Foam Ear Plugs Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Mack's is the best-performing foam ear plugs brand in July 2026, moving 67,000 units across 5 ASINs for 57.3% of Top 10 volume. Flents follows with 20,000 units (17.1%), ahead of Peace&Quiet on 10,000 units (8.5%).

With 6 brands splitting the Top 10 and 82.9% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $3.57 to $11.99, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B0CHJ79LSQ booked 7K units at $8.99, with ▲ 250.0% MoM change. On the growth side, B004CZYJLA leads positive momentum with ▲ 150.0% MoM growth on 5K units, with B001FPCUHA close behind at ▲ 100.0% MoM on 20K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
