Mack's Pillow Soft Silicone Earplugs
Best for: Side sleepers and sensitive or small ear canals
The side-sleeper and sensitive-ear pick — moldable silicone that caps the ear opening flush instead of jamming into the canal, gentle enough for ears that hate foam.
Mack's Pillow Soft is the original moldable silicone plug, and it solves a specific problem foam can't. Instead of inserting into the canal, you warm a ball of silicone and press it over the ear opening so it caps flush — nothing protrudes to be pushed in by a pillow, and nothing invades a sensitive or narrow canal. That makes it the go-to for side sleepers, small ears, kids, and swimmers. It blocks less than foam (around 22dB) and it's fiddlier — you mold each plug by hand and it can slip if your ears are oily or your hair catches it — and Mack's says each plug can be reused until it is dirty or no longer sticky, up to 5 uses. But for gentle, flush, side-sleeper-friendly quiet, nothing else feels like it.

How our prices work
We show the price at our recommended retailer as at our last check of that offer (2026-11-01) and, when Amazon reports one, its list price for comparison.

Frequently asked questions
Mack's Pillow Soft silicone vs Ohropax wax?
Both mold over the ear opening rather than inserting. Silicone is cleaner and less sticky; Ohropax's wax molds softer and warmer and has a devoted following. Cleaner and firmer: Mack's silicone. Softer, warmer custom seal: Ohropax.
Mack's silicone vs Mack's foam?
The silicone caps the ear opening flush and is gentler on the canal — better for side sleepers and sensitive ears; the foam inserts deeper and blocks more raw noise (33dB vs 22dB). Gentle and flush: silicone. Maximum quiet: foam.
Pillow Soft vs Loop Quiet for side sleepers?
Both are low-profile side-sleeper favourites. Loop Quiet is reusable and blocks a bit more; Pillow Soft is gentler and caps the opening without any canal insertion — the pick for the most sensitive ears. Reuse and more blocking: Loop. Gentlest flush fit: Pillow Soft.
Can you reuse Mack's Pillow Soft plugs?
Yes, within limits. Mack's says the plugs can be reused until they are dirty or no longer sticky, up to 5 uses. The brand says they can't be cleaned, and that clean, dry hands and ears help them last longer.
