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.

Bought these as a replacement for my Sony's tips and these are better. Still for me these (L)are not big enough. I would need an XL size version.

This is the 2nd set of Memory Earphone Tips I have purchased from Dekoni. The first was for my NuForce EDC IEMs. The new tips are far superior to the provided silicone tips and provided a nice level of isolation for listening to music while traveling.

The 2nd set was for use with my Ikko OH10 IEMs. I was truly ready to send the Ikko IEMs back as my ear shape was just not allowing the stock tips to seal and hold the earphones in place. The short nozzle just would not allow me to inset it to a point where they would stay. I even tried the Ikko 'Planet' foam tips and while a bit better, actually hurt my right ear after extended listening sessions. I really wanted to give the Ikkos a fair shot given the rave reviews, so I thought I'd try a set of Dekoni tips before throwing in the towel. Boy am I glad I did!! The OH10s now fit comfortably and seal properly revealing a wonderfully extended and impactful bass -- all without sacrificing the wonderful mids and crystalline high-ends. Turned 'Meh' into 'Wow'!!!

Highly recommended if you believe you are not getting all out of your IEMs either comfort or sound-wise.
