It is great to be able to get up from the table and not cling to the cable, and now it is not required to remove the headphones from your head if you need to run away from the computer for a couple of seconds. Pros: - It's nice to be able to get up from the table and not cling to the wire. Different cons: The sound is still different from wired ones, and I won't claim that it's straight for the better. - The battery level is difficult to judge. - It's difficult to see how much power is left in the battery. To turn the headphones back on once they have been turned off, you must press and hold the power key.
