when the user tilts his head, the headphones will automatically level the sound stage using a gyroscope and various algorithms.\u00a0This will work both when watching movies and listening to music tracks, although not all users are enthusiastic about this solution.<\/p>\n<div id=\"attachment_148953\" style=\"width: 1210px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2022\/09\/ANKER-INTRODUCED-UNUSUAL-HEADPHONES.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-148953\" class=\"size-full wp-image-148953\" src=\"https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2022\/09\/ANKER-INTRODUCED-UNUSUAL-HEADPHONES.jpg\" alt=\"ANKER INTRODUCED UNUSUAL HEADPHONES\" width=\"1200\" height=\"760\" srcset=\"https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2022\/09\/ANKER-INTRODUCED-UNUSUAL-HEADPHONES.jpg 1200w, https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2022\/09\/ANKER-INTRODUCED-UNUSUAL-HEADPHONES-600x380.jpg 600w, https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2022\/09\/ANKER-INTRODUCED-UNUSUAL-HEADPHONES-800x507.jpg 800w, https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2022\/09\/ANKER-INTRODUCED-UNUSUAL-HEADPHONES-1080x684.jpg 1080w, https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2022\/09\/ANKER-INTRODUCED-UNUSUAL-HEADPHONES-770x488.jpg 770w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><\/a><p id=\"caption-attachment-148953\" class=\"wp-caption-text\">ANKER INTRODUCED UNUSUAL HEADPHONES<\/p><\/div>\n<p>In addition, these headphones boast a unique feature that competitors in the market do not have &#8211;
