Decided to try the Dekoni earphone tips after watching DIRECTOR’S GARAGE. The tips are really nice as they not only block outside noise well, but also feel very comfortable. These are my #1 ear tips.

Great quality but the largest size is a little loose in my ears. Snug enough to not fall out but not a perfect fit.

I am hooked on Dekoni pads and tips, literally every piece of equipment I own has them. Truly can’t beat the quality and Comphort. I highly recommend them to everyone I know.

Foam has somehow like weak memory, actually, after you shrink it, the tip will hardly rebound to its shape. I bought 3 pairs Large, notably one of these 3 pairs was even more defective than the other two (it won´t recover its shape, even if you wait one year, rather will remain exactly as you deformed it).
Finally, the L size is not even with the original L size of Sony wf-1000xm4 tips, it´s smallest thus there is no fit at all, no passive Noise Cancellation and all range of Bass frequencies are lost, also, because the hole and the plug-in plastic circle are built in a different position compared to the originals. In summary, I lost $50 including shipping.

Just love the way these foam tips can actually seal all outside sounds and help improve my Sony WF-1000xm4 noise canceling and sound. Will definitely buy another pair.
