EP4 Sonic Defenders Plus protect your hearing, without interfering with your ability to hear routine sounds and conversation. Safe sound levels are allowed to pass through while potentially harmful noises (above 80dB) are reduced via a proprietary design that incorporates the patented Hocks Noise Braker filter. When even more hearing protection is required—without the need to hear routine sounds or conversations—Sound Defenders’ attached stoppers can be inserted. The right/left color-coded Sonic Defenders are made from a soft, hypoallergenic polymer and ergonomically shaped, with a multi-flanged stem, providing a comfortable all-day fit. And their low-profile design means they can be worn while wearing a helmet or mask or while using a phone or headset.
