, less than just a comfortable earbud. They do not seal your skin and therefore do little for soundproofing. That's the whole reason I wanted her. The claim that Sharkfin deadens outside noise is false advertising. If you just want the headphones to stay in place (exercise?) they seem to work well, but don't count on the extra noise-cancelling from them.
