Zulu Exero is a bone conduction headset that lets you experience truly personal out-of-ear audio. Using a light vibration in the headset as they rest around your ears, music is generated just for you, without blocking out your surroundings. There are many situations where noise cancellation is unsafe and also uncomfortable. These headphones are the perfect alternative. Better than normal headphones because you can still hear the world around you. They're better than earbuds because they won’t fall out; they stay rested around your ears.
