We have all tried headphones with powerful noise cancellation. Not being aware of your surroundings is not always safe or ideal. SoundBrake can change that. It is a smart device that listens to your surroundings and streams outside sound when they are above an alert level.
The device can be attached to any headphones or audio player to keep you aware of what happens around you. Simply connect the device, press the appropriate button to create an alert level, adjust it, and the rest is easy. The battery lasts over 50 hours.
