I use the SF2-MEDIUM with my JBL T110. I receive a second set SF0-SMALL for providing user feedback. I use the SF0-SMALL on my Truthear Zero Red. [1/26/25] Easy 5 stars. I would not hesitate to buy these again. I bought the SF2 size in Medium for my JBLT110. Fit is perfect, they slide on firmly and do not fall off. Sound isolation is improved considerably. They feel like foam-roll hearing protection earplugs. They have much less "suction cup / vacuum" feel on my eardrums. The JBLT110 with factory silicone tips have a very pronounced 5~7 db treble boost above ~6K, that honestly sounds like nails on chalkboard to my ears. These sonicfoam tips help to tame that treble boost for an overall better sonic presentation. I am not new to in-ear monitors and foam roll type ear-tips. My first set of IEMs was a Sure E2C 15+ years ago and I have owned various models from various brands since.... Jays, Sony, Truth ear...etc. What's nice about these Sonicfoam tips is the foam expands slowly in my ears, so I can take my time inserting them. Its NOT like a beat the clock... quick before they re-expand kind of thing. [1/28/25] I received a second set as a favor for providing user feedback. This second set is a SF0-SMALL for my TruthEar Zero Red. The Zero Red is well known for having a HUGE sound output tube, almost 7mm diameter. The SF2 tip inside diameter is way too small. The SF0 fits the Zero Red perfectly. Not too tight and not too loose. They are very similar to the OEM foam tips, except the Soncfoam material expands much slower so I do not have to hurry/rush to insert them. As far as sonics and comfort go they are an exact match to the OEM foams. [2/20/25] After almost a month these foam-roll tips are still going strong. They do show very slight signs of wear, but nothing significant. They are maybe still a solid 95%, and they seem to have plenty of life remaining. I use the SF2-MED with my JBL T110 EVERY night to fall asleep listening to waves and rain forest sounds. I also use them during the day to listen to music and YT vids. I literally roll around and fall sleep ON THEM every night. No soreness or discomfort of any kind paired with the small JBLs. I have equally positive results with the SF0-SMALL on my Truthear Zero red. Although I don't use those nearly as often as the JBL T110. I will post a follow-up to this review if my opinions change. Review: Perfect tips for KZ ZS10 Pro X and JBL Vibe Beam for large ear canals - Finally found foam ear tips that fit my KZ ZS10 Pro X earphones without being loose around the headphone tip or inside my ear. I have large ear canals so these foam tips expand comfortably isolating external sounds giving my music a deeper bass sound than the original silicon tips, and no itch!. Best of all? the price, they're not as expensive as other brands. They also fit the JBL Vibe Beams, same fit and audio bass improvement, but just as all other earbud tips for these Bluetooth with a case, they don't fit properly, I have to remove them from the earbud so the lid closes properly to charge. Highly recommended. ## 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 - Fits Most Charging Cases - Available Sizes: Small, Medium, Large & Tester pack (S/M/L) | Eartip Dimensions: S=11mm wide / M=12mm wide / L=13mm wide / Height for all sizes 8.5mm (Dimensions indicated are approximate and may differ slightly) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CC11V9SN | | Best Sellers Rank | #3,854 in Electronics ( See Top 100 in Electronics ) #76 in Headphone Earpads #1,495 in Hearing Protection Equipment | | Brand | SONICFOAM | | Color | Black | | Compatible Devices | Earphones | | Customer Reviews | 4.4 out of 5 stars 5,501 Reviews | | EU Spare Part Availability Duration | 5 months | | Enclosure Material | Memory Foam | | Item Dimensions | 0.52 x 0.52 x 0.33 inches | | Item Type Name | replacement-earpads | | Item dimensions L x W x H | 0.52 x 0.52 x 0.33 inches | | Manufacturer | SONICFOAM | | Material | Memory Foam | | Mfr Part Number | SF60001LB | | Model Number | SF60001LB | | Unit Count | 5 Count | | Warranty Description | Other | ## Product Details - **Brand:** SONICFOAM - **Color:** Black - **Compatible Devices:** with SF0: Various Earphones - (See Compatibility List) - **Item dimensions L x W x H:** 0.43 x 0.43 x 0.39 inches - **Material:** Hypoallergenic Polyurethane Memory Foam ## Images ![SF4 Large - Memory Foam Earbud Tips - 5 Pairs - Black - Image 1](https://m.media-amazon.com/images/I/61g5V5TsiaL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5 stars easy, SF2 & SF0 *by G***. on January 26, 2025* I am a purchasing consumer posting an honest review of the SF2-MEDIUM which I bought.

As a former airline pilot, I've tried everything that you can stick in, on or over your ear to attenuate noise. I used Comply for years, and Sonicfoam completely blows it away! Superior noise attenuation, better fit, and stays in the ear better. I use foam tips for everything -- ear buds for music & podcasts, aviation headsets, and sleep devices like Ozlo and QuietOn. Sonicfoam almost completely blocks ambient sounds, while Comply lets some sound leak through. Also, among the best customer service of any company I've ever dealt. And a better price than Comply seals the deal! ## Frequently Bought Together - SONICFOAM Memory Foam Earbud Tips - Premium Noise Isolation, Replacement Foam Earphone Tips, 10 Pack for in Ear Headphone Earbuds (SF4 Large, Black) - Soundcore by Anker Space A40 Adaptive Active Noise Cancelling Wireless Earbuds, Reduce Noise by Up to 98%, Ultra Long 50H Playtime, 10H Single Playtime, Hi-Res Sound, Comfortable Fit, Wireless Charge --- ## 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.vu/products/604428684-sf4-large-memory-foam-earbud-tips-5-pairs-black](https://www.desertcart.vu/products/604428684-sf4-large-memory-foam-earbud-tips-5-pairs-black) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-09-21*
