The Stereo Noise Blocking Earmuffs have a Noise Reduction Rating of 25 decibels. You can plug them into most MP3 players, smart phones, and other audio devices that have a 1/8" (3.5mm) headphone jack. A standard 1/8" patch cord comes with the headphones but if you need something more durable try our 3' mini 3.5mm stereo audio patch cable with right angle connector. The right angle connector helps absorb the pressure from the headphone jack of your device.
These earmuffs are comfortable and light weight. It is recommended that you replace the ear cushions and foam inserts at least once a year. Click here for more information on the available Hygiene Kit.
