These are Passive Noise Isolating Wireless Bluetooth 4.0 Stereo Headphones with a Foldable Design and a Portable Bag provided. This foldable Headset is not only designed for saving your desk space but for carrying them in the provided bag. Impressive Sound Quality is The Ultimate Goal of these Headphones. 

Never Power Off, Both Wireless and Wired modes. The wireless mode gives battery times to 20-hr music time/ talking time in a single charge, instead of 13-15 hrs. The Wired mode makes it so you can also use it as a wired headphone with the provided cable so the headphones will never power off.

These headphones are passive noise isolating, NOT active noise cancellation (ANC). They cannot cancel all noise completely but it also won't drain the battery and damage the sound. As an additional factor of sound quality, it is better than ANC. 

The closed-back design provides immersive Hi-Fi sound with CSR chip and 40mm driver together. If you care more about Noise Cancellation than Sound Quality, you may consider other alternatives.

Depending on your head, ear size, and shape, these headphones may feel a little tight (feels like“on ear”) for someone to wear which is designed to avoid sound leakage. In case of that and to get both audio and wearing comfort, please take off the headphone every 1-2 hrs to get your ears to relax.
