Honeywell's QM24+ earmuffs from their Howard Leight hearing protection range. The QM24+ have been created using super light materials. This provides an almost weightless design making them comfortable to wear for long periods of time. These earmuffs have an SNR rating of 25dB. The headband can be adjusted into various positions desired by the wearer; over the head, behind the head or under the chin. The adaptability of these earmuffs mean that they are great in environments where you maybe on your back or upside down, or maybe you are in a tight spot with little head room. Dielectric construction makes the QM24+ suitable for use in electrical environments.
