棉花糖耳塞套

The medium size creates a perfect seal for my earphones, blocking out noise without discomfort. Having three pairs in the pack gives me peace of mind that I won't run out

Swapped these onto my earphones and the seal is noticeably better than the silicone ones I had before. Three pairs per set means I've got spares for when the foam eventually wears out.

I've been using foam tips for years and these compress down much easier than others I've tried, so getting a good seal takes seconds. The three pairs per set is generous too, since foam eventually wears out.
