The Cisno BH-M20 Bluetooth headset is designed for truckers as evidenced by its DPS noise cancellation feature, its claim of blocking four times external noises, and 12-hour talk time, but its 250-hour stand-by time and 30-foot Bluetooth range are both pretty standard.

Also called Cisno Truckers BH-M20.
