Casti Bose 45 Black

You feel it as soon as you put them on your ear.

Extra soft cushions seal the sound.

Then you press the switch and the noise disappears. The music starts and it's love at first listen.

That's the power of our latest generation QuietComfort headphones, now with a combination of noise-canceling performance and premium comfort, plus patented acoustic technology for deep, clear sound.

Characteristics:

- Wireless headphones with a perfect balance between silence, comfort and sound that you will enjoy all day.
- Everything starts with Acoustic Noise Canceling technology, the result of over 50 years of research.
- Tiny microphones hidden in the headphones for continuous measurement, comparison and reaction to external noise.
- That noise is then canceled with an opposite signal, resulting in fewer distractions - and more music.
- Use the button on the left headset to choose between Quiet Mode for complete noise cancellation or Aware Mode to let in some noise from your surroundings.
- Aware Mode brings the outside world into the headphones thanks to the microphones that capture the sounds around you and play them naturally through the headphones.
