Plantronics’ Voyager 104 hands-free Bluetooth headset features rugged components that have been stress-tested to withstand tough conditions such as trucking environments. The headset has a long, flexible microphone boom with windscreen and DSP noise-canceling technology that helps cut background noise, while a close-fitting memory-foam earcup helps provide improved listening in noisy conditions while facilitating all-day comfort. On-ear controls for calls and music are designed for easy access, even with work gloves. The headset is engineered to provide up to 24 hours of battery life on a single charge and 40 days of standby time and is engineered to remain connected up to 60 feet away; two devices can be connected at once. The moisture-protected design and P2i nano-coating help protect against the corrosive properties of sweat and the elements.
