[. . . ] Please take some time to read carefully through this product information before using the product. [. . . ] The very low levels of distortion present within the DT 770 M mean that listening levels are higher than is actually perceived and we would like to warn you of this so that you are able to enjoy these headphones for many years without damage to your ears. The DT 770 M has been designed for drummers and monitoring purposes (FOH), and is suitable for use on stage and in the studio. The transducers are fitted to adjustable yokes which should be positioned to fully enclose the ear. This provides the optimum ear/speaker position for accurate sound monitoring. The headphone volume can be optimal adjusted using the volume control on the singlesided cable. Professional users should note that it is recommended practice for headphones to be issued on an individual user basis to preclude any possible health risks. This symbol on the product, in the instructions or on the packaging means that your electrical and electronic equipment should be disposed at the end of its life separately from your household waste. For more information, please contact the local authority or your retailer where you purchased the product.
