Why choose the 3M PELTOR CH-3 FLX2 Helmet Headset?
This headset brings hearing protection and communication to a new level of performance. It features newly designed speakers optimized for today's digital devices and a water-tight IP68 noise-cancelling microphone that guarantees your voice is heard clearly, even in the harshest conditions. The dual-mold slim cup design offers a modern look, while the bright yellow color significantly enhances worker visibility on site.
What industries is this headset best suited for?
The CH-3 FLX2 is built for demanding workplaces. It is highly recommended for professionals in construction, pulp and paper manufacturing, and airport applications. Wherever frequent contact with co-workers is required alongside heavy machinery or loud background noise, this headset delivers reliable, all-day performance.
How does it connect to my two-way radio?
This headset utilizes a highly flexible, detachable down lead connector system. To connect it to your specific two-way radio, you will need a compatible FLX2 lead (sold separately). For example, if your team uses Motorola devices, you can easily pair this headset with the FLX2 Cable for Motorola DP1400 or the FLX2 Cable for MOTOTRBO DP4000 Series.
Are there other wearing styles available?
Absolutely. If a helmet attachment doesn't fit your operational requirements, the CH-3 FLX2 series offers alternative wearing styles. You can explore the Neckband version for use with hats or face shields, or the standard Headband version for everyday use.
