The Allen ULTRX Shift Adjustable Earplugs (Allen part no. 4103) let shooters fine-tune the fit of their in-ear hearing protection instead of relying on a single fixed size. That adjustability helps achieve a more consistent seal across different ear shapes, which matters for how effectively any in-ear plug actually blocks noise. As part of Allen’s ULTRX lineup, the Shift plugs deliver passive protection through their in-the-ear design, without any electronics or batteries involved. They’re a practical option for shooters who’ve struggled to get a proper seal with fixed-size foam or silicone plugs in the past. Allen built the Shift model specifically to address that common fit problem within its broader hearing protection range.

Key Specifications

• Uses an adjustable in-the-ear design for a more personalized seal.
