AS06 is the most interesting thing KZ did. This IEM is so cheap but sound quality is actually comparable to 200$+ sets. 3 ba drivers (bass-mid-high) Driver config was simple because no dinamic driver inside and amount of BA driver is only 3 so the tuning was soo succesful and easy. the result was unbeliveably good so much that they were not sure to continue to produce it because PRICE/PERFORMANCE wise the product is overly good for the market and rival IEMs. The poeple who bought this set was lucky. It only has 1 problem though, midbass is a little bit too much but it can be easly fixed with eq. Also the cable is too thin and its not easy to find 0.75mm b pin cables...
Massive soundstage, holographic audio feel, top notch stereo imaging, high clarity, good bass(little bit meh on subs), detailed mids, non fatiguing airy nice treble. Very coherent sound from lows to highs. Amazing sound quality...
Also very comfortable on ears. No sharp edges, smooth curves
