Shokz OpenRun Pro 2 review: bringing bass to bone conduction headphones

What makes these headphones unique is that the pods also contain open-air speakers that direct music towards your ears on the outside. They work in tandem with the bone conduction speakers, which vibrate your cheekbones to send sound directly to your inner ear. The open-air speakers handle the low tones, and the rest is fed to the listener via bone conduction.
