Simply wow! We had the opportunity to test out one of the PRO quality earphones by KZ, the KZ ZST Pro Armature Dual Driver Earphone. The earbuds comes in a very stylish box, where the earbuds and cables are seperated. Oh yes, you can change the cables, those are detachable! You can use several types of them, depends of your needs.
Now back to the earbuds. Very impressive. These probably are the best you can get for around this pricepoint. They sound much better than earbuds that cost five times as much. Bass is enough but not too over whelming on the ZST model. More bass can be obtained but less treble with the ED12 since it only has one bigger dynamic driver instead of 2 on the ZST. The two drivers in each ear (1 dynamic for bass and 1 balanced armature for treble) makes wide ranging frequency from these accurately. The sound signature suits very well and I was mind blown when I first turned them on. The treble is clear and sharp but not too sharp. Bass is punchy and not dull like other earphones from beats.
