The included tips are very simple and very soft. They might not fit every ear. I didn't have any trouble, but you should consider using different tips of your choice.
Lows / Bass
The bass is awesome. It's quick and impactful, but not as deep as I would expect such impactful bass to be, some more sub-bass could make these earphones near perfect.
Mids / Vocals
The mids are very lively and loud, and make a great impression. They are not the most detailed mids around, nor the most accurate, but they will satisfy the avarage consumer.
Highs / Treble
The highs are pretty balanced, BYZ did a good job when it comes to avoiding sibilance. However, much microdetail was lost in the process. Still, most avarage consumers will find these highs quite impressive as they are.
