For the guy looking for a loud headset in the truck, once again, Blue Parrot Roadwarrior B250XT or the XT+
At the loudest, it's too loud. I can have conversations while booming down the highway at full throttle with the window down.
I've talked six other drivers at work into buying them.
Bought one for my best friend.
Bought one for my wife.
Bought one for my boss for his birthday.
