Not long after the release of the Pistons 3.0, everyone on the Pistons threads – myself included – was surprised to hear news about a new IEM from Xiaomi. Immediately the “first responders” set up shop and gathered scraps of info quickly, and this new IEM was dubbed the Pistons 4.0 – at least, until the translations came out. No, this is a brand-spanking new IEM from the smartphone manufacturer featuring a hybrid dual driver design at the same price the entire Pistons line was sold at -- $16, or CNY 99. That, in and of itself, is a crazy – and risky – feat to pull off.

The question is – did Xiaomi pull it off right? Find out after the jump.
