Q: How do these compare to the SednaEarfit Crystal?

I prefer these to the crystals. If that is you are referring to the zelastics. The crystals, or zelastics are incredibly sticky… which many people love. They are an eartip mad of a material I’ve not seen before. And it is incredibly sticky to the touch and very grabby. Many people really love them… I find it’s really hard to get them in and out of my ears. Once they’re in, they are definitely secure, they’re not going anywhere… that’s for sure. But I don’t like that about them, or the way they feel while In my ears either for that matter. They also have a smaller bore… which can increase the perception of bass… if that’s what you’re looking for they may work great. I prefer a wide bore tip… most of the iems I own and use regularly… have a level of bass Im happy with, and the wide bore seems to increase treble extension just a smidge… or at least the perception thereof. I prefer the regular Sedna ear fits. And I’d get the regular ones… not the lites. Don’t know why or if I’m hearing things… but I feel like the regular ones sound just a smidge better than the lights. Just my two cents.
