The revolutionary technology of the Aftershoks Treks Titanium Headphones allows the wearer to remain fully aware of their surroundings, resulting in them being the only headphones currently approved for national races by the England Athletics Association. The open ear design of the headphones utilises bone conduction technology, which allows soundwaves to travel directly through the cheekbone to the inner ear rather than through the air to the ear drum as ordinary sound does. This means that the ears remain completely uncovered, allowing the wearer to hear everything around them while still listening to music, podcasts or phonecalls. Ideal for road and group runners who need to stay aware of their surroundings to ensure their safety.
