Dekoni

Dekoni 3mm Memory Foam Isolation Tips for Gemini Earphone, Large, 3 Pack, Black

SKU CH-7SBM-4B40R

3 mm memory foam tips for Gemini earphones, large size, three-pack, improving comfort, isolation and sound quality

  • Premium memory foam molds to the ear canal for all-day comfort
  • 3 mm slow-rebound foam creates a tight seal that blocks external noise
  • Tighter acoustic seal delivers richer bass, clearer mids and detailed highs
  • High-grade foam resists compression for long-term shape retention
  • Washable with cold water and mild detergent to stay fresh and hygienic

Product identity

These are 3 mm memory foam isolation tips designed specifically for the Gemini earphone. They come as a pack of three large black tips intended for listeners who want a tighter seal and longer comfort during extended sessions.

Fit verification

Before ordering, confirm that your earphones are the Gemini model and that the large size matches the dimensions you usually wear. The tips are made for a single product line and will not fit other earphone designs or nozzle sizes.

Sustained use behaviour

The slow-rebound foam maintains its shape and seal over long listening periods, resisting the compression set that can loosen lesser tips. They are washable with cold water and mild detergent, so hygiene and consistent isolation remain stable through repeated daily wear.

Questions about this item

Does the pack contain anything besides the three large foam tips?

The package includes three large 3 mm memory-foam isolation tips and nothing else; no carrying case, cleaning tool or additional sizes are supplied.

How do I know the large size will fit my ears?

The tips are sized large for the Gemini earphone nozzle; if the standard tips that came with your Gemini feel loose or fall out, the large size usually provides a tighter seal.

What does the 3 mm thickness change compared with the stock tips?

The 3 mm memory-foam wall creates a deeper seal in the ear canal, increasing passive noise isolation and boosting low-frequency response while the slow-rebound foam reduces pressure during long sessions.
