SONICFOAM SF4 Medium Black Memory Foam Earbud Tips (4.4-5.7mm) – 10 Pack, 5 Pairs, Fits Most Charging Cases

Experience a new level of comfort and sound with SONICFOAM SF4 Medium Black earbud tips. Crafted for earbuds with a 4.4-5.7 mm driver size, these memory foam tips adapt to your ear canal for a snug seal and immersive listening.

Why memory foam matters

Memory foam cushions and contours with every insert, reducing pressure points and helping the tips sit comfortably in your ears. The result is a more stable fit, less movement, and a listening experience that feels more intimate with your device.

Key benefits

• Foam expands at an optimal rate to form a secure, comfortable seal.
• Expect crisp, clear sound and a comfortable wear for long listening sessions.
• Memory foam is degradable; each pair is designed for about four weeks of daily use, depending on care and frequency.
• Designed for speaker diameters between 4.4 and 5.7 mm; compatible with most earbuds and charging cases.
• Available sizes S, M, L and a tester pack; dimensions roughly S 11 mm, M 12 mm, L 13 mm; height 8.5 mm.

What you get

• 10 tips total: 5 pairs in varying sizes for a personalized fit.
• Pack designed for quick swaps and easy replacement in a charging case.

Usage and care

For best results, gently insert and twist to seat the foam, then remove and let air dry after use. Cleaning is minimal, and the foam is designed to maintain its feel over time with regular care.

These tips are designed to complement daily routines—commutes, workouts, and desk listening—without making guarantees. Individual results vary based on ear shape, device, and usage patterns.

Designed for everyday use

Whether you’re commuting, exercising, or winding down with a podcast, the SF4 tips aim to balance isolation with natural situational awareness. The foam’s warm, yielding feel can help reduce fatigue during longer listening sessions.

Fit, compatibility, and care notes

Fitting works with earbuds that have a 4.4-5.7 mm driver and most charging cases. To maximize life, avoid soaking, and replace tips when the loft diminishes or the fit becomes loose. Regular light cleaning helps maintain loft and comfort.
