Allen ULTRX Sound Blocker Features The Allen ULTRX Sound Blocker earmuff delivers a 23 decibel noise reduction rating giving reliable protection against the noise levels produced on a shooting range or around loud machinery. Its over-the-head design uses a soft cushioned headband alongside plush ear cups to keep the muffs comfortable through long sessions rather than becoming a distraction after the first hour. That comfort matters as much as the attenuation rating itself since a muff that pinches or chafes is one a shooter stops wearing correctly. The earmuffs meet ANSI S3.19 safety standards giving users confidence the stated protection rating reflects a genuine tested performance level. A foldable design lets the Sound Blocker collapse down into a compact shape for storage fitting easily into a range bag glove box or tool kit without taking up the space a rigid muff would. That portability makes the earmuffs a practical option to keep on hand for an impromptu range trip or a loud job site task. As a passive muff with no batteries or electronics to maintain the Sound Blocker is ready to use the moment it comes out of the bag. For shooters and workers who want simple comfortable and compliant hearing protection the Allen ULTRX Sound Blocker is available for sale at GrabAGun.
