Both of your ear canals are different shapes, sizes and angles so you will never have perfect balance even if your drivers are perfectly matched.

Only peeps I've seen shilling these are Crinicle and tech tubers.

I was equally disappointed with the sennhieser mtw's, they are on par with £50 wired chifi's. Open them up and you can see why.
