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 are pretty durable, good-sounding ear buds. The nature of ear buds' construction, with fine wires that are constantly being pulled on to dislodge from the ear or disconnect from the audio source, make it inevitable they will need to be replaced periodically. Having three teens using ear buds means that I am fairly discerning as a buyer, and these Sony EX Series are my go-to model. For the price-point (and even double it), they are the best-sounding, most durable ear buds we've found. I will buy more, but it's not the fault of the Sony ear buds!
