The MusicSafe Classic offers professional hearing protection from Alpine, a leader in innovative solutions for hearing protection. Alpine MusicSafe Classic contains two different and interchangeable sets of music filters with outstanding sound characteristics, perfect for medium and high attenuation rates. These special music filters guarantee optimal protection without loss of clarity, while at the same time ensuring a pleasurable listening experience. Alpine MusicSafe Classic earplugs are produced from a very soft, flexible, and durable thermoplastic material that adapts to the unique shape of your auditory duct, and are thus very comfortable to wear. MusicSafe Classic earplugs with special music filters are an open system, making sure that you don't feel separated from the music you are listening to or making.

The building blocks of Alpine products are scientific research, innovation, and know-how. Alpine products are either TNO-tested or CE-standardized, and developed in their own ISOI 9002-certified laboratory.
