Alpine SleepSoft Custom 4D earplugs provide maximum attenuation of ambient noise and snoring. These earplugs are custom-made, and thanks to digital production technology, the fit of the Alpine SleepSoft Custom 4D is extremely precise. The earplugs owe their name to this “4D technology.” Not only is the outer part of the earplug custom-shaped, but the internal sound channel can also be formed with high precision using a computer scan. The super-soft material ensures optimal comfort, so the earplugs remain comfortable to wear for hours, even when sleeping on your side. They are also easy to insert and just as easy to remove.

In short: 100% custom-made and 100% convenience!
