01 · The mic matters more than the speaker
You are not buying sound quality, you are buying being understood. A cab at highway speed is loud, and a phone speaker sends all of it to dispatch. The noise-cancelling boom is the entire product.
02 · Mono or stereo?
Mono leaves an ear open for the road, the CB and the yard. Stereo is better for audiobooks and podcasts. ⚠️ Several states restrict covering both ears while driving — check your state before you buy the stereo.
03 · 91% vs 96% vs 98%
The jump from 91% to 96% is the one you will actually hear. 96% to 98% matters if you take calls outside the truck — yards, docks, next to a running reefer. Inside a modern cab, 96% is plenty.
04 · Battery is a shift-length question
Anything here covers a normal shift. If you team drive or leave it connected all day, size up — a headset that dies at hour eleven is a headset you stop wearing.
