Review: Gran mejora en auriculares in ear - He comprado estos tips para auriculares B&W pi8, sennheiser momentum tw4 y beoplay ex. Se ajustan a la perfección (gracias a las indicaciones y compatibilidad de diámetros de distintas marcas de auriculares, de gran ayuda).

## Questions & Answers

**Q: Are these earbuds able to reduce noise leakage?**
A: I own Sony WF-700B earbuds... the chart suggests SF2 tips based on speaker tube size, locking every customer into the same ear canal size..? 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)

### ⭐ Não recomendo
*by F***T on 9 May 2026*

Essas são as piores espumas que já comprei, não consegui usar pois só de colocar elas no fone elas já rasgaram. Horríveis, super frágeis, rasgam só de colocar a mão.
