With Alpine WorkSafe Custom 4D earplugs you are protected against loud and harmful noises while doing odd jobs, while the conversations with your job partner remain perfectly intelligible.
100% custom, 100% convenience
The custom earplugs are specially developed for do-it-yourselfers and professionals and are thus shaped for use during DIY jobs. Thanks to the digital production technique, the fit is extremely accurate. The otoplastics owe their name to this ‘4D technology’. Not only the outside of the earplug is made to measure, the sound channel on the inside can also be designed very precisely thanks to the computer scan. The soft material improves the wearing comfort of the earplugs while retaining the Alpine quality. 100% customized and 100% convenience.
Includes practical carrying cord
Every Alpine WorkSafe Custom 4D comes with a lanyard with which you can wear the earplugs around your neck when you take them out of your ears. Use of the lanyard does not affect the operation of the filter, the damping remains the same.
Unique in Europe: mini-grip removal aid
Removing earplugs from the ears is not always easy. Alpine is therefore the first in Europe to offer a unique removal aid, called the mini-grip. Thanks to a small and inconspicuous lip, you have more grip and you can easily remove the DIY earplug from your ear. The mini-grip is made of the same flexible material as the earplug, so that the hearing protectors stay in place comfortably while doing odd jobs. The earplugs also have a lanyard for quick and easy work.
Own name and unique number on earplugs
Earplugs are easily lost or confused with someone else’s. Each of our otoplastics has a unique number and your own first name. This makes it easy and quick to trace the owner of the earplug.
Reorder with saved scan
In addition to the fact that Alpine WorkSafe Custom 4D earplugs have the perfect fit, the digital production process provides another advantage. Your scans and data are stored by us, so you can always reorder earplugs. Handy in case of loss or when you want to purchase another version, for example earplugs for sleeping or partying.
Free filter change and leak test
Custom earplugs can be measured at our office in Soesterberg and only takes 15 minutes. When measuring Alpine WorkSafe Custom 4D, there is a choice of no less than three filters (high, medium & low) which provide different attenuation. Moreover, you can have the filters changed for free. You can also come by for a free leak test at any time to check whether the earplugs still close properly.
With this version there is a choice of three different filters, namely the green (F7), red (F8) and white (F10) filter. The three filters have been tested by the TNO according to the standards of EN 352-2. The table below shows the results of the mean sound values ( Mf ), the standard deviation ( Sf ) and APV84 in dB for test frequencies between 125-8000 Hz.
