Communication headsets and systems allow two people to communicate over a distance. They come in industrial and tactical forms. Industrial two-way communication headsets fit under a hardhat to protect a worker's hearing in high-noise environments. They have a noise-cancelling boom microphone, a push-to-talk adapter and soft ear cushions for extended wear. Tactical two-way communication headsets fit under ballistic helmets, suppress gunshot noises and allow wearers to hear ambient sounds. They have gel ear cushions for extended wear and noise-cancelling boom microphones that can be positioned based on shooting preference.
