Point Source Audio reinvents the Intercom Headset for Hard Hats
Point Source Audioβs patented CM-i family of lightweight in-ear intercom headsets has received a design upgrade. The new designβbrought to market earlier than initially planned in light of the current health crisisβadds factors such as detachable earbuds for improved hygiene and maintenance.
The increased sound isolation offered by an in-ear intercom solution has been embraced by industrial crews working in construction, medical and energy industries all over the world. This has given users the ability to better protect their hearing with lower overall volume as external noise is significantly reduced.
First launched in 2016, the patented modular CM-i headsets with in-earphones provide noise-isolation typical from big earmuffs, but without the heavy weight. The CM-i3 and CM-i5βs featherweight assembly weigh just between 1 to 2oz. so they can be worn comfortably all day under hard hats, helmets, and even hazmat suits.
The comfort and effectiveness of in-ear headsets are a no-brainer, but no one is comfortable sharing in-earphones no matter how well they may be cleaned. The new detachable in-ear design addresses hygienic concerns with earphones that quickly detach from the cable so they can be assigned to the user and replaced for new users.
The removable earphones are a common feature to both the CM-i3 and CM-i5 intercom headsets which helps companies address the challenging health management of cleaning and maintaining required safety equipment worn by its staff. The in-earphones are a highly personal item, and typical with small electronic parts may be difficult to sanitize properly. The personal assignment of the detachable in-earphones ensures that users take responsibility for their in-ear buds and there is never any sharing of the in-ears themselves.
βThe current global situation has brought hygiene to the front of everybodyβs mindset, but in fact, these challenges have always been looming,β says James Lamb, president of Point Source Audio. βThis design change can help ease the administration process of dispensing personal gear to work crews, especially in regard to reducing the health risks if sharing equipment.β

Designed for clarity and all-day wearing comfort, the CM-i line is the worldβs only series of modular in-ear intercom headsets offering a revolutionary combination of in-ear performance, increased isolation, lightweight comfort, and earphone modularity. The robust feature set makes these headsets ideal for teams who rely vitally on the ability to hear clearlyβand react quickly.
βCustomers tell us again and again that they will never go back to their old-style headsets after using a Point Source headset,β says Lamb. βFor anyone who must work in loud environments, or have health concerns about sharing headsets or bulky headsets that weigh too much, our intercom headsets will give them relief from all these problems. Add in the ability to switch to your own in-earphones for hygiene and peace of mind, and the CM-i family delivers an unbeatable proposition.β
