This seems illogical... Are there various SF2 tip sizes... Is there such a tip as SF2-LARGE..? **Q: Do these fit the AirPod Pro 2 headphones?** A: Thank you for your question. The Sonicfoam SFAIR is compatible with the Apple AirPods Pro 1 & 2 (Generation 1 & Generation 2) **Q: Which size for kz zas?** A: Thank you for your question. The Sonicfoam model SF1 fits well on the KZ range IEMs including the KZ ZAS. **Q: Love these on my sony xm-1000 buds - could you suggest a fit for my pixel pro buds ?** A: Thank you for your question. The SF2 that is the recommended size to fit on the sony xm buds are also the recommended size to fit on the Pixel Buds pro. (Please do note however that our tips are not compatible with the charging case for the Pixel buds) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***. on February 11, 2026* ### ⭐⭐⭐⭐⭐ Review *by M***B on March 22, 2023* ### ⭐⭐⭐⭐⭐ Review *by G***. on January 26, 2025* ## 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? - 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.ro/products/487801077-sf2](https://www.desertcart.ro/products/487801077-sf2) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-05-03*
