One year warranty for school use - unlike headphones purchased at consumer electronics stores whose warranties would be voided if used in schools. |
Stereo headphones are specifically built for young students with safety as its first concern. Adjustable headband provides a comfortable fit for extended wear. Permanently attached cord with a reinforced strain" connection prevents it from detaching for lasting use. Right-angle plug resists accidental pullout. Noise-reducing earcup lowers ambient noise so the volume does not need to be played at high levels. Rugged, ABS plastic earcups resist breakage in high-use situations. Leatherette ear cushions are replaceable to maintain sanitary use. Volume control is set from the audio source for student safety. Headphones are perfect for classroom storytime, library and computer uses."Connectivity Technology: WiredCable Length: 5.50 ftSound Mode: StereoImpedance: 25 OhmMinimum Frequency Response: 20 HzMaximum Frequency Response: 20 kHzEarpiece Design: Over-the-headEarpiece Type: BinauralHost Interface: Mini-phoneColor: BlueForm Factor: CircumauralWeight (Approximate): 9.60 ozCountry of Origin: ChinaLimited Warranty: 1 Year
