Described as a groundbreaking collaboration between the legendary Italian designer Diesel and Monster Cables, the resulting Diesel VEKTR over-the-head headphones are visually unique and audibly superior. These Monster headphones have an angular design, which makes them stand out from the crowd. For sound reproduction, the Diesel VEKTR over-the-head headphones offer a frequency response from 20 Hz to 20 kHz +/- 3 dB, meaning the bass notes are pure and pack a punch, while the midrange and high-end frequencies are sharp and defined without sounding tinny, piercing, or shrill. Featuring a tri-fold design, these Monster headphones will collapse to small dimensions for carrying and storage, and a tangle-free cable means the user has to spend less time fiddling with the wires before connecting to a music source. These Monster headphones have a 1.4-m cable terminating in a standard 3.5-mm stereo jack plug for connection to virtually any portable music system or mobile phone.
