QuieTunes 660 muffs from Elvex provide AM/FM reception so that workers can enjoy listening to music or talk radio while wearing hearing protection. The electronics in the contemporary looking product are separated from the hearing protection cavities so moisture and sweat don’t affect the lifespan of the electronics. Using two AA batteries, the muffs have an NRR of 22 dB. Elvex Corp., Bethel, CT.
