ALTEAM Active Noise Canceling Headphones compare to Bose QC3

Reduce and even eliminate the noise from airplanes, train rides, or noise at home or abroad. 
ALTEAM acoustic noise canceling headphones employ Active Noise Canceling technology so you can actively reduce and even block ambient/outside noise. What makes these headphones better than any others?
Soft, high quality cushioning makes for a pleasant listening experience. The ear pieces rotate for a better fit. With such a good fit and soft, light-weight design, you hardly notice you’re wearing headphones! Active Noise Canceling requires power to run and batteries. Other headphones store the batteries in a box attached to the cable which weighs down the cable and pulls the headphones down making them uncomfortable to wear. The headphones by ALTEAM are designed with ease of use in mind. Batteries are stored in the headset itself. With the lightweight design, you don’t even notice the weight, and you won’t have to worry about a bulky battery compartment attached to your cable. The durable shell casing will protect your headphones while traveling much more than flimsy slip bags that sold with other headphones. Listen to the noise around you dissipate and even disappear as you relax with your favorite music.
