This is the Beyer Dynamic DTX 80 Ambience Noise Blocking In-Ear Headphones. The DTX 80 is a sophisticated version of the basic earphone. A matt gleaming ring from glass blasted aluminium tops the sporty appearance. When not in use, the headset can be stored, as all earphones in the DTX series, in a stylish softcase provided, which fits nicely even in close-fitting sports gear. The sound impresses with its stirring live character and the extensive elimination of static.
