I had for some months the Koss headphones - SparkPlug - hifi stereo earphones which I was very happy, but unfortunately the cable parted soon enough. The foam system used on the Koss is significantly more effective than the rubber windscreen used here with foam, I heard neither the cable nor my jaw when I eat chewing gum, or people talking in the train ... or my LG LG-KF700 Bluetooth Black (KF700.ANLDBK) that sounded! That said, with the Koss impossible to lie on the side while listening to music (painful ear), whereas here no problem. (3 pairs of studding are included: SL XL) correct frequency response, with less low as Koss cited, since the closure of the ear is less advanced.
