Hello! This is my first review. DAP: Xiaomi Mi4 C Player: AIMP Source: 16 bit FLAC     Sound Impressions：   Low: The bass is tight, good for those who dont like bass. Mid: The main reason why i love this IEM. You can hear the vocal clearly and the vocal is not mixed with other instrument. High: The treble is not too sharp.     Conclusions: Absolutely worth for $50. Nice isolation, good resolution and the mid is good too. The soundstage is so ******* great, there's no IEM in it's price that can match HI1200...
