When charging the Bluetooth turns off but they still work with the audio cable. Seems an odd design decision to turn Bluetooth off when you have external power but that's how they are. I used them on a flight across the pacific for 13 hours both on battery and while charging.
Sorry, there was a problem. Please try again later.Yes you can. I figured out the other day that you can plug the charger into your computer and use the aux cable to connect it to your PC's aux port. There is a bit of static when you're not playing anything but it goes away when you do. This is probably due to it charging at the same time.
Sorry, there was a problem. Please try again later.Yes and no. If the battery is dead you can still use them via the wired connection (of course with no noise cancellation) and you can connect the USB to charge. However, you can't charge while using Bluetooth.

Sorry, there was a problem. Please try again later.As many already wrote, you can use the headphone while charging, but not over BT. You have to connect the audio cable. But the sound quality and loudness may varie between sources. They deliver the best expirience only over BT and with a high-end analog audio device. I wonder why they designed it that way. It would be very odd if I could not use my laptop or phone while they charge.
