The audio quality is really good comparable to *** high end headphones. These headphones sound great and are very comfortable to wear with 30+ hour play time. If you want to save battery. just plug them into any music device with a cable. As far as noise canceling goes, it can block repetitive noise effectively. The sound quality gets a little bit lower but can block background noise that has a repeating pattern like engine noise or washing machine noise. So I would recommend to use this function when you are in an airplane or car or any situation where there is noise with repeating pattern. Overall, this is one of the best noise canceling headphones under *** and would recommend to anybody who is looking for high quality headphones but do not want to pay $$$$$
These headphones have excellent quality sound. Also, the wireless headphones prevents entanglement with my jacket (which i hated with my plug-in earphones). I love these headphones and will buy more in other colors to change up.
