Cheaper than Comply foam tips and works better too.
In comparison to the Comply's, the Dekoni compresses faster and fills again better than the Comply. It's slightly more comfortable than the Comply's and doesn't mess with the sound signature (it's slight, but still noticeable).
I'd prefer this not only for it's value, but because it's easier to insert IEMs with these. Also it looks a bit nicer than the greyed out circular tips.
Don't forget to check their fitting chart to see which ones fit for you. If you're unsure, you can always order the sampler (comes with S,M,L) tips to try it out.
