SONICFOAM Memory Foam Earbud Tips for Buds 3 & 4 Pro — 6-Pack (S/M/L Black) — Improved Seal & Noise Isolation

If your earbuds feel loose, uncomfortable, or leak sound, these replacement tips give a quick way to restore a secure seal and clearer audio without changing your earbuds. Each pack contains three pairs (small, medium, large) in black, crafted to fit inside the charging case and engineered to expand at a controlled rate so the foam conforms to your ear canal for a snug yet gentle fit.

How do these tips change sound and noise isolation?

Memory foam creates a tighter seal than silicone, which reduces outside noise and directs more of the speaker’s output into your ear. That improves perceived bass and overall clarity without altering the earbuds’ tuning.

• Improved passive noise isolation for clearer listening in noisy places.
• Tighter seal enhances low-frequency response and bass impact.
• Foam expansion fills gaps that silicone tips often leave.

Will they fit my Buds 3 or Buds 4 Pro and the charging case?

These tips are shaped for Buds 3 and Buds 4 Pro nozzle dimensions and are thin enough at the base to sit inside the charging case when the earbuds are docked. The inner opening grips the earbud nozzle to stay secure during use.

• Designed specifically for Buds 3 & 4 Pro compatibility.
• Form factor allows earbuds to return to case without obstruction.
• Secure nozzle fit reduces accidental detachment while wearing.

How long do SONICFOAM tips last and how do I care for them?

Memory foam naturally degrades with repeated compression and ear oils; a single pair typically performs well for up to four weeks depending on usage and hygiene. Rotate sizes from the included tester set to find the best fit, and keep the tips clean to extend usable life.

• Estimated lifespan: about 4 weeks per pair under regular use.
• Gently wipe with a damp cloth and mild soap; avoid soaking.
• Replace when foam no longer rebounds or becomes discolored.

Which size should I try first and what are the dimensions?

The pack includes small, medium, and large to help you find the comfortable seal. Dimensions are approximate — small 11mm, medium 12mm, large 13mm width; height is 8.5mm for all sizes — so start with medium and swap if the seal or comfort isn’t right.

• Tester approach: try M first, then S or L depending on comfort and seal.
• Small = 11mm wide, Medium = 12mm wide, Large = 13mm wide (approx.).
• Height 8.5mm for all sizes; consistent insertion depth and fit.

Who is this for? SONICFOAM tips are ideal for Buds 3 & 4 Pro owners who want a quick, inexpensive way to improve comfort, noise isolation, and perceived bass without modifying the earbuds. They work well for commuters, gym-goers, frequent travelers, and anyone whose original silicone tips no longer seal properly. The 3-pair tester set helps you find the best fit and keep spare tips on hand for travel or replacement.
