What COTOE Claims About This Headset
COTOE advertises 72 hours of total talk time when the earpiece is paired with its included 500mAh charging case, on top of a stated 120 hours of standby time.
The headset runs Bluetooth V5.3 and is built around a single in-ear mono design with a rotating boom mic, not a stereo headphone.
A physical mute button on the unit is meant to let the wearer silence the mic mid-call without fumbling for a phone app.
COTOE describes the mic as noise-cancelling, intended for use in vehicle cabins and open offices, though no independent measurement of how much noise it actually rejects is available.
The earpiece geometry is adjustable: the in-ear tip rotates about 45 degrees, the ear hook 360 degrees, and the mic arm 180 degrees, according to the listing and instruction manual.
The charging case has an LED digital display showing case and earpiece battery levels, a feature more common on wireless earbuds than on single-ear business headsets.
72 hours of talk time from a 500mAh case implies very low continuous power draw per charge cycle; we have no way to verify this figure independently, and it should be read as a manufacturer claim, not a tested result.
