With the Fresh 'n Rebel Clam ANC Wireless disturbing environmental noise is a thing of the past. These Bluetooth headphones have active noise canceling. This technology eliminates ambient noise so you can listen to your favorite music in peace. Because of this, you do not suffer from fellow passengers or you work concentrated in the office. You stream music in cd quality thanks to the aptX Bluetooth profile. This means that no signal loss occurs when you stream music from your smartphone to the headphones. Due to the battery life of 30 hours (without noise canceling 35 hours) you can listen to music without the copy. Is the battery empty? You can listen further thanks to the included 3.5 mm audio cable. That way you will never be without music.
