The Allen ULTRX Shield Passive Earmuffs in Plum (Allen part no. 4105) round out the color options in Allen’s Shield earmuff line, part of the broader ULTRX hearing and eye protection range. The plum colorway gives shooters who prefer a distinctive look an alternative to Allen’s more neutral grey and navy Shield options, without any change to the earmuff’s fit or protective function. These earmuffs use an over-the-head design with passive noise reduction, relying on a cushioned, snug seal around the ear rather than batteries or built-in electronics. Allen built the Shield line as a reliable, no-frills entry point into its ULTRX hearing protection lineup. It’s a solid option for range days, hunting trips, or any setting where consistent passive hearing protection matters.
