Product details

Upgrade your listening with SONICFOAM SF3 small black earbud tips. The memory foam expands at a measured pace to form a snug seal, helping you experience crisp sound and comfortable wear during commutes, workouts, or quiet moments at home. These tips are engineered for earbuds with a 3.3-4.3 mm speaker diameter, delivering a balanced mix of fit and performance without sacrificing clarity.

Each package contains 20 tips, equivalent to 10 pairs, giving you a ready supply of replacements as your needs change. The foam is designed to be practical for daily use, with a typical lifespan of up to about four weeks per pair when used regularly. This provides a convenient cycle for refreshing your ear tips as your listening routines evolve.

Why choose SF3 tips

  • Foam expands at the right rate to create a secure seal and improve listening comfort
  • Crisp, clear sound paired with comfortable all-day wear
  • Memory foam degradation is gradual; plan for periodic replacement (about four weeks per pair)
  • Specifically crafted for earbuds with a 3.3-4.3 mm speaker diameter
