In-ear protection is unusual in that the user controls most of the performance. The published figure for the earbud assumes a complete acoustic seal in the canal; get the size wrong and the seal is partial, and a partial seal leaks noise straight past everything the electronics are doing.
Earmor call these self-developed foam eartips, designed to fit snugly in the ear canal for deep noise reduction. High-density slow-rebound foam is the material — roll it down, insert, and hold while it expands against the canal wall. That expansion is what makes the seal, which is why foam generally outperforms a silicone flange for isolation.
They are compliant with CE, RoHS and EN 352. What Earmor do not publish is an attenuation figure for the tips themselves, and neither does anyone else — so there is no NRR on this page. The rating belongs to the earbud system, not the tip.
Fitment is the M20T Pro, the M200T and the P20/P21. Note that is the Pro, not the plain M20 or M20T.

Frequently asked questions
Is there an NRR for these? No, and anyone quoting one is quoting something else. We published an approximate figure ourselves at first and then traced it — it belongs to the M33 earmuff in Earmor's own catalogue, not to the S30. The rating that matters is the earbud's.
Are they silicone? No, foam. Earmor's catalogue heading is explicit about it, and two independent retailers agree. Silicone flange tips are a different product.
Which size should I order? If the tips that came with your buds fall out, go smaller and firmer rather than larger. If they ache after an hour, go smaller. Comfort and seal usually arrive together, and mixing sizes between ears is normal.
Will they fit my M20 or M20T? Earmor name the M20T Pro, M200T, P20 and P21. The plain M20 and M20T are not on that list, so check before ordering.
