The listening first stereo headphone is specifically built for young students with safety as its first concern. Rugged ABS plastic ear cups withstand daily use with slotted ear cup baffles to prevent accidental damage from prying fingers or foreign objects. The volume control is set from the audio source (not on the headphone or cord) for student safety. Its incompatibility makes it ideal for use with iOS, Android and Windows tablets and smartphones for assessments, story-time, library, and computers.
