Review: Great replacement for Sony wf-1000xm4 - Bought the Sonicfoam tips based on very positive feedback and so far I'm very impressed. These were bought to replace the tips on my Sony WF-1000XM4, fit and comfort is excellent, I tested on a 4 hour train journey and I found the noise cancelling and sound quality to be at least as good as the Sony tips or possibly even better. Due to the more compliable foam on the Sonicfoam I found them easier to get an airtight seal and once fitted they felt very snug and secure. I ordered the medium and although they are fractionally bigger than the Sony the foam type used compresses more so the fit is spot on. Another point worth noting is that the Sonicfoam have a smooth shiny coating in comparison to the matt finish on the Sony, I think this will make the Sonicfoam easier to wipe clean !......they also fit in the charging case without any problem. If like me you are finding it difficult to obtain Sony replacements and are looking at alternatives, save your time and go for the Sonicfoam, they do the job brilliantly and are great value for money. It's too early to comment on longevity but Sonicfoam say a pair should last for 4-6 weeks, so having 10 pairs in the box I'm covered for at least a year. Thanks Sonicfoam I'm really happy with my choice :) Review: Buy with confidence - With several companies all selling foam ear tips, it can be a bit daunting working out which company and which product to go for. But I'd recommend giving Sonic Foam a try. Their details, advice and charts helped me to quickly identify which tips would best suit my Sony XBA-H1 earbuds. Impressive, given that these particular buds are over ten years old. Normally I'd test the waters with a sample pack of different sizes, but that's not an option here, so the charts and measurements were a big help. I went for medium sized tips, which arrived very quickly and securely within a plastic case, which conveniently has a slot for each pair, rather than lumping all twenty together. Sonic Foam currently have a promotion whereby if you send them some details of your order, they will send you a second set of your choice for free. The process was hassle-free and the second set arrived equally quickly. The tips were a bit bigger than the silicon ones I was using, so they required a little bit of manipulation to insert snuggly into the ears, but once they were in they felt reasonably secure. (Hint - try moistening them before squeezing them - they'll go in easier.) They don't totally isolate the outside world, but they do dampen down much of the back ground noise. I tried them out on a train full of kids on holiday, and was surprised how much of the racket they had reduced by the time I took them out! Audio-wise they're fine. I found they gave the bass a deeper and richer tone, but I did have to slightly adjust the treble upwards. No big deal really. And the comfort more than compensates for any audio tweaks. Foam tips are a very cost-effective way to listen to your music in a noisy environment, compared to the expense and hassle of recharging noise-cancelling earphones, and I'd recommend going with Sonic Foam for their high quality product and service. ## Features - A revolution in sound performance, with foam that expands at the perfect rate. - Enjoy crisp, clear sound and comfort for an all-day immersive experience. - Memory foam is a degradable material; each pair should last up to 4 weeks. - Designed specifically for earbuds with a speaker diameter of between 4.4 - 5.7mm - Available Sizes: Small, Medium, Large | Eartip Dimensions: S=11mm wide / M=12mm wide / L=13mm wide / Hight for all sizes 10mm (Dimensions indicated are approximate and may differ slightly) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09L7D1Z4V | | Best Sellers Rank | 12 in Headphone Earpads | | Brand | SONICFOAM | | Brand Name | SONICFOAM | | Colour | Black | | Compatible Devices | with SF2: Various Earphones - (See Compatibility List) | | Compatible devices | with SF2: Various Earphones - (See Compatibility List) | | Country of Origin | China | | Customer Reviews | 4.6 out of 5 stars 5,638 Reviews | | EU Spare Part Availability Duration | 4 Weeks | | Enclosure Material | Hypoallergenic Polyurethane Memory Foam | | Item Dimensions | 12 x 12 x 10 millimetres | | Item Type Name | replacement-earpads | | Item dimensions L x W x H | 12 x 12 x 10 millimetres | | Manufacturer | SONICFOAM | | Manufacturer Part Number | SF20001MB | | Material | Hypoallergenic Polyurethane Memory Foam | | Model Number | SF2 (see model list) / Medium (Ear size) | | Product Warranty | Other | | Unit Count | 10.0 count | | Unit count | 10.0 count | ## Product Details - **Brand:** SONICFOAM - **Colour:** Black - **Compatible devices:** with SF2: Various Earphones - (See Compatibility List) - **Item dimensions L x W x H:** 12 x 12 x 10 millimetres - **Material:** Hypoallergenic Polyurethane Memory Foam ## Images ![SF 2 - Image 1](https://m.media-amazon.com/images/I/61Z6SXD+T2L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Hi, just recently purchased the jbl reflect mini. will the large tips fit in the case?** A: Thank you for your question. The SF2 should fit on the jbl reflect mini true wireless earbuds. Unfortunately, our tips are not compatible with the current JBL True Wireless Charging Cases. **Q: Does the sf2 medium fit the earfun air earphones and case** A: Thank you for your question. The Sonicfoam SF2 does fit the Earfun Air, but none of the sizes are compatible with the charging case. We are however launching a new tip called the Sonicfoam SF4 that will fit the same earphones as the SF2, but that offers a compatible case fit. The SF4 should be available in the UK in October. The SF2 still offers the best isolation/sound due to the foam being thicker than the SF4, but if a case fit is important to you then the SF4 would be the suitable choice. **Q: Hello, when do you expect to have the SF2 in S size in stock?** A: Thank you for your reaching out. We will have stock again in the next few days :) **Q: Does the sf2 fit the taotronics soundliberty 53?** A: These are designed for the Apple EarPods v2 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great replacement for Sony wf-1000xm4 *by R***N on 18 May 2024* Bought the Sonicfoam tips based on very positive feedback and so far I'm very impressed.

The ear tips are a good fit and fit in the case. They are great for insulating outside noise as they are thick and a bit squishy as opposed to some tips that are just a bit of thin rubber material. I find each tip lasts for about 3 weeks before they start to sag or loose their shape, but that may be because of my ear hole size or the way I jam them right in to my ears. I don't mind this too much as there are 10 pairs in the box, so they last me for quite a long time before I need to reorder. The customer support service from the seller has been very good whenever i have had an incorrect size or any issues. I recommend these as replacement tips for Sony WF-1000 XM5. ## Frequently Bought Together - SONICFOAM Memory Foam Earbud Tips - Premium Noise Isolation, Replacement Foam Earphone Tips, 20 Pack for in Ear Headphone Earbuds (SF2 Medium, Black) - [6 Pairs] Earphone Tips New Bee 12pcs Replacement Earbud Tips Blocking Out Ambient Noise Memory Foam Earbuds Inner 4.9mm for in-Ear Headphones with 5mm-7mm Tips (Black, S/M/L) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/382656612-sf-2](https://www.desertcart.sc/products/382656612-sf-2) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-08-28*
