text: The comfort and quality for these headphones are amazing. I've tried a couple of over the ear headphones and this one is the most comfortable for medium sized ears. I'm no audiophile but the quality is as good as many of the reviews make it out to be and compared to the microsoft surface headphones, they are noticeably better. The one main issue I have with these headphones is its bluetooth feature. Usually, once my bluetooth speakers or earbuds connect to my pc, I can play from any source at the same time or switch between the sources without the secondary source being muted. These headphones however do that. If i were to play a game such as League of Legends and watch a youtube video while in loading screen and swap back, all my audio for the game is muted. The only way I can get the audio back is by restarting the game. Another example is if I'm editing music on Fl Studio 20 and then play a youtube video, the youtube video is now permanently muted until I close out of Fl Studio. I never had this issue if I'm connected to my pc via the wire provided in the package, but I primarily purchased these over the older m50x because of the bluetooth feature. It's very frustrating to constantly be cautious about what I play because I can potentially mute an application entirely. I attempted to update the firmware but my firmware update always fails to go through. I follow all the steps that the Audio Technica app gives me to the T and I still cannot seem to successfully update the firmware. This is really disappointing that the bluetooth on this headphone sucks because of how amazing the sound quality and comfort is. The sheer amount of inconveniences I go through and the amount of changes I had to make on my everyday workflow in order to work around this bluetooth issue is very annoying. The only reason I have yet to return them is because of how amazing they are, besides the bluetooth. Please fix it or if it has been fixed with the firmware update, fix the app because the app is the only way to update its firmware. I've checked on many online forums on how to update the firmware and the app seems to be the only solution. If this one issue is fixed, I'd say this is the best bang for your buck wireless studio headphones on the market
