Their revolutionary filter system drops the volume evenly by around 16- 20db at all frequencies, preserving sound quality. Sound isn’t muffled, but heard at a safe volume. That’s why they’re labelled ‘High Fidelity Hearing Protection’.
Each ER20 pack comes with a handy soft case, neck cord, user guide and instructions.
Delivery: No charge
