"The POLONA03 headset is the perfect choice for phone calls, video conferencing and chatting online. The flexible microphone features noise cancelling technology that picks up your voice and blocks background noise, and delivers clear, high-fidelity sound. A 270-degree rotatable microphone easily adjusts to find the perfect angle for voice capture, and can be worn on the left or right ear according to personal preference. The headset also features a microphone mute button which can be activated with a single press.
This lightweight headset has soft ear pads and an adjustable headband for long-term comfort, while the powerful battery provides continual operation for up to 22 hours under normal use.
The headset comes equipped with a charging dock, which can decrease desktop clutter by acting as the perfect stand while not in use, simultaneously charging the device whilst inactive. The headset also offers direct charging via a cable.
The versatile and feature-rich Noise-cancelling Wireless Microphone Headset is a perfect option for busy call centers, general workplace environments or daily home use.
Note: The dock has no battery. Charging cable required. "
