Cost-effective！

Unbelievable for a budget IEM, the detail resolution is very good, from subclass to mids and treble, there's great definition and clarity, the bass is controlled, tight and punchy, and mids are clear and detailed, with good natural texture, the treble is extended and sparkly, the entire frequency range feels well represented. Highly recommended trying these IEM's. One of the best budget IEM's I have heard this year, and punches well above it's price range in detail.
