Description
Anyone who splits their time between the range, the shop, and the occasional loud crowd knows that one fixed level of hearing protection doesn't always cut it. The Allen ULTRX Shift solves that with a button on each plug that lets you jump between 12 dB and 25 dB of noise reduction on the fly. Open them up when you want to hear range commands or a conversation, then click them shut when the shooting starts. It's a simple mechanical design with no batteries or electronics to worry about.
How the Shift Ear Plugs Change on the Fly
The adjustable protection is the whole point here. A quick push of the button swaps you between the lower 12 dB setting and the higher 25 dB rating, so you're not stuck pulling plugs in and out every time the noise level changes. That flexibility makes them handy well beyond the firing line, whether you're running a saw in the garage or standing near the speakers at a show.
Comfort Built Into the ULTRX Shift Fit
Both plugs use soft silicone inserts paired with a stabilizing wing that tucks into the ear to hold everything in place. The in-ear format is on the smaller side, which helps them seat comfortably in a range of ear canal sizes without that fatiguing pressure that makes cheaper plugs a chore to wear for a full session. Lightweight construction means you can leave them in for hours without much thought.
The gray and neon yellow color scheme isn't just for looks either, since the bright accents make them easy to spot if you set them down on a bench or drop one in the grass. They come with a compact carry pouch, so you can keep the pair together and clean between uses and toss them in a range bag, glovebox, or pocket. For a no-fuss, do-it-all set of plugs, the ULTRX Shift covers a lot of ground.

Frequently Asked Questions
How do you adjust the protection level on the ULTRX Shift ear plugs?
Each plug has a push-button that toggles between two settings. The open position gives you a 12 dB noise reduction rating so you can stay aware of your surroundings, and pressing it shut bumps you up to 25 dB for louder environments. No tools or batteries needed.
Are these electronic ear plugs?
No, the ULTRX Shift is a passive design, meaning the protection comes from the physical seal and the mechanical filter rather than amplification or electronics. That keeps them simple and reliable with nothing to charge. If you want a set that amplifies quiet sounds, Allen makes electronic options in the ULTRX line instead.
Will the Allen ULTRX Shift plugs fit smaller ears?
They use a small in-ear format with soft silicone inserts and a stabilizing wing designed to seat in a range of ear canal sizes. Most folks find the fit comfortable for extended wear, though ear shape varies from person to person. The wing helps keep them planted so they don't back out during movement.
What are these ear plugs good for besides shooting?
The adjustable setup makes them useful anywhere noise levels change. Plenty of people use them for shop and power tool work, mowing, concerts, and travel in addition to range time. Being able to click between hearing conversations and blocking loud noise is what makes them versatile.
