Review: First Impressions - The product is really good , not just the build quality but the sound quality is also so good and very clear when compared to any earphones or earbuds at this price point . I would suggest everyone to once try IEM and experience your loved music again for the first time . At this price point the best IEM is the one I bought i.e., KZ Castor . You can experience the music from very low frequency to very high frequency. The interesting thing from the product is even though the sound can reach really high frequency the clarity is top notch and its not missing . I would really suggest everyone to once try IEMs in their life .
Review: Felt like listening to music for the first time. - Gives a whole new feeling while listening. Wire: The wire quality is good. Fit: As there are three eartips, the fit won't be a problem. But one might struggle with the design and mechanism of hooking and the form factor Sound: Even the bass boosted version, out of the box felt balanced and not bass heavy, But the EQ pins come handy.
