Ear Protection GHS 25 I US 577793 Small, light and convenient – the cordless Bluetooth® earplugs are your daily companion in the workshop or on the jobsite. They help to protect you from noise with an ANSI-rated noise reduction rating (NRR) of 25 dB while you work all while listening to your favorite tunes with excellent sound quality. They can even enable you to make phone calls via Bluetooth®. You don't have to do without the function of earplugs: loud ambient noise outside the safe sound level of 79 dB (corresponds to EU standard EN352) is blocked.
