1.Any delay on sound when watching TV or Videos?
No delay. I watched a few movies while flying both from my iPad and through the plane entertainment system and no delay. I was using these in both wired and wireless modes. Great headphones all around.
2.Are these good for people with large head and ears? They will fit most heads and the ear cups most ears. If you're int he upper 25% of people with a big head and ears, these may be snug, but they'll fit most people quite nicely.
3.Can I use it for phone call? Yes, it connects via Bluetooth.
4.Can i just use these as noise cancelling headphones? no music or anything, just ANC turned on? Yes. Just power them on and turn on noise cancelling and they'll work just fine.
5.does it have microSD slot? No, it does not have.
6.Do these headphones support quick charge? No evidence of that one way or another in the instructions. It charges by a usb connection.
