Wireless Bluetooth Stereo Headset. Wireless headset with Bluetooth connection. Lightweight and balanced, featuring a soft padded, adjustable headband and ear cups. Boom microphone (removable and rotatable) - additional built-in microphone for use without the boom mic. Convenient touch audio controls on the ear and mute switch on the headband. Rechargeable 410 mAh lithium-polymer battery with on-ear battery checker - over 16 hours of talk or play time. Wireless pairing with up to 2 devices via Bluetooth 5.0 - 3.5mm audio jack for wired audio connection (Aux cable included). Optimal clarity thanks to noise-canceling microphone. Focusing entirely on your conversation partner in a busy and correspondingly loud environment is one side of the challenge - the other is to communicate effortlessly. This headset is equipped with a noise-canceling microphone to assist you: background noises are filtered and minimized, ensuring that your voice comes through clearly on the other end. This not only makes it easier for your conversation partner to understand you, but also conveys a sense of a calm and focused work environment.
