Alpine SleepSoft Custom 4D earplugs provide maximum reduction of environmental noise and snoring. These earplugs are fully custom-made, and thanks to digital production technology, the fit of the Alpine SleepSoft Custom 4D is extremely precise. The earplugs get their name from this ‘4D technology’. Not only is the exterior of the earplug custom-made, but the internal sound channel can also be shaped very accurately thanks to the computer scan. The super-soft material ensures optimal comfort, allowing the earplugs to stay comfortably in place for hours, even when sleeping on your side. Additionally, they are easy to insert and just as easy to remove.

In short: 100% custom and 100% convenience!
