Kids, these headphones have been created with you in mind using the latest KitSound technology to give you proper sound quality and mad street styles. LOL! They are fully adjustable so no matter how big or small your head is, you will be able to get a perfect fit. The outer shell of the earcup is insulated to block out background noise so you can hear your music without having to crank it up to nosebleed loud. The styling is based on the designs being used by top DJ"s and you will stand out from the crowd when you wear these. They have big comfy padding and will ride snugly on your head. They are super lightweight and tough at the same time. Enjoy.Neodymium magnet 40mm driverFrequency response 20Hz - 20kHzSensitivity 85dB @ 1mwCable length 1.6m(Research has shown that listening to loud music over a long period of time can potentially lead to noise induced hearing loss (NIHL). These headphones have been engineered so that the level of sound being delivered to the ears does not exceed an average of 85dB in the long term. This is the figure recommended by healthcare professionals.)Please click here to follow us on FacebookPlease click here to follow us on Twitter
