Pros: Sounds big, compared to absolutely worse models.
Cons: 30-60hz deep bass is weak. Treble is extremely harsh, comes amplified without any improvement in clarity.
i just can't believe how people like everything they buy. this thing incorporates one of the worse treble productions i've seen to date. do your ears a favor and keep out from this.
after tried some models from this company, i instantly get it. this company just shows you an attractive casing and puts crippled drivers in it to make your money go away. there's a lot better products, don't be fooled by the image.
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's 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.
