Blend the sounds around you with your music – ­or tune them out
Using the AMBEO SMART HEADSET’s built-in mics, the Transparent Hearing feature lets you hear outside sounds to create the perfect balance between your surroundings and your music. This is ideal for bikers, walkers, joggers and anyone else who wants to be aware of what is going on around them without removing their headphones.

When it’s time to tune out your environment, the AMBEO SMART HEADSET’s Active Noise Cancellation blocks distracting sounds around you so you can enjoy your music and videos.
