We have engineered ProGuard Music to cater for their needs, each earplug is tailored to the individual client, and it will fit like a glove into every nook and cranny of your complex ear anatomy. The custom-fit earplug will fit deep into the ear canal and sit comfortably there for long periods of time without it becoming uncomfortable or feeling obtrusive, manufactured from tactile soft medical grade silicon they will require very little maintenance over their lifetime just the occasional wash in warm soapy water and a quick dry before inserting them into the ear is all that is required. The magic part of the these music earplugs is the acoustic filters we use, calibrated at various SNR levels they will allow the sound to pass through with all the same complexity as how it was originally played but at a lower volume to save your delicate ears from the rigours of loud music. Each ProGuard earplug comes to you with a choice of two pairs of filter and a filter insertion tool. All ProGuard filters are interchangeable to suit your listening environment; the lower level (Blue) designed to give adequate protection for general gigging and concert goers gives an SNR protection level of 18dB. The higher attenuation version (Green) where regular listeners are in extremely high volume environments typically DJs, Drummers and musicians in very loud bands, this filter will give an SNR rating of 23dB. It might not seem that 5dB will make that much difference but you should be aware that a 3dB difference is effectively doubling the sound so small differences in numbers can have quite an effect. Filters: Blue = SNR 18dB; Green = 23dB All our acoustic filters are replaceable and should you require a new filter or a different value of noise reduction please contact us, we are only to happy to help.
