Product information

Description

The Conceptronic POLONA04B headset is designed for phone calls, video conferencing and online chatting. It combines wired and wireless connectivity and delivers clear, high-fidelity audio through a noise-cancelling flexible microphone that isolates the speaker's voice from background noise. The microphone rotates 270 degrees for precise positioning and includes a one-press mute button. The lightweight supra-aural design, soft ear pads and adjustable headband provide extended comfort, while the built-in battery supports up to 44 hours of continuous use under normal conditions.

Advantages

The POLONA04B provides both wired and wireless connectivity for versatile use with different devices, a rotatable noise-cancelling microphone for improved voice clarity, and a one-touch mute function for quick control. Its lightweight construction and adjustable headband ensure comfortable wear during long calls, and the long battery life supports extended usage without frequent charging.

The second type is actually inserted directly into the ear canal and offers some external noise suppression.: Supraaural
