Why crane crews look past Sensear

Sensear says its Smart Headsets let workers communicate face-to-face in noise levels up to 95 dB(A), and via two-way radio and Bluetooth on mobile phones up to 120 dB(A). ^[3] A crew can check the noise on its own site, the number of headsets it must charge and store, and how the crew already talks during a lift. Those points can help compare whether a headset system or a phone-based tool suits the job. A crew should compare Sensear's own noise ratings and headset counts against the conditions on its site before choosing. The price is also worth checking directly on Sensear's page before comparing it with the options below. Sensear does not publish a price on this page. Each option handles noise, headset count and crew size in its own way, so a reader can match the stated details to the crew's own needs.
