Product details

Overview

SONICFOAM SF2 Medium Black memory foam earbud tips are engineered for earbuds with a speaker diameter between 4.4 and 5.7 mm. The foam expands at a steady, deliberate rate to form a comfortable seal that supports crisp audio and a relaxed listening experience throughout the day.

What makes SF2 tips stand out

  • Controlled memory foam expansion helps create a stable, comfortable seal for many ears.
  • Designed for crisp, clear sound with a more immersive fit during daily listening or focus sessions.
  • Memory foam is degradable; expect replacements after roughly four weeks of typical daily use.
  • Three available sizes — Small, Medium, Large — with approximate widths: 11 mm, 12 mm, 13 mm; height around 10 mm.

Fit guide and sizing

  • Compatibility: fits earbuds with diameter 4.4–5.7 mm; check your model’s specs.
  • Choose the size that gives a secure, comfortable seal without excessive pressure.

Real-world use scenarios include daily commutes, office focus sessions, workouts, and long listening periods. The soft memory foam cushions gently, reducing ear fatigue while staying in place as you move. The pack offers a practical balance of comfort and function without locking you into a single fit.

Care and longevity tips: rinse or wipe gently as needed, avoid harsh chemicals, and allow tips to dry completely between uses. When performance changes, it may be time to swap for a fresh pair to maintain fit and sound quality.

Why choose SONICFOAM

These tips are designed with listening comfort and compatibility in mind. The memory foam’s soft, responsive feel helps you enjoy longer sessions without pressure hotspots. Pair with a wide range of in-ear buds to customize your seal and isolation.

Usage ideas

  • Daily commutes: a secure, comfortable seal for reliable sound and reduced external noise intrusion.
  • Gym or runs: lightweight, stay-in-place design that adapts to movement.
  • Office focus: a calm listening experience with less ear discomfort during long sessions.
