Need help to find replacement for dead blon bl03

Etype

Beginner
Hi,
I was using blon bl03 since last 4 yrs, with upgraded cable and eartips. I was happy with the sound quality. Today they got dropped on the floor and the left one cracked open, it has happened before but this time one of those thin wires inside snapped.
Should I just buy another pair of blon bl03?
While browsing i came across bl03 ii, is it better than bl03?
Are there better choices available till 3-4 thousand?
