Review: Qualité / confort exceptionnels - Il est très rare que je laisse des avis mais je me dois d'en laisser un sur ces embouts d'une qualité et confort exceptionnels. J'ai quelques modèles d'IEM dont des KZ ZS10 Pro 2 qui m'étaient très inconfortables, j'avais mal aux oreilles, j'ai failli les retourner mais j'ai préferé commander ces embouts. Je ne regrette absolument pas cet achat, j'en oublie même que je porte des IEM, l'isolation sonore est parfaite et on obtient des basses profondes. Le seul petit bémol est qu'il est assez difficile de mettre les embouts sur les IEM mais une fois que c'est fait on en parle plus et c'est que du plaisir !
Review: Great comfort and with with a small compromise. - I just bought these. There was nothing stating that they would fit the jbl tour pro 3. I took the risk of buying them in the hopes they would. They do fit, they take alittle bit of manipulation to close the case lid. The smaller sizes may fit better. That side of things aside the tips are extremely comfortable. The quality of noise cancelling with these vs the foam tips that come with the earbuds is night and day difference. The way they sit in my ears is night and day. I did not have to adjust how they sit once, I am yet to wear them for an extended period (only 2 hrs) but i feel i will quite easily be able to wear them for the 8-10hrs i usually wear them for in my excavator. Overall i am very happy with these tips, i highly recommend them.

## 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)

### ⭐⭐⭐⭐⭐ Calidad de sonido y aislamiento
*by A***Y on 12 August 2026*

⭐⭐⭐⭐⭐ Excelente compra Las he probado con dos IEM diferentes (Audio-Technica E70 y StageDiver SD2) y estoy muy satisfecho. Son muy cómodas, aíslan muy bien —incluso ligeramente mejor que las Fischer Amps— y, en mi opinión, suenan claramente mejor que las Comply y al menos igual de bien que las Fischer Amps. Son un poco más largas que las almohadillas de espuma Fischer Amps, con un diámetro prácticamente igual ( el diámetro de la boquilla es más estrecho) Para mí, ofrecen una combinación excelente de comodidad, aislamiento y sonido. La única pega es que quedan bastante tight al colocarlas, especialmente en el SD2, porque tienen una boquilla estrecha, pero a la vez elástica. una vez instaladas quedan perfectamente sujetas. Cinco estrellas y compra totalmente recomendable.
