Sometimes, all you need is passive hearing protectors. However, if you need to use hearing protection for long periods of time, features such as Bluetooth and AM/FM radio will make your working days a great deal more comfortable, efficient and fun.
Some environments place greater demands on your protection. If it is important to hear warning signals or be able to communicate with others in noisy environments, we highly recommend choosing an electronic hearing protector with the active listening feature, and, depending on your needs, two-way communication. Level dependent active listening protectors allow situational awareness while protectning against impulsive or intermittent hazardous noise. A noise cancelling speech microphone is also very useful in these circumstances.
