Upgrade your listening with SONICFOAM SF4 Large Black ear tips

Designed for earbuds with a speaker diameter between 4.4 and 5.7 mm, the SF4 tips deliver a fresh listening experience. This 10-pack (5 pairs) gives you multiple replacements to keep your setup performing at its best, while still fitting neatly inside most charging cases.

What makes these tips stand out is the way the foam works. The material compresses and then expands at a steady pace, helping you achieve a comfortable seal without excessive pressure. The result can be crisper highs, clearer mids, and a more immersive overall feel, especially during longer sessions or on the move.

Real-world use cases include daily commutes, gym workouts, and focused study sessions. The foam’s expansion behavior helps mold to the inner ear for a steady, secure fit that stays in place as you move. With the SF4 line, you can swap tips quickly when you switch devices or try a different size for a better match to your ear shape.

Key benefits you may notice

  • Secure seal and improved isolation without heavy pressure
  • Clear, balanced sound with an emphasis on detail across frequencies
  • All-day comfort with a soft, responsive foam profile
  • Compact design that remains compatible with most charging cases
