Dekoni Audio ETZ-MERCURY Premium Memory Foam Isolation Earphone Tips Mercury 4.9mm

I'm glad I got to see which size fits best. They are for my Sony Wh-1000xm5. They came with one pair of foam tips and I used them so much I had to get more. Glad I did.

Not bad, but uncomfortable for lengthy wear times. Decent isolation; darkened the overall sound off my Dita earphones

Decent, comfy, ear tips, that fit.

My old Fiio's silicone ear tips have worn out. 50% of the time the ear tip would stay lodged in my ear when I pulled the IEM out. I have other earphones and headphones to use so I have been putting off getting replacement tips for them. Well I regret that I put it off for this long. These new Dekonis have put them back in heavy use. A secure fit and solid seal put new life back in the old IEMs. I have a couple more neglected IEMs that are getting new tips to bring them back now. Shout out to Auido46 for getting me my order quickly despite me moving and having to change the address. Great service.
