Bilsom 303L, Howard Leight
Review
The Bilsom 303L earplugs are the larger version of the Bilsom 303S. They have exactly the same attenuation as the smaller Bilsom 303S. They are strong earplugs and provide good attenuation over all frequencies. The sound quality is comparably good for a foam earplugs due to the flat attenuation curve. Therefore, the Bilsom 303L earplugs are also a good choice for loud concerts or other places with loud music.Comparisons of this earplug with other earplugs are available here.
