On my first time using this, I was amazed (and still am) by the details, clarity and openness that this headphone gives. Bass is lower than expected, but it is enough for plenty of songs. The mids, vocals are really just exactly on point, and the treble again, just crisp and detailed/neutral (might be too much for some).
Where this headphone really shines is the potential for improvements.
Don't like the clip-on design? Just buy a headband for it. This makes the headphone MORE comfortable than usual. Pads too thin for your liking? Custom pads are easily available and is easy to swap. Wanna change cables easily? MMCX connector mod is the way to go. (Requires bit more effort though.) There's just plenty of ways to improve this headphone that makes it more worth for longevity.
Overall, definitely worth the money:
1. If you're looking for detailed/crisp/neutral music experience.
2. Want to experience headphone modding without breaking the bank.
