As the volume on the stage becomes louder on smaller and smaller stages, you need to protect your ears from damage that could come from the loud amplifiers and speakers on the stage, which are sometimes just a few feet from your head. These in-ear hearing protectors offer up to 19 dB protection against loud and dangerous frequencies that can damage your hearing. This pack contains two sets of rubber earbuds, one set of filters along with a carrying case and a lanyard to keep the earmuffs close at all times if you need to remove them from your ears for any reason. Good hearing protection is the basis for every concert musician or if you are a concert goer, so that you do not damage your ears and can enjoy and perform music for many years to come.Battery Operation: NoOriginal Colour by Producer: BlackColour: BlackMade in: ChinaMaterial: SiliconeActive noise cancellation: NoPackage Contents: EarplugsPackage Contents: Plastic CasePackage Contents: ManualType: In-Ear
