  • Triple-flanged-stem provides a Noise Reduction Rating (NRR) of 24 dB
  • Safe sound levels are allowed to pass through into the ear canal, while potentially harmful noises (above 85 dB) are reduced via proprietary noise-reducing filter
  • EP4s include attached filter caps that can be inserted for additional protection, blocking out lower-level noise, like that heard on an airplane, where hearing ambient sounds or conversations isn't critical
  • Made from a soft, durable, hypoallergenic polymer that provides all-day comfort and extends product life (up to 6+ months, depending on usage and care)
