Build Quality on mid-low range IEMs?

[dfink]

Hey guys,

I've been lurking for a while but finally need some advice I can't find elsewhere.

Last set of IEMs I picked up were the soundmagics and I was really happy with them.. except they just broke. They held up pretty well but since I'm a dancer, and I'm constantly moving around with my phones and they tend to go pretty quick (wrecked my old shure e2cs in about 3 months....).

I want to try something else this time around so I was wondering if I can get some advice as to which of these are going to hold up the best (or if you have other suggestions). Put this list together mostly from browsing here and head-fi.

Maximo i590
Hippo Pearl
Meelectronic Ai-M6
Visang r02
Brainwavz m1

From what I understand they're all pretty good value so I just need to know what's going to last me the longest. If I have to say I'm leaning one way it's probably to the brainwavz just because they're on sale if I pre-order em in the next couple days... but looking forward to your advice. Thanks in advance~
