Having your headphones on will quickly render it impossible for you to hear colleagues calling your name or the doorbell ringing, so the 'SoundBrake 2.0' awareness device is intended to ensure you never miss hearing something important again. The device works by taking a sample of the ambient sound in your environment and immediately letting you know if there is a deviation from it: say, someone calling your name or your phone ringing. The device will instantly enable you to hear it through the headphones to keep you aware of what's going on without having to feel completely oblivious.
The 'SoundBrake 2.0' awareness device is ideal for office environments, cyclists or anyone else who enjoys listening to music with their headphones.
