MusicSafe hearing protection is made from durable and flexible AlpineThermoShape™ material. Thanks to the warmth of the ear, the earplug moulds to the ear canal within minutes, significantly improving wearing comfort. The thermoplastic material is hypoallergenic, preventing itching in or around the ear. Every pack contains a luxury travel pouch to store and transport the earplugs, two sets of exchangeable filters, and an Alpine insertion aid.
