Frequently Asked Questions

Since the Tufftalk M comes in 2 versions, over-the-head and hard hat, it can be used in a wide variety of industries where people want to communicate with each other while wearing ear protection. For the over-the-head version those industries can range from drone pilots on a camera crew who need to communicate in order to capture the footage that they need for their production team to instructors on a race track who need to talk to a student and teach them what they need to know and more. For the hard hat version those industries can range from factory workers who need to talk to each other in loud and noisy environments to arborists who need crew members on the ground be able to talk other crew members cutting branches in trees and more.

The Tufftalk M is compatible with a wide variety of hard hats on the market. Included in the package for the Tufftalk M are two adapters (Type A and Type B) so that the ear muffs can fit into most helmets. If the Type A Hard Hat Adapter that comes attached to the Tufftalk M do not fit in the left and right slots on the hard hat then replace them with the Type B Hard Hat Adapters.

The Tufftalk M features Sena's Mesh 2.0 intercom technology which makes communicating in groups easier than the Tufftalk or Tufftalk Lite. With Mesh 2.0, the Tufftalk M does not need to be paired to other members of the group like with the Bluetooth Intercom feature on the Tufftalk and Tufftalk Lite. In addition, the Tufftalk and Tufftalk Lite only allow up to 4 people to communicate with each other while the Tufftalk M allows a virtually limitless amount of people to talk to each other within 1.1 km (0.7 miles) in open terrain. In open terrain, the Mesh can be extended up to 4.4 km (2.8 miles) between a minimum of 6 users.

To power on the headset, press and hold the Center Button and the (+) Button for 1 second. To power off the headset, tap the Center Button and the (+) Button.
