Prevent students from turning their headphones up to dangerous volume levels with Califone Sound Alert Stereo Headphones. A red LED light on the earcup shines when the volume is louder than the American Speech-Language-Hearing Association recommended 85dB level, so the teacher knows immediately when to take action. Cushioned leatherette earcups fit around the ears, blocking out distracting ambient noise and reducing the need for higher volumes. Califone Sound Alert Stereo Headphones come backed by a two-year warranty. Use for Common Core testing, including the PARCC, SBAC & NAEP.
