Pros: Soundstage is vertically big, making it more bearable than some extremely small sounding earphones but that's all
Cons: 30-60hz deep bass is badly weak, Treble is harsh comes amplified without any improvement in clarity, Mids are low on depth
i just can't believe how people like everything they buy. refer to my xiaomi pistons review for some recommendings, you can buy much much much better products with lower price! (note that i'm not even saying for the same price)
please just stay away from this company. i also tried cks55x, this company does nothing but putting cheap drivers into a good casing to make your money go away. if you have too much money please send me instead, thanks!
note: don't worry i've used the original product. mine was bought from accessoryjack, it came with the box. i sold it to an audio-technica fan who used multiple ckm500 and other ath products from different sellers including cdjapan (and he verified it). i also tried the cks55x with another audio-technica fan who already got everything they offer.
