Wireless connection BSHSBE200 series, black headset with 80mAh battery. - Model: BSHSBE200 Series - Battery Capacity: 80mAh - Color: Blue - Manufacturer: Buffalo Inc. - Connection Method: Wireless I purchased this for the purpose of calling a friend while fishing, but I was told it picked up too much of the sound of the waves, so I am selling it to replace it. I have only used it once, so I think it is in good condition. The accessories are all that are shown in the fourth photo. Thank you for viewing.
