The default tips for thee xm4 are terribad in that they are a pain to get a snug fit and then super uncomfortable once you finally get one. These solve that problem and they are way more comfortable. I did experience some discomfort after awhile but I think that is due to trying literally every wireless IEM worth trying save the technics az60. I had thought the Sennheiser MTW3 that just came out would be the one but it just had a few quirks I didn't like and the ambient mode isn't as good as the XM4 e.g. noticeably more white noise. Once my ears heal from all the bad earbud fits I and tips I have tried I don't think I will even feel these. Long term durability I cannot speak for as I just got these in the past couple days. They are designed for like replacement every month and a half or so of constant use so that's to be expected I suppose. I haven't tried the XM4 comply tips but don't think I'm gonna. One thing I will mention is the default tips fit a little more snugly on the stems than these do but they fit snug enough I'm confident they will not fall out or pop off. I did quite a bit of eating and ran the fit test in the sony app, before and after eating, but they never budged. I wore them for several hours including talking, eating and generally moving around testing them every so often with the fit test to see if they budged, they didn't. No high intensity workouts yet but if they stayed snug opening my yap super wide to take bites of an oversized piece of banana bread I don't foresee a problem. Perhaps from constant impact force they might work lose, I haven't run in them yet but seems unlikely. I did some gun training with them in to see if they blocked enough noise with the default tips and even with a less than stellar fit never had them come out. These tips will keep them rock solid is my best. Review: A perfect replacement on my Sony WF-1000XM4 earbuds. Better than the junk Ebay ones - I originally made the mistake of buying "OEM" replacement memory foam ear tips on Ebay. They were neither memory foam, nor OEM. I had resided to thinking I'd be stuck with the cheap rubber tips I bought, when I finally came across these. They are a very close replacement for the original Sony tips, and fit great. They aren't quite as nice as the Sony tips, but are maybe 90-95% as good and far better than anything else I could find. They are comfortable and snug and sound great, returning the full bass effect I lost with the cheap rubber tips. Of the original Sony tips, I used the Large size, but on these, I am a Medium and the large is just a bit too big. I'm glad I bought the 3-size pack to confirm this as opposed to a 3 pack of the same size. Very happy to find something better than the junk tips I bought on Ebay, and I plan on buying a 3 pack of mediums when these wear out. ## Features - Precision Fit for Unmatched Comfort: Available in Small, Medium, and Large sizes, the Dekoni Audio Mercury Bulletz are expertly designed to provide a secure and customized fit for a wide range of in-ear headphones.

The Mercury earphone tips will work with the MEE Audio M6 Pro. **Q: If i order medium size only for sony wf-1000xm4, how many do i get for $20** A: 3, however, I would not recommend these, they're too long and will cause the headphone to be farther away from your head. **Q: Will these fit ikko oh1?** A: Yes. **Q: Mine keep slipping out. Thought it was wax, cleaned them, still do that. I use small, and wonder if this is normal?** A: If you use small tips to get the nozzle closer to your ear canal that usually means you either like low profile IEMs or you sleep in them. I use mediums with my IE80 that I sleep in & they never fall out. Get a multi pack & see which is best suited for the size & weight of your IEMs. Good luck. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Brilliant for the Sony WF-1000XM4 *by D***Y on June 15, 2022* Have been searching for an earbud that touches all the bases and fits securely in my ears.

But they are lacking a driver protective mesh and are incompatible with the Sony WF-1000XM6 charging case. The lid won't freely close whether these ear tips are on the buds. ## Frequently Bought Together - Dekoni Audio Mercury Bulletz Moldable Memory Foam Isolation Earphone Tips, Black, 4.9mm, 3 Pack (Medium) - Dekoni Audio Premium Memory Foam Earphone Tips for Apple Airpods Pro, Medium --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/82994871-dekoni-audio-mercury-bulletz-memory-foam-ear-tips-medium-3](https://www.desertcart.pt/products/82994871-dekoni-audio-mercury-bulletz-memory-foam-ear-tips-medium-3) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-02*
