    1.5/5,
    Pros - Have bass
    Cons - No resolution; no highs; nothing at all; questionable ergonomics
    A not garbage cheap IEM turns out to be total garbage. In spite of the fact, it is very popular and revered among non-enthusiasts. No treble whatsoever - after 10KHz you meet dead end cliff. Muddy bass that intrudes into mids. They are so awful that even some 3 times cheaper IEMs sound much better. Did I buy a fake? Probably not for similar reviews come from people who bought them from proven retailers.
