The 3M WorkTunes Connect + AM/FM is an over-the-head electronic hearing protector with NRR 24 dB that combines Bluetooth audio streaming with a built-in AM/FM radio tuner. It runs on two AAA batteries and weighs approximately 0.57 lbs. Intended for jobsite and yard use where workers want the flexibility of local AM/FM radio stations alongside Bluetooth device connectivity. Suited for construction, landscaping, and workshop environments.
Can I take phone calls with the WorkTunes Connect + AM/FM?
Yes. The unit has a built-in microphone and supports hands-free Bluetooth calling. AM/FM radio pauses when a call comes in, and you can resume radio playback after the call ends.
Does the NRR rating still apply when music or radio is playing?
Yes. NRR 24 dB attenuation is provided by the physical ear cup seal and cushions, which function independently of the audio electronics. Playing audio does not reduce the noise reduction rating.
How is AM/FM reception on a noisy jobsite?
AM/FM reception depends on distance from local towers and jobsite obstructions. On outdoor sites FM reception is generally reliable. AM reception can be weaker around metal structures or equipment. The telescoping antenna (or wire antenna, model-dependent) improves signal.
Which audio source has priority — Bluetooth or AM/FM?
Bluetooth typically takes priority when a call or audio stream arrives. The unit will switch back to AM/FM radio after the Bluetooth audio ends, depending on firmware behavior. You can manually select source with the mode button.
Why does it use AAA batteries instead of a rechargeable battery?
AAA batteries are swappable in seconds without any downtime. For all-day jobsite use, carrying a spare set means no waiting for a recharge. This makes them practical for contractors who start early and work until dusk.
Can I wear this under a hard hat?
Yes, it is designed to be compatible with standard hard hats. Fit depends on specific helmet geometry. Standard Class E hard hats typically accommodate the ear cups without issue.
