Concept's CDC-IR23 headphones include interchangeable colored ear cup covers, so everybody can pick their own look. Your crew can choose between two sources and control the volume for your mobile video system's music and movies directly from the 'phones. These headphones work wirelessly with any infrared (IR) transmitter, like those found in many mobile monitors we carry. Cups designed for comfort The headphones feature an auto turn-off that saves battery life (batteries included). The smaller on-ear cups are designed to sit comfortably on younger listeners. These cups also rotate, so they fold flat for easy storage when not in use. Concept includes a detachable 4-foot stereo mini cable, so you can plug directly into a laptop, smartphone, or a portable music player when a wired connection is needed. Note: These headphones are for use in motor vehicles only — they are not designed for home use. We also carry a selection of wireless headphones for home and portable systems.
