I have been on a search for the perfect wireless headphones for a year now. I have many wireless and wired headphones including Denon, Bose, Beats, Jaybirds, OPPO, and more. Up until these came out my Denon's were my go to wireless over-ear phones. To make this short and sweet, ill compare them all. If you want the best wireless headphones and noise cancellation is not important to you, get the Denon. They are extremely comfortable, fold flat and sound incredible. If you want portability, get the Jaybirds. When I travel I use my Bose because up until now nothing beat its active noise cancellation. However, these sony cans are pretty comfortable (though not quite as comfortable as the Denon), the sound is very good but again not as great as the Denon, but the noise cancellation is on par with the Bose (maybe even a bit better!) and the build quality on this is very nice. I am very happy with these. I am hoping that after using them for a while that the sound improves slightly. Again, they sound fantastic, but I have been told that headphone ned to be broken in. Im not sure if thats true. I highly recommend these as the overall best choice if your priority is noise cancellation, sound quality and you need them to be wireless After a few days of using these I love them even more. Since I received them I used them on a flight and the noise cancellation was on par with Bose and those are wired. I haven't had any issues with comfort after wearing them for a few hours at a time and the battery seems to last forever. Sounds is a bit better than I originally thought. It seems a bit more flat compared to my Denon's . Overall these are fantastic in every way. If I could I would give these a 4.5 out of 5.
