This motorcycle helmet Bluetooth headset is designed for riders who want hands-free communication and audio streaming while on the road. It installs onto full-face or half helmets and pairs with a smartphone to handle calls, music, and GPS directions without requiring the rider to remove gloves or handle the phone. The built-in microphone picks up voice clearly at highway speeds, helping the rider stay connected while keeping both hands on the handlebars. The unit measures about 5.51 x 4.72 x 1.97 in / 14 x 12 x 5 cm and weighs about 0.31 lb / 142 g, staying compact on the helmet shell. One headset unit with mounting hardware is included in the package. To install, attach the clamp to the helmet edge and position the speaker and microphone inside. Pair with your phone through the Bluetooth settings on your device. Wipe the exterior with a dry cloth when dirty. Charge the battery fully before first use and store the headset in a dry place when not riding.
