This is my first IEM and kz did an wonderful job making this piece of beauty, paired along with a dac it's even better, the lows are good, the mids and highs are even better, the stereo seperation and audio quality is much better than my previous tws. This tws even got a control switch, if you're an audiophile then this would make a difference you'll feel it, but to other people who uses casually not much of a difference they'll feel, the iem feels premium and the wire quality is good. Lastly thanks audio store for providing this at one of the lowest prices where on other platform this ain't even available, the packaging was excellent and even if the outer cardboard box got a bit deformed but inside the product box were perfect so 10/10 on packaging. The quality of headphones 8.5/10, the quality of the audiocular dac I ordered with this iem 8/10. Overall go for this iem at this price range this is a beast.
