with following features (everything compared to Tin Audio T2 because that's all I have for now)
- Better isolation. T2 really lack there
- Less prone to tangling. I have used many IEM over the years and T2 are the worst with it. They tangle too easily
- Lower length of the earpieces. It's really hard to use T2 while lying down in the bed as the earpieces are just too long
- After considering all the above if I still have options to choose from, then the final factory would be sound quality. Signature can be whatever
