Pro Ears Gold Series
Only Ridgeline's 'DLSC' technology protects hearing while at the same time allowing the wearer to hear lower volume sounds such as normal conversation. 'DLSC' works by instantly 'compressing' all noises over the 70 dB threshold by 50% to a safe level while amplifying all sounds below that to 70 dB. The result is the wearer will hear everything, including conversation, while simultaneously being protected from dangerous, high volume sounds.
