Dabei handelt es sich um LED-Ring, welcher zwischen Stoffabdeckung der Treiber und Ohrpolster-Halterung angebracht ist. Overall, these are well executed, beautiful headphones, but they are not exceptional sound reproduction devices. 5mm cord handy. Now I dont have to worry about losing this teeny weeny headset! It so far seems to work well. Believing that it might of been my replacement wires (headphone to adapter) I prepped to order another one but forgot I had purchased another headphone adapter that for some reason has issues playing sound thru my ipod but no issues when connected to my PC. I love it-Confortable? Yes! Elegant for flats and much needed for my height. When I plug my EarPods in, they sound way better than these at higher volumes. They also passed with flying colors on our water adventures.
