grecab Bluetooth on-ear office headset designed for clear calls and long use. The boom microphone uses advanced environmental AI noise cancellation to block most background sound, and the accessible mute button on the mic lets you silence your voice instantly. Note: the headset is designed to disconnect while charging to protect the unit — do not charge if you need continuous use. Power & charging: built-in 600mAh battery delivers over 37 hours of working time and up to 230 hours standby after a full charge, which takes about 2 hours. A dedicated charging base/stand is included for convenient recharging. Please turn the headset off before placing it on the charger.

A USB Bluetooth dongle is included for computers without built-in Bluetooth. Important: the MFB (multi-function) button cannot answer or reject calls when the headset is used with a computer. Multi-device & range: the headset can connect to two Bluetooth devices simultaneously so you can switch quickly between a computer and a phone. Wireless range is up to 33 feet. Warning: do not connect one device via the USB dongle and the other via Bluetooth at the same time. Comfort & use: soft ear pads, an adjustable headband and a flexible mic stalk provide all-day comfort and optimal voice pickup. When not using the headset, unplug the USB dongle from your computer and plug it back in when you need the headset again.
