Received in good time, and they sound great!
Great quality finish , very comfortable to wear. Included cable is not that good so recommended to change it right away.With good cable(lower ohms) one thing that you'll pretty easy notice is bit tighter bass.Get the KZ Silver replacement cable if on budget. Mids are pretty recessed and some vocals on a rare song might sound bit distant, but because of the fact, you get no sibilance and no harshness even in songs that would have harshness on other iems. Not tiring listening them for very long time. Short sustain of the notes so theyre pretty analytical/detailed and you can tell apart every note so to say. Bass is not boomy but pretty tight and plenty, but not tiring as it can be on other iems with similar ammount of bass. Burn in to my ears doesnt seem to make any significant difference in sound. Easy one of my favourite ChiFi iems.
